ACKNOWLEDGEMENTS
This draft classification is truly the product of the whole Natural Heritage & Endangered Species Program and the cadre of dedicated field ecologists and naturalists in Massachusetts. Many years of many people's field work and observations, with data compiled in species reports and natural community descriptions, contribute to the core information in the draft classification. Bruce Sorrie's extensive field notes, detailed reports fi^om Glenn Motzkin and Tom Rawinski, and Pam Weatherbee's Flora of Berkshire County as well as her field forms were particularly helpfiil in establishing the details of community composition in Massachusetts. Reports submitted to NHESP's Small Research Contracts Program and Ecological Restoration Program also contributed significant information to the classification. Descriptions of communities fi^om classifications fi"om surrounding states and from The Nature Conservancy have also contributed greatly to the information in the draft classification. Brian Reid, Karen Searcy and Sally Shaw responded to our pleas to contribute written descriptions on communities with which they were particularly familiar. We added the animal and synonym information to these, and did some editing for consistency.
Personal communications and community and rare species field forms fi'om the following people provided additional habitat information and site descriptions: Henry Barbour, Michael Batcher, Jesse Bellemere, Robert Bertin, Beverly Brown, David Burg, Fricka Caldwell, Caren Caljouw, Nancy Childs, Frances Clark, Tom Cramer, Peter Dunwiddie, Ted EUiman, Tamara Enz, J. Garcia, Jennifer Garrett, Meryl Goldin, Matthew Hickler, D.W. Holt, David Hunt, Jerry Jenkins, B. Johnson, Jennifer Kearsley, Heather Lanza, Richard LeBlond, Bruce Lindwall, Robert B. Livingston, Roberta Lombardi, J. P. Lortie, David Lovejoy, Frank Lowenstein, Julie Lundgren, Mark Mello, Glenn Motzkin, Carol L. Nilson, PhiUp Nothnagle, Allison Park, Charlie Quinlan, Lloyd Raleigh, Tom Rawinski, Brian Reid, Christine Reid, Julie Richburg, Steven Roble, Karen Searcy, Sally Shaw, Scott Shumway, Tim Simmons, Darren Singer, Lesley Sneddon, Paul Somers, Bruce Sorrie, Daniel Sperduto, Valerie Stone, Patricia Swain, Elizabeth Thompson, Tom Tyning, Pamela B. Weatherbee, Henry Woolsey, Bob Zaremba, and Tad Zebryk.
Pat Huckery, Matt Bume, Tim Simmons, and Brad Blodget contributed rare animal information, and Matt Bume and Pat Huckery identified communities that can fimction as vernal pool habitat. Brad Blodget, Tom French, and Tim Simmons supplied information on more common animal species, especially those using terrestrial communities - but the interpretations and restatements of their information should not be held against them.
The data organization and availability reflect the effective management by several data managers and hoards of interns, work study students, and volunteers over more than 20 years. Preliminary conceptual design and organization was accomplished through meetings of the authors, JuUe Lundgren, Henry Woolsey, and Vicki Frey. Vicki Frey and Jean Collins developed the Access database. Jean wrote and enabled the clever *macro' that italicized the scientific names. David Szczebak and Laura Chaskelson produced the sub- ecoregion distribution maps.
Several people commented on early versions of different sections of this draft classification, but like the zoologists, they shouldn't be held accountable for the use we made, or didn't make, of their input. We are very gratefiil for the comments fi-om Jesse Bellemare, Russ Hopping, Anne-Marie Kittredge, Glenn Motzkin, Tom Rawinski, Tim Simmons, and Pam Weatherbee. Some of the biggest issues, including names and levels of splitting, remain unresolved, and we hope will be addressed again in comments on this draft. Henry Woolsey, Marea Gabriel, and Darren Singer provided encouragement and editorial comments.

Introduction
The main purpose of this classification is to provide a useful fi-amework for describing, inventorying, and tracking natural communities in Massachusetts. This natural community classification is biased to describe vegetation at a scale that is meaningfijl for conservation and land protection. A classification provides a convenient mechanism for reducing the complexity of natural vegetation to a relatively small number — 105 in this case — of somewhat homogeneous and relatively easily understood, but abstract and artificial, groups. Any classification requires somewhat arbitrary categories and lines between types and classifications differ on where the lines are drawn. Part of the reason for disseminating a draft is to encourage input into the categories and their delineations. Vegetation classifications are influenced by their intended use - the use of this one is for conservation, and indeed focuses on the uncommon.
To protect the components of biodiversity, their patterns of distribution and their current patterns of conservation need to be evaluated and tracked. One aspect of this is to evaluate the conditions and distribution of natural communities across the state. Tracking natural communities requires having knowledge of what they are. A beginning of knowing natural communities is to name and describe what is known and give a common parlance for discussing the communities. Such a fi^amework also allows identification of what isn't as well known, and encourages focus on gathering that information.
Our intent is to describe communities that can be identified in the field and to accurately (if arbitrarily) divide the vegetation of Massachusetts into identifiable and useful categories. Terrestrial, Palustrine, and Estuarine communities are included; Aquatic communities have NOT been addressed in this classification. In this classification of natural communities, attempts have been made to use community names that are recognizable and meaningful to a broad conservation audience including writers of town open space plans, land managers, environmental reviewers and consultants, and ecologists doing field studies.
In defining the composition and structure of the community types, we have begun identifying variations within those community-types; further information on the variations may lead to further splitting or lumping of the identified types in later versions of the classification. In particular, there is a complex of communities dominated by oak trees and another group (inter-related) dominated by red maple. Increased data may lead to sphtting these groups differently than they are now divided. Comments on this public draft should lead to refinements and improved descriptions of the community types. Suggestions on other community t>pes that could be split or consolidated would be considered. Descriptions of t>pes of cultural communities (plant communities planted and maintained by humans for direct use by humans or domesticated animals such as forest plantations, orchards, and pastures) could be expanded, but most are not of conservation focus, so will probably continue to be lumped into a few groups.
Many communities occur with others in mosaics that share conditions and processes, such as water flowing through a wetland complex with no one community-type independent of the others or the unifying conditions. Communities are most effective as units of conservation when the controlling ecological processes can be maintained or restored. Putting communities into the fiinctional systems of which they are a part will be another step in the classification. For now, some of those ideas are addressed in the part of each community description under the header Environmental Conditions. Such functional systems are not actually the same as the hierarchy of a key - that is a rock cliff face may be found in a key under non-forested, open communities, but is found on the ground surrounded by forest.
The communities described here are in exemplary condition, the type communities: not all real communities meet the criteria of the abstract, but still qualify as that community t>pe. Many actual communities are disturbed by nature or humans, some are in climatic, topographic, or geological conditions different from the idealized, and others occupy some middle ground between described communities. Because communities are made up of plant species that have individual responses to environmental variables, the communities described grade into other community-t>pes. In addition, the role of land use histor>' is very important in the location and definitions of natural communities in Massachusetts. Three hundred years of intense use of the land in the state appears to have had a homogenizing effect that overrides some of the
influences of climate and landscape position (for example, see Foster et al. 1998, and other papers from the Harvard Forest). Some of this homogenization of communities is reflected in the difficulty of defining distinct community types and in the prevalence of mid-successional species in many of the community descriptions, and in the actual community occurrences.
The community-types that are described here are parts of the habitat for the animal species that use them. Birds may nest in one type of community, feed in another, and then leave entirely. Other animals also move between community types for different needs. Generalist species might have individuals occurring in a variety of different communities types.
Despite the problems of classification, we do find recurrent groupings of plant species, and associated animals, that do share responses to environmental conditions. Species that have restricted ranges and particular environmental requirements are often used as indicators of the communities in which they occur. Other species are found in a range of conditions and are occur in a variety of community-types, so are less useful as indicators, although they may be characteristically present in a given community type. These natural groupings of species, or natural communities, tend to vary simultaneously in response to soil moisture gradients, temperature gradients, and nutrient gradients, in a multidimensional, rather than linear, way. Thus, there are southern and northern versions of dry to wet gradients, acidic to less acidic, and nutrient poor to nutrient rich communities, and all the other interactions as well. While not all the possible variations result in distinctly different communities, there is a lot of variation in the real world.
Relationship to other classifications
This classification focuses on the natural communities of Massachusetts, but they are closely related to the natural communities of the region and particularly the surrounding states. The Massachusetts community descriptions include lists of synonyms for the surrounding states, all of which have developed individual classifications for their natural communities. The Nature Conservancy (TNC) with the Association for Biodiversity Information (ABI), has been developing a classification for the region within the United States National Vegetation Classification (USNVC) system. We've included the USNVC/TNC synonyms for those who want more finely divided community-types - the TNC Associations. The accuracy of the cross-walk to the synonyms is variable in this draft. Synonymy with other state's classifications are, of course, confounded by geographic differences in species distributions in the states, as well as issues of different levels of definitions. Clarification of these is one goal for the more final version of the classification. We also include synonymy with the previously used names in Massachusetts, some of which are more broadly defined than in the current classification. Many of the cross-walks to the old Massachusetts classification (Rawinski 1984), especially for the northern forest types, lack precision. That is at least partially a result of the lack of clear boundaries between types.
Organization of the classification
This draft classification divides natural community types into three major sections: Terrestrial, Palustrine and Estuarine. The Tables of Contents of each section double as keys, but are not dichotomous. Within the sections, the structural dominance - growth form or physiognomy such as forest, shrubland, herbaceous, and open or sparsely vegetated - is used as a division of types. The forested categories in the terrestrial and palustrine sections are subdivided into evergreen, deciduous and mixed.
We used a significant presence of water as the definer of what was palustrine, and the presence of water with some salinity or tide for inclusion in the estuarine category. All tidally influenced communities are in the estuarine category whether the tidal water is saline or fresh. Salt spray communities not influenced by tides are treated as terrestrial.
Terrestrial: The vegetation of terrestrial communities is not significantly influenced by standing or moving water. The forested community types have more than about 25% tree canopy (50% in the palustrine section), which includes woodlands of USNVC/TNC and other classifications. If mature trees are absent, and if shrubs are present forming more than about a 25% shrub layer cover overall, the community is considered to be a shrubland. Herbaceous communities are relatively open communities with neither forest nor shrub
Introduction- ii Classification ofthe Natural Communities of Massachusetts DRAFT July 2000
canopies and have more than about a 25% vegetated cover. Open or sparsely vegetated communities are divided by their substrate type, rock or sand for convenience.
Palustrine: The palustrine section of the Massachusetts natural community classification includes all freshwater, non-tidal wetlands dominated by trees, shrubs, or persistent emergents, including mosses and hchens. This definition is slightly different from Cowardin (1979) who also included small, shallow aquatic beds with submersed and floating-leaved aquatics, and tidal wetlands where salinity due to ocean-derived salts was less than 0.5%. In this draft Massachusetts' classification, submersed and floating leaved aquatics will be included in an as yet unwritten aquatic section, and all tidal wetlands are included in the estuarine section. The palustrine section does include riverside communities that receive annual or semi-annual overbank flooding, e.g. floodplain forests. High-terrace floodplain forests (although technically terrestrial communities) are included in the palustrine section in order to group them with other floodplain forest communities.
Estuarine: Estuarine communities are subject to varying salinity, tidal actions, and wind. Estuaries include tidal habitats and adjacent tidal wetlands in which ocean water is at least occasionally diluted by freshwater from the land. Estuarine areas extend landward and up streams to where oceanic salts (formally defined as above 0.5 ppt salinity in an annual average low flow period) or tides (including fi'eshwater tidal areas) have an influence on the vegetation. Hyper salinity (compared to the ocean) may occur temporarily in some areas from evaporation (such as in salt ponds). The estuarine area extends off-shore to areas with freshwater influence on the seawater, called subtidal communities in this classification.

Request for information
This classification identifies as examples sites where the community-types can be found as occurrences, on lands with public access in Massachusetts. Our database does include sites on less accessible land. We are in the process of building our database to include good occurrences of all community -t>'pes, with the most common being tracked only by exemplary occurrences (definitions of exemplary are being developed for each community type), and the rarest being tracked by all known occurrences, with a sliding scale of rarit>' and quality between. We would like to ultimately know what types are on protected - conservation - land, and what types need further protection. Then, with the management and restoration knowledge also being developed and collected, we will be in a better position to continue to protect the biodiversity of Massachusetts. We are asking for examples of additional locations, or better locations of community t>pes; this will not necessarily result in those locations becoming published information. See Appendix A for a list of estimated inventory needs by community type.
Management needs of communities are seldom well known. In the descriptions we have included some of the management issues identified by field biologists who have been to occurrences of the communities
Natural Heritage & Endangered Species Program July 2000 Introduction- iii
described. We hope to encourage further discussions of the management needs of the described communities by raising the management issues for each type.
Refinement of described community types
This draft of the classification of the natural communities of Massachusetts was written in order to provide a basis for discussing and conserving diversity of the types of vegetation in the state. The primary aim is to describe natural communities of conservation interest in Massachusetts, while including all the vegetation of the state. The overall tendency in this classification is to lump rather than to split. However, communities that have been well-studied (e.g. floodplain forests, acidic peatlands, Atlantic white cedar swamps) are usually more finely divided. Mostly, though, the many vegetation associations occurring within broadly defined communities are not described separately. Instead, the variation in vegetation is included within the vegetation description field and referred to as Associations when known and considered subtypes. As more data are accumulated, more divisions and reorganization will undoubtedly occur.
This classification represents the best of our knowledge about Massachusetts' communities fi-om the field data and literature that we have compiled to date. It is by no means complete or absolute. Instead, it should be regarded as a fiamework that can be field-tested and revised. Communities can be added, deleted, divided, or combined as we expand our knowledge of Massachusetts' natural communities. There are inconsistencies, some fields are incomplete, some community descriptions overlap. Any assistance with refining those issues would be helpful.
The plan is to collect data, have discussions with ecologists state-wide, and consider comments on this draft ~ and to produce a more definitive classification. All comments, feedback, and community information are welcome and appreciated. Your help will greatly improve the result.
Introduction - iv Classification of the Natural Communities of Massachusetts DRAFT July 2000
PAGE GUIDE
Community Name: Name used to describe the community in Massachusetts
Community ELCODE: Unique ten digit alphanumeric element code (ELCODE) assigned to the community.
SRANK: Community state rank (SRANK) that reflects the community's rarity and threat
within Massachusetts, with regard to its regional rarity and threat. The SRank s>'stem was developed for Natural Heritage programs by The Nature Conservanc>'. The SRANKs are as follows:
Sl= Typically 5 or fewer occurrences, very few remaining acres or miles of stream, or especially vulnerable to extirpation in Massachusetts for other reasons.
S2= Typically 6-20 occurrences, few remaining acres or miles of stream, or very vulnerable to extirpation in Massachusetts for other reasons.
S3= Typically 2 1 - 1 00 occurrences, limited acreage or miles of stream in Massachusetts.
S4= Apparently secure in Massachusetts.
S5= Demonstrably secure in Massachusetts.
SU= Status unknown in Massachusetts.
Tracked: Yes/No field. Yes means that the community is tracked in MNHESP's database.
MNHESP tracks examples of communities that are ranked SI -S3. Communities that are ranked S4 or S5 generally are not tracked, except for exemplary occurrences. Some newly defined S3 communities (draft) are not yet tracked.
Map of the ecoregions and sub-ecoregions of Massachusetts:
Ecoregions (or ecological regions) are areas of relatively homogeneous ecological systems, including vegetation, soils, climate, geology, and patterns of human uses. Ecoregion boundaries have been developed for the United States to provide an ecological framework for inventorying and assessing environmental resources. Massachusetts falls within two ecoregions of the United States — the Northeastern Highlands and the Northeastern Coastal Zone. Sub-ecoregions of Massachusetts have been delineated (Figure 1; Griffith et al. 1994), and they are particularly useful for statewide ecological inventory and assessment activities, including vegetation classification.
There are thirteen sub-ecoregions in Massachusetts. Complete descriptions are given in Griffith et al. (1994), but a brief synopsis of their descriptions is given below:
Northeastern Highlands:
The Taconic Mountains sub-ecoregion is a hilly and mountainous region of western Massachusetts that includes ML Greylock, the highest elevation in the state (3491 feet). Streams are generally small and high-gradient, and there are few lakes. The vegetation is primarily northern hardwoods (maple-beech-birch) with spruce-fir at higher elevations. The Western New England Marble Valleys, also known as the Berkshire Valley, consists of calcitic and dolomitic marbles and limestones bedrock. Surface water alkalinity values in the area are the highest in Massachusetts (>1000 fieq/L; Griffith et al. 1994) due to the underlying limestone and marble. Alkaline groundwater results in mineral-rich and species-rich wetlands in the region, particularly calcareous fens. The Hoosic and Housatonic Rivers are the major drainages. The Green Mountains/Berkshire Highlands includes the southern extent of the Green Mountains and the Berkshire Hills; elevations range from 1000 to 2500 feet. Northern hardwoods and spruce-fir characterize the forested uplands. The Deerfield and upper Wesffield Rivers are the main river basins. The Lower Berkshire Hills is similar to the Green Mountains/Berkshire Highlands sub-ecoregion except that it has an overall lower elevation, generally 1000 to 1700 feet. Spruce-fir is generally lacking, and northern hardwoods are mixed with transition hardwoods (maple-beech- birch, oak -hickory). Lakes and ponds are abundant compared to the rest of western Massachusetts. The Berkshire Transition ranges in elevation from 400-1400 feet, and forest t>pes are transition hardwoods and northern hardwoods. Surface waters drain to the Westfield and Connecticut River basins. The Vermont Piedmont has a similar elevation range as the Berkshire Transition, but underlying limestone and marble result in surface waters with higher alkaliruty (500-1000 |ieq/L). Surface waters drain into the Deerfield and Connecticut River basins. The Worcester/Monadnock Plateau contains the most hilly and mountainous area of Massachusetts' central upland. Elevations range from 500 to 1400 feet with some peaks above 1800 feet (Mt. Watatic and Ml Wachusett). Transition hardwoods are common, but
Natural Heritage & Endangered Species Program July 2000 InU-oduction - v
northern hardwoods also occur. Forested wetlands are conunon, and forested and non-forested peatlands are abundant Surface waters are acidic with alkalinity values less than 50 |ieq/L.
Northeastern Coastal Zone;
The Connecticut Valley is characterized by thick outwash, alluvial, and lake bottom deposits overlaying sedimentary bedrock. Surface water alkalinity values are generally above 500 j^eq/L. Central hardwoods (oak-hickory) and transition hardwoods are the major forest types. The Lower Worcester Plateau/Eastern Connecticut Upland ranges in elevation from 500 to 1200 feet. The soils of the area developed primarily on glacial till in the uplands, and on stratified sand, gravel, and silt deposits in the valleys. Surface waters are acidic and drain primarily into the Chicopee and Quinebaug River systems. The Southern New England Coastal Plains and Hills is the largest sub-ecoregion in southern New England and is variable in its topography and bedrock. Bedrock types are mostly granites, schist and gneiss. Surface water alkalinity values are generally lower than in the Connecticut Valley, ranging from less than 50 to 500 |.ieq/L. Central hardwoods are dominant The Boston Basin has low, rolling topography that is dominated by urban and suburban land. The Narragansett Bristol Lowlands are similar to the Coastal Plains and Hills, but bedrock outcrops are uncommon, and thick glacial till and outwash deposits cover the area. The lowlands are flat to gently rolling with elevations less than 200 feet. Surface water alkalinity values are generally between 100 to 300 )ieq/L, but several areas have values less than 50 fieq/L. The vegetation is mostly central hardwoods. The CapeCod/Long Island sub-ecoregion is characterized by terminal moraines and outwash plains left by the glaciers, and by coastal deposits. The landscape is influenced by wind and water. Elevations are less than 200 feet. There is a moderate maritime cUmate, and stunted oak and pine forests are typical. Surface water alkalinity values are low (less than 50 ^eq/L).

Classification of the Natural Conununities of Massachusetts
DRAFT July 2000
In the vegetation classification, each community description is accompanied by a sub-ecoregion Une map showing the sub-ecoregion boundaries. Sub-ecoregions in which the community type is known to occur (i.e. MNHESP has field data for the community including vegetation descriptions and/or plot data) are shaded in dark gray, and the sub-ecoregions with probable occurrences (i.e. field data are currently lacking but the community has been observed in the sub- ecoregion or the sub-ecoregion is known to have the appropriate physical conditions) are shaded in hght gray. If the community is not believed to occur in a certain sub-ecoregion, then that sub-ecoregion is left white.
The community sub-ecoregion maps are intended to give the user an idea of where s/he may encounter a certain community type and also to identify sub-ecoregions for which community data are needed. Readers are encouraged to look in sub-ecoregions identified as having probable occurrences of the community (light gray). All new data and distribution information is welcome and much appreciated.

Names used for the Massachusetts community in other natural community classifications. If a synonym is listed without any modifier, then the Massachusetts community is basically equivalent to the synonym. Sometimes the following modifiers are used: "includes" means that the Massachusetts community includes the communities listed, "included within" means that the Massachusetts community is included within the community listed, "similar to" means that the Massachusetts community is similar but not equivalent to the communities listed, and "not described" is used when the Massachusetts community has no synonym in that classification. Question marks indicate uncertainty about synonyms.

ACIDIC ROCKY SUMMIT / ROCK OUTCROP
CT2A1A0000
S4
No
Concept: A widespread, open, community of low shrubs, scattered grasses, mosses, lichens and occasional trees
found on rocky summits with exposed acidic bedrock or on rock outcrops where bedrock is acidic.
Environmental Setting: This community is found on rocky summits (balds) or ridge tops with exposed acidic bedrock or on rock
outcrops derived from acidic bedrock. These areas are characteristically dry, with httle or no soil and can often be found as open patches within the ridge-top pitch pine or dry, mixed oak communities. Although it can be found on flat surfaces, it is more typically found on steep slopes with aspects varying from SE through SW. Vegetation is concentrated around the edges or is found in pockets of soil within the outcrop. Ridgetop Pitch Pine / Scrub Oak Communities, or other ridgetop communities are often around the open patches of the Acidic Rocky Summit / Rock Outcrop Community. Examples of the Acidic Rock Cliff Community may occur below rocky summits, sometimes with intervening ridgetop or other forest/ woodlands.
Vegetation Description: Low shrubs and scattered clumps of grass dominate this community. Vegetation is discontinuous. The
exposed rocks often have extensive patches of lichen and moss. Canopy cover is largely absent but trees commonly found near the margin of the bedrock areas include pitch pine {Pinus rigida\ white pine (Pinus stTX)bus), and red oak (Quercus rubra), and may also include Red Pine (Pinus resinosa) native in this habitat The dominant shrubs include scrub oak {Quercus ilicifolia), huckleberry (Gaylussacia baccata), early sweet bluebeny (Vaccinium pallidum\ low sweet bluebeny (V. angustifolium\ black chokecherry (Aronia melanocarpa\ and dwarf serviceberry {Amelanchier stolonifera). Dwarf chestnut oak {Q. prinoides) can also be found, but not as commonly. Herbaceous ^)ecies include little bluestem {Schizachyrium scoparium), poverty grass (Danthonia spicata\ common hair grass (Deschampsia flexuosd), Pennsylvania sedge (Carex pensylvanica\ pale corydalis (Corydalis sempervirens), and cow wheat {Kielampyrum lineare).
Associations:
Habitat Values for Associated Fauna:
Most animals of rock outcrop communities are not sensitive to the chemistry of the rock, but rather are responding to the elevation and dryness of the habitat Any differences in resident fauna between calcareous and acidic outcrops are most likely due to geographical differences in species distribution rather than to qualitative differences among the types of outcrops. Outcrops tend to be fairly small, and only a part of the habitat of most vertebrate animals. Small mammals of rock outcrop communities include those of dry habitats such as white footed mouse (Peromyscus leucopus), red-backed vole (Clethrionomys gapperi), short-tailed shrew {Blarina brevicauda) and, in grassy / sedgy areas with some soil accumulation, meadow voles {Microtus pennsylvanicus).

The major threat is probably the use of the areas as viewpwints. This can destroy the vegetation by trampling. The larger and steeper areas where the community occurs are probably stable and not likely to be overgrown by trees. Smaller areas may be overgrown during succession.
Build trails to avoid these areas and/or educate the pubhc so they imderstand how to protect the fragile areas. Controlled bums may be useful in keeping areas open.

CmCUMNEUTRAL ROCKY SUMMIT/ ROCK OUTCROP COMMUNITY
CT2A1B0000 S2S3
i^'^
Yes
An open community of grasses, sedges and herbaceous plants ocoining on rocky siimmits, ridges or outcrops where the exposed bedrock is circumneutral.
This community is found on traprock ridges where it occurs on open ridge tops or steep slopes u-here the traprock is exposed. It is found on slopes facing SE through SW. These relatively small open areas are often found within an oak forest matrix near hickory-hop hornbeam communities with vAdch it shares a number of herbaceous species. The commimity is also found on other types of circumneutral substrates such as conglomerate. The Circumneutral Rocky Summit / Rock Outcrop Community grades into the Circumneutral Rock Cliif Community near clifTs. Both types of sites are dry with soil confmed to cracks in the rock.
Grasses, sedges and forbs dominate this commimity. Occasional isolated trees of eastern red cedar (Junipents virginiana), shagbark hickory, (Carya ovata\ sweet pignut hickory (Carya glabra/C. ovalis\ and white ash (Fraxinus americana) can also be foimd, so that some examples have an open, savaxuia like appearance. The exposed rock is often covered with lichen, and mosses (Polytrichum spp.). Except for the Carolina rose {Rosa Carolina) and bearberry (Arctostaphylos uva-ursi\ wWch are found on a nxunber of sites, shrubs, including the less common hackberry (Celtis occidentalis var. pumila), are usually restricted to the edge of the openings. The herb layer can be patchy, occupying area between outcrops of rocks or can be almost continuous where rocks are brokea Dominant species include Pennsylvania sedge, (Carex pensylvanica), parasol-sedge (C. umhellata\ poverty grass {Danthonia spicataX and little blue stem grass (Schizachyrium scoparium). Other species typically encountered include rusty cliff fern {Woodsia ilvensis\ rock spikemoss (Selaginella rupestris\ early saxifrage {Saxifraga virgimensis\ arrow leaved violet (Viola sagittata), dry land bittercress (Cardamine parvijlora), skunk meadow-rue (Jhalictrum revolutum\ strawberry (Fragaria virginiana\ dwarf dandeUon (Krigia virginica\ pale corydalis {Corydalis sempervirensy, sleepy catch fly (Silene antirrhina\ Venus's looking gliiss {Triodanis petfoliata), blue curls (Trichostema dichotoma), several species of goldeiu-ods (Solidago bicolor, S. nemoralis) and other grasses (such as Aristida dichotoma.

The major threats are trampling and other uses by people. Succession appears to be proceeding slowly, if at all, on many of these sites. However, grazing and possibly fire may contribute to helping keep the areas. Most sites that are not too steep have evidence of deer browse..
Trails should be kept away from these areas because readily accessible sites are used as view-points and picnic areas. Planning of trails should take the fragility of the sites into consideration.
Sites supporting this community may be found along the Mohawk Trail (Rte. 2) in Shelbume and at Bardwell's Ferry in Shelbume but should probably be checked.

CALCAREOUS ROCKY SUMMIT / ROCK OUTCROP
CT2A1C0000
S2
Yes
Concept Environmental Setting:
An open community of shrubs and herbaceous plants occurring on open calcareous ridge tops of the low hills edging the valleys in the Western New England Marble Valleys eco-region as well as steep, mid- slope calcareous ledges found in the same region.
Ridge top calcareous outcrops are dry and typically are found on the ridge tops of low hills in the calcareous regions of Berkshire County. Their open aspect is maintained by trees uprooting and pulling away from the steep ridge top areas. Because, most calcareous bedrock in Massachusetts is overlain by more resistant acidic rocks, the community tends to be found on rock outcrops rather than actual rocky summits. The substrate grades from rock outcrops to steeper, but moister, shaded cliff faces wiiich support Calcareous Cliff Communities.
Vegetation Description: The ridge top community supports relatively sparse herbaceous vegetation that includes ivory sedge
(Carex ebumea), purple clematis (Clematis occidentalis\ long-leaved bluet {Hedyotis longifolia\ balsam groundsel (Senecio pauperculus) and lyre-leaved rock-cress (Arabis lyrata). Shrubs include round-leaved dogwood (Comus rugosa\ roundleaf shadbush (Amelanchier sanguinea) as well as the less common northern prickly rose (Rosa acicidaris), hairy honeysxickle (Lonicera hirsuta) and downy arrowwood (Viburnum rafinesquianum). Calcareous rock outcrop off the summit ridges tend to be moister and are Ughtly shaded by trees characteristic of rich mesic forests including sugar maple (Acer saccharumX white ash (Fraxinus americana),ai\d hop-hornbeam (Ostrya virginiana). The herbaceous layer can include species characteristic of rich mesic forests but typically has a high proportion of ferns such as bulblet fern (Cystopteris bulbifera\ fi^le fern (C. tenuis\ ebony spleenwort (Asplenium platyneuron\ maidenhair spleenwort (A. trichomanes), walking fern (Asplenium rhizophyllum) and blunt lobed wood fern (Woodsia obtusa) as well as the rarer ferns, purple cUff-break (Pellaea atropurpurea) and wall rue spleenwort (Asplenium ruta-muraria). Other plants that are frequently found on these ledges include ivory sedge (Carex ebumea), Pennsylvania sedge (Carex pensylvanica), harebell (Campanula rotundifolia), peduncled sedge (Carex pedunculata\ early saxifrage (Saxifraga virginiensis), lyre-leaved rock-cress (Arabis lyrata), smooth rock-cress (A laevigata), columbine (Aquilegia canadensis) and balsam groundsel (Senecio pauperculus).

Habitat Values for Associated Fauna:
Open, sparse herbaceous vegetation with little tree or shrub growth, generally under an acre in size; often with markedly different vegetation than in sun-ounding areas. Tree canopy is often only from surrounding forest: woody species growing on serpentine
Usually on small exposed ledges or outcrops of serpentine or other ultramafic [igneous rocks with high percentages of magnesium, often accompanied by iron, chromium and nickel] bedrock, or shallow soil over such bedrock. The soils derived from ultramafic rocks present unusual growing conditions that inhibits growth of many plants: low levels of necessary nutrients, relatively high concentrations of magnesium, and droughty conditions of thin soil over rock. Deeper soils derived from glacial deposits over serpentine, or ultramafic, bedrock do not support a serpentine outcrop community.
Large leaved sandwort (Moehringia macrophylla) is an absolute indicator of serpentine conditions, but does not occur in all locations. Field chickw^ (Cerastium arvense) is most abundant on serpentine outcrops, but also occurs in open woods on south -facing slopes. Serpentine areas typically are sparsely vegetated, have increased (relative to surrounding areas) dry adapted plants, and presence of some calcifiles. The vegetation is often a graminoid -savanna in larger occurrences (in Maryland, for example); in Massachusetts the occurrences are very small, and surrounding vegetation dominate most sites. In forest areas, white pine (Pinus strobus), hemlock (Tsuga canadensis), red maple (Acer rubrum.), red oak {Quercus rubra), and birches (Betula papyri/era and B. alleghaniensis) form a canopy, with witch-hazel (Hamamelis virginiana) in a sparse shrubs layer. Other associated species include bracken fern {Pteridium aquilinum), maidenhair spleenwort (Asptenium trichomanes) and grasses. Species considered somewhat calcifilic, such as columbine (Aquilegia canadensis), harebell (Campanula rotundifolia) and rock spike-moss (Selaginella rupestris) are sometime present
The Massachusetts serpentine areas are not large enough to affect larger herbivores, but small animals may be scarcer than normal. Plant cover is generally sparse, leading to less cover and food for animals. Porcupines are frequent in the canopy trees.

Habitat Values for Associated Fauna:
An open community of extremely sparse scattered vascular plants on ledges and in crevices within a sparsely vegetated vertical substrate of acidic rocks. Lichens are occasionally dense on the chfTface.
Acidic rock cliffs form on resistant bedrock. Little soil and few nutrients are available to support plants on the acidic cUff faces. Although often cooler and moister than Acidic Rocky Summits because of aspect or shading from surrounding forests, there is a continuum of conditions and Acidic Rock Cliff Communities may be physically below Acidic Rocky Summits and above Acidic Talus Slopes.
The vascular vegetation is sparse, the plant association not distinctive. Common polypody (Polypodium virginianum) and rusty cliff-fern {Woodsia itvensis) are often present in the crevices. Harebell (Campanula rotundifolia), bristly sarsaparilla {Aralia hispida), marginal wood-fern (Dryopteris marginalis\ fringed bindweed (Polygonum cilinode), stout goldenrod (Solidago squarrosd), and Virginia creeper (Parthenocissus quinquefolid) are common on acidic chffs, as well as in other sterile acidic conditions. Purple-flowering raspbeny (Rubus odoratus) occurs on acidic cliffs in the northern and western parts of the state. Trees from the surrounding forest may shade the cliff face; shaded cUffs have less vegetation than sunny occurrences. Surrounding forests are variable: oak forest, northern hardwoods, hemlock, or others throughout the state. Lichens may be abundant on the rock face. Cliffs are small areas within surrounding forest, and reflect the vegetation of the suiroimdings.
All types of cliffs provide nesting habitat for Ravens (Corvus corax) and, in the past. Peregrine Falcons (Falco peregrinus) nested on chffs before being extirpated from Massachusetts in 1955, and the Peregrine Falcons released in urban areas since 1 984 have not returned to the natural habitat, although they are breeding in the state. Cliffs were probably the native habitat of the Eastern Phoebe (Sayomis phoebe). No mammals, reptiles, or amphibians would be expected on the steep cliff faces.

Habitat Values for Associated Fauna:
Extremely sparse vegetation, in cracks and small ledges of nearly vertical cliff faces. A more diverse commxmity than found on Acidic Cliffs.
Vertical, or close to vertical, exposures of resistant limestone, dolomite, or other calcareous bedroclc; cliffs often include ledges and have talus slopes below. There is minimal soil development Surroundings tend to be northern hardwood forest, sometimes rich mesic forests. Calcareous rock outcrop and simunit commimities may occur above, although much calcareous rock in Massachusetts is overlain by more resistant acidic rock. The moister ledge commimities are usually mid-slope dolomite ledges or cUff faces with little soil.
The vegetation is distinct and specific to the habitat I*urple chff brake (Pellaea atropurpurea\ bulblet fem {Cystopteris bulbifera), maidenhair spleenwort (Asplenium trichomanes), blunt-lobed cUff-fem (Woodsia obtusa\ walking fem (Asplenium rhizophyllum\ and columbine (Aquilegia canadensis) are characteristic species of vascular plants. Bearberry {Arctostaphylos uva-ursi) and harebell (Campanula rotundifolia) grow in drier open sites, and moister, shaded sites have early saxifrage (Sadfraga virginiensis), rock-pellitory (Parietaria pensylvanica), small enchanter's nightshade (Circaea alpina\ and rock-cresses (Arabis hirsuta, A. lyrata, and A. laevigata). Lichen and moss grow on the rock face and in small cracks. Surrounding forest oflen includes sugar maple (Acer saccharum\ white ash (Fraxinus americana\ basswood {Tilia americana\ butternut (Juglans cinerea), and black and yellow birches (Betula lenta and B. alleghaniensis).

Concept
Environmental Setting:
Vegetation Description:
Associations:
Habitat Values for Associated Fauna:
Sparse, mostly herbaceous, vegetation limited to crevices where soil accumulates: only outcrops influenced by river processes are considered to be riverside outcrops.
The community occurs on flood scoured bedrock along rivers. The outcrops may be low or steep on the river's edge or extending into the river channel with alluvial soil accumulated in crevices in the rocks. Although regularly disturbed by almost annual flooding and ice scouring, river spray and proximity to water may alleviate some of the harsh conditions usually encountered on sand in open areas. Related to Riverside Seeps, which are distinguished by being wet most of the year.
Riverside rock outcrops support vegetation typical of other outcrops, low and scattered herbaceous plants; but also have fewer woody plants due to annual ice scouring. Typical plants include a mix of usually only a few species per site: included might be harebell (Campanula rotundifolia), Canadian bumet (Sanguisorba canadensis\ big blue stem (Andropogon gerardii), prostrate dogbane (Apocynum cannabinum var. hypericifolium\ goldenrods {Solidago spp.) or smooth, or riverside, rose {Rosa blanda). Nonnative species that commonly occur are Canada bluegrass (Poa compressa) and Purple loosestrife {Lythrum salicaria).
These small, exposed communities have few, if any, animals that are restricted to them. Shoreline foragers such as otter (Lontra canadensis\ mink (Mustela visonX and raccoons (Procyon lotor) would use rock outcrops as part of their overall habitat Turtles are not attracted to rocks, p-eferring to bask on logs. Occasional bull frogs (Rana catesbeiana) or northern water snake (Nerodia sipedon) would be expected. Common species of Dragonflies and tiger beetles hunt over the rock areas.

Habitat Values for Associated Fauna:
Several species of shorebird are beach specialist, nesting and foraging on beach strands, including Least Terns (Sterna antillarum). Piping Plover {Charadrius melodus), and American Oystercatcher (Haematopus palliatus) Beach strands are important shorebird staging areas: migratory shorebirds use barrier beach systems, including the beach strand community, for resting and congregating before and during migration. Merlins (Falco columbarius) and Peregrine Falcons (Falco peregrinus) forage on beaches during migrations. No amphibians or reptiles regiilarly occur on beaches. Few mammals use the beaches except for hunting by midsized predators such as red fox (Vulpes vulpes\ striped skunk (Mephitis mephitis\ and coyote (Canis latrans) and resting by seals (mostly Phoca vitulina). Invertebrate speciaUsts include several species of tiger beetles, beach flies, and, on the south side of the Cape, ghost crabs at their northern limit of distribution.

MARITIME DUNE COMMUNFTY
CT2B1B0000
S2
Yes
Concept:
Environmental Setting:
This is the classic commiinity of sand dunes, with patches of herbaceous plants inter^iersed with areas of bare sand and shrubs.
The maritime dune community occurs on windswept dunes, within the salt spray zone, often landward of the Beach Strand Community and grading into shrubland or woodlands on the more sheltered back dunes. Dunes are deposited by wind action or storm ovenvash. Wet areas between dunes are hiterdunal Swale Communities. Usually part of a barrier beach system. Ability of dunes to move is an important part of the habitat they provide.
Vegetation Description: Sand dimes characterized by expanses of beach grass {Ammophila breviligulata) with seaside goldenrod
{Solidago sempervirens\ beach pea {Lathyrus japonicus), and beach and golden heathers {Hudsonia tomentosa and H. ericoides). Shrubs such as bearberry (Arctostaphylos uva-ursiX bayberry (Myrica pensyhanica), lowbush blueberry (Vacdnium angustifolium), sweet fern (Comptonia peregrina), and beach plum {Prumis maritima) grow on protected slopes and some interdunal areas, mostly sparse, but becoming dominant to form shrublands. Poison ivy {Toxicodendron radicans) is often dense. Salt hay {Spartina patens), common hairgrass {Deschampsiajlexuosd), little blue stem {Schizachyrium scoparium\ and poverty grass {Danthonia spicatd) are common grasses of the community. Pinweed {Lechea ^p.X nutrush (Cyperus spp.) and sand jointweed (Polygonella articulata) grow mixed with Hudsonia. Scattered pitch pine (Pinus rigida) occur in some dune systems. Actual composition and structure of the vegetation depends upon recent dune stability (deposition and erosion) and distance from the ocean.
Associations:
Habitat Values for Associated Fauna:
A variety of seabirds shorebiids aivd song birds nest at the base and sides of dunes and in the interdunal area. The particular species depend upon topography, hydrologic regime, and the amount and type of plant cover. Vernal pools occur in some dune systems, serving as important feeding and breeding areas for a variety of reptiles and amphibians, invertebrates, and birds aad mammals. Diamondback terrapins {Malaclemys terrapin) use dunes for nesting. Northeastern Beach Tiger Beetles overwinter in the dunes.

The community grades into sandplain heathlands, shrublands, dunes, or forest It is maintained by fu"e, salt spray, and, now, mowing. It often occurs as small openings within Pitch pine / Scrub oak commimities.
Vegetation Description: Grasslands are dominated by graminoids, usually little blue stem grass {Schizachyrium scopan'um),
Pennsylvania sedge {Carex pensylvanica\ and poverty grass {Danthonia spicata), with bearberry (Arctostaphylos uva-ursiX scrub oak (Quercus ilicifolid), silff aster (lonactis linariifolius, formerly Aster linariifolius\ bayberry (Kiyrica pensytvanica), lowbush bluebeny {Vaccinium angustifolium), and black huckleberry (Gaylussacia baccata). Shrub clones often form patches. There is great ^)ecies overlap with sandplain heathlands, but sandplain grasslands are much richer in vascular species. As a group. Goat's rue (Tephrosia virginiana\ yeUow wild indigo (Baptisia tinctona\ butterfly weed (Asclepias tuberosa\ and bird's foot violet {Viola pedata) are good indicators of the commimity.
Dunwiddie dL al. (1996) recognized five grassland associations: Hairgrass Grasslands were divisible into a Beach Grassland subtype and a Heathy Grassland subtype and Little Bluestem Grasslands divided into Pennsylvania Sedge Grasslands, High Diversity Native Sandplain Grasslands, and Weedy Grasslands.
Animal species that are adapted to open areas include birds such as Grasshopper Sparrow (Ammodramus savannarum) which is particularly adapted to areas with ojsen ground between grass tussocks and Eastern Meadowlaiks (Stumella magna) which uses areas with continuous short grass. Small mammals include meadow vole (Kiicrotus pennsylvanicus\ meadow jumping mouse (Zapus hudsonius), and short- tailed shrew (Blarina brevicauda). Grasslands p-ovide hunting territory for hawks and owls. Black racers {Coluber constrictor) are common snakes that also live and hunt in open grasslands.

Environmental Setting:
This distribution map focussed on cultural grasslands occurring on sandplains.
A human created and maintained open community dominated by grasses, normally maintained by mowing; primarily of conservation interest for the grassland bird commimity.
A grassland community that generally occurs on sand or other droughty, low nutrient soils. Surroundings, in many areas include Pitch pine / Scrub oak communities. Many small airports with surrounding grasslands were built on sand plains. Pastures and hayfields occur in all areas, and surroundings reflect the regional variations.
Vegetation Description: Airports, cemeteries, pastures, and hayfields provide different habitats, and support different species of
plants and animals. Grasslands at many smaller airports are dominated by graminoids, usually little blue stem grass (Schizachyrium scoparium), Pennsylvania sedge {Carex pensylvanicd), and poverty grass (Danthonia spicatd), and many non-native species. Some cultural grasslands do have some mix of herbaceous ^)ecies, such as goldenrods {Solidago and Euthamia spp.) and milk weeds including butterfly weed (Asclepias spp. and A tuberosa).
Associations:
Habitat Values for Associated Fauna:
Grasslands at airports tend to have more native grasses than do Oelds that are, or were recently, cultivated. Cemeteries are variable, some older ones have more native species than do more actively managed, newer cemeteries. Most cultural grasslands are mowed at least annually to maintain the grassland stage. Hayfields have fewest native species, but do support grassland birds.
Distance to the coast and size of the grassland strongly affect the species that use a grassland. Many species of birds that use grasslands are more common in the midwestem prairies and agricultural fields. Airports currently support Massachusetts' largest populations of Upland sandpipers {Bartramia longicauda). Grasshopper Sparrows {Ammodramus savannanun), and Savannah Sparrow (Passerculus sandwichensis). Other grassland birds are found in different habitats - such as Bobolinks {Dolichonyx oryzivorus) in hayfield length taller grass. Eastern Meadowlarks (Stumella magna) in jsasture length short grass. Other grassland birds include Killdeer {Charadrius vociferus\ Northern Meadowlarks {Stumella magnaX and Homed Larks (Eremophila alpestris). Meadow voles (Microtus pennsylvanicus\ meadow jumping mouse {Zapus hudsonius), and the northern short-tailed shrew (Blarina brevicaudd) would be expected in most grasslands. They would be hunted by garter snakes (Thamnophis sirtalis\ long-tailed weasels {Mustela frenata). Kestrels {Falco sparverius), and wintering Northern Harriers (Circus cyaneus). Snowy Owls {Nyctea scandiacaX and Short-eared Owls (Asio/lammeus).

Habitat Values for Associated Fauna:
An open, shrub dominated, primarily coastal community, sharing many species with Sandplain Grasslands. Heathlands often have sparse clumps of plants with bare soil or lichen cover between the vascular plants.
Heathlands occur on acidic, nutrient poor, droughty soils. Sandplain heathlands grade into Sandplain Grasslands, and both grade into other coastal communities such as Maritime Shrublands, Scrub Oak Shrublands, and Pitch Pine/Scrub Oak Communities, where they often occur in openings. Natural occurrences were likely maintained by fire and / or salt ^ray.
Many of the dominant species in heathlands are woody: scrub oak (Quercus ilicifolia\ black huckleberry (Gaylussacia baccata\ bearberry (Arctostaphylos uva-ursi\ and lowbush blueberry {Vaccinium angustifolium). Other characteristic species include hairgrass {Deschampsiaflexusoa\ Pennsylvania sedge {Carex pensylvanica\ little blue stem {Schizachyrium scoparium\ stiff aster (lonactis linariifolius, formerly Aster linariifolius), bayberry (Myrica pensylvanica\ golden heather (Hudsonia ericoides), chokeberry (Aronia arbutifolia), dwarf chinqu^in oak {Q. prinoides), and sweetfem (Comptonia peregrina). Heathlands are less species rich than grasslands and appear taller. The tall shrublands association particularly includes non-ericaceous tall shrubs such as beaked hazelnut {Corylus comuta\ befich plimi (Prunus maritima\ and dewberry (Rubus flagellaris). The species overlap with grasslands is great: it is the proportion of the species and the resultant structure that separates the communities. The communities are not distinct at some sites.
Dunwiddie et al. 1996 recognized two large heathland associations: Tall shrub, which subdivides into Mixed Maritime Shrubland and Huckleberry - Scrub Oak Heathlands, and Low shrub, which divides into Broom Crowberry Heathlands and Bearberry Heathlands. A somewhat depauperate type of heathland developed on dredge spoils foxmd along the Cape Cod Canal, and could be considered a cultural subtype of heathland community.
Homed Lark (Eremophila alpestris\ Savannah Sparrow (Ammodramus savannarum\ and Vesper Sparrow (Pooecetes gramineus) use sandplain heathlands. Northern harriers (Circus cyaneus) nest in heathlands or nearby shrublands and hunt in grasslands and open heathlands. Meadow voles (Microtus pennsyhanicusX short-tailed shrews {Blarina brevicauda\ and white -footed mice (Peromyscus leucopus) are often abundant near or under the shrubs. White-footed mice are known to be hosts of the deer tick (Ixodes scapularis) that carries Lyme Disease. Other invertebrates of Heathlands includes butterflies such as Hairstreaks and Skippers.

Shrub community, dominated by patches of dense shrubs with scattered more open areas of low growth or bare ground.
Coastal, within the area receiving storm salt spray, but out of the normal range of daily salt spray. Occurs on rocky headlands or behind dunes in protected areas of barrier beaches.
Often dense patches of shrub, with various species dominating in different areas. Huckleberry {Gaylussacia baccata), bayberry {Myrica pensylvanica\ or red cedar (Junipenis virginiana) areas are often distinctive. Black cherry (Pruntis serotina\ beach plum {Pnmus maritima\ chokeberry {Aronia melanocarpa), low bush blueberry (Facc/n/Mm angustifolium\ and bearberry (Arctostaphylos uva-ursi) may be abundant Catbrier (Smilax rotundifolia) and poison ivy (Toxicodendron radicans) often cover other plants or grow in dense patches on their own.
Two variants: rocky headlands and on dunes, need to be field checked to see how different they are from each other.
Shrub thickets provide nesting areas for Northern Harriers (Circxts cyaneus). Northern Towhee (Pipilo erythrophthalmus\ and Song Sparrows (Melospiza melodia). Maritime shrublands are heavily used during fall migrations for cover and forage — many of the plants have fruit attractive to migrants. White- tailed deer (Odocoileus virginiamis) maintain large populations in shrubland habitats. In such shrub areas, white-footed mice {Peromyscus leucopus) are also very abundant, and in the openings meadow voles {Microtus pennsylvanicxis) are common. Eastern moles (Scalopus aquaticus) have an affinity to the sand substrate in the southern part of the state. Long-tailed weasels (Mustelafrenata) occur in the grass dominated areas where they hunt meadow voles. Eastern hognose snake (Heterodon platirhinos) occur in sandy, open areas of shrubland communities areas.

Habitat Values for Associated Fauna:
Scattered pitch pines on active sand dunes, many with trunks at least partially buried. Open canopy with bare ground and scattered shrubs, herbaceous plant, and patches of lichen.
The community occurs on moderately stabilized back dunes where storms produce active sand movement. The areas receive salt spray during storms and strong winds, but not on a daily basis.
Short, scattered individuals of Pitch pine (Pinus rigida) dominates the tree layer. Open sand has scattered beach heather {Hudsonia tomentosa\ bearberry {Arctostaphylos %iva-ursi\ and patches of lichen.
There are no animal species known to be restricted to maritime forests. The open Pitch Pine areas are particularly harsh and exposed, and support fewer animals than more closed communities. Generally, in more salt influenced environments, fewer animals will be expected. As in all commimities on peninsulas such as Cape Cod, or on islands, the more remote occurrences have fewer ^)ecies than those closer to the mainland sources. Moths, butterflies, and other insects of the southeastern oak-pine forest occur in maritime forests.

Predominantly evergreen woodland / shrubland within the coastal salt spray zone. The trees tend to be short (less than 5 m ^about 15 feet)) and scattered. Tops of trees and shrubs are sculpted by winds and salt spray.
Maritime communities occur along the coast within the area of direct influence of the ocean and salt spray, but not in areas flooded by salt water. They are usually somewhat protected fi-om direct spray by crests of dunes Juniper dominated maritime communities tend to occur on sand of interdunal areas, backs of dunes, and exposed blufis, and also on salt marsh borders, and, to a lesser extent, on rocky headlands.
Trees are usually short relative to interior forests. The Maritime Juniper Woodland / Shrubland community occurs as part of continua of sparse shrubland to forest, and deciduous to evergreen dominants, in areas of continuous changes of levels of salt spray and substrate types. Virginia juniper, also called red cedar (Juniperus virginiana) dominates but occurs in variable, usually low, densities in association with scattered trees and shrubs typical of the surrounding forest such as Pitch pine {Pinus rigida), various oaks (Quercus spp.\ American holly (Ilex opaca), black cherry (Prunus serotina), red maple (Acer rubrum\ bayberry (Kfyrica pensylvanica) and winged sumac (Rhus copallinum). The herbaceous layer is highly variable, with little blue stem grass (Schizachyrium scoparium), beach grass (Ammophila breviligulata), and sedges, often with scattered beach heather (Hudsonia tomentosa). Microtopography and local conditions strongly influence the species assemblage.
There are no animal species known to be restricted to maritime woodlands. Animal species are those of typical coastal oak areas such as the birds Rufous-sided Towhees (Pipilo erythrophthalamus). Gray Catbirds (Dumetella carolinensis). Common Yellowthroats (Geothlypis trichas\ Ovenbird (Seiurus aurocapillus) and Black-and-\\iute Warbler (Kiniotilta varia). Small mammals such as meadow voles (Microtus pennsylvanicus\ white footed mice (Peromyscus leucopus)^d gray squirrels (Seiurus carolinensis) are common in Massachusetts' forests. Moths, butterflies, and other insects of the southeastern oak and oak-pine forest occur in maritime forests. Generally, in more salt influenced environments, fewer animals will be expected. As in all communities on peninsulas such as Cape Cod, or on islands, the more remote occurrences have fewer species than those closer to the mainland sources.

Vegetation Description:
A shrubland dominated by scrub oak, with essentially no pitch pine, although within pitch pine - scrub oak areas.
Scrub oak shrublands occur within pitch pine / scrub oak communities, particularly in frost bottoms and frost pockets, and on ridge tops near ridge top pitch pine / scrub oak communities. They are part of a mosaic in space and time of grassland and heathland openings, shrublands, pitch pine / scrub oak communities, and oak / pine forest The shrublands are to some extent maintained by late spring and early fall frosts damaging more susceptible competing tree species.
Scrub oak (Quercus ilicifolia) and dwarf chinquapin oak {Q. prinoides) dominated shrublands, with a variety of other heathland plants, including a significant component of graminoid cover and interspersed with patches of hchen. Characteristic plants besides scrub oak are huckleberry {Gaylussacia baccata), low bush blueberry {Vaccinium angustifolium\ Peiuvsylvania sedge {Carex pensylvanicd), little bluestem grass {Schizachyrium scoparium\ and lichens {Cladina and Cladonia spp).

Shrub dominated communities with scattered to dense trees and scattered openings. Shrubs are often very dense.
Pitch pine/scrub oak communities develop on droughty, low nutrient soils - usually deep, coarse, well- drained sands derived from glacial outwash — in the coastal plain, the Connecticut River Valley, and other scattered areas throughout the northeast Pitch pine/ scrub oak communities are a fire maintained and fire dependent community; most species in the community recover well from fire. The openings grade into heathland and grassland communities, wiuch are larger. The commimity grades into Pitch pine - oak - heath forests which have tree oak species and much less scrub oak, and usually occur in less dry environments.
Pitch pines fonn an open canopy above a shrub layer domirated by shrub oaks, scrub oak (Quercus ilicifolia) and sometimes dwarf chinqu^in oak {Q. prinoides). Older oaks may form a nearly impenetrable understory 3-4 m {10- 1 5 feet) tall, or it may be more open and shorter. Huckleberries (Gaylussacia baccata) occur between the oak clones or under more open plants. Scattered openings of variable size support patches of heathland or grassland vegetation — more or less s{)arse lowbush blueberry (Vaccinium angustifolium\ bearberry {Arctostaphylos uva-ursi\ lichen patches, little bluestem grass {Schizachyrium scoparium\ sedges {primarily Carex pensylvanica and C. rugosperma), and beach heather (Hudsonia tomentosa). Cow \viieat {Melampyrum lineare) and mayflower (Epigaea repens) are typically found on edges within the commimity.
Inland variants on sand of the Pitch Pine/ Scrub Oak Community tend to have more gray birch (Betula populifolia), trembling aspen (Populus tremuloides) and black cherry (Prunus serotind) and pin (or fire) cherry {Prunus pensylvanica). A related community, Ridgetop Pitch Pine / scrub oak community occurs on b»d rock ridge tops across the state. Maritime Pitch Pine on EXmes has little scrub oak and is much sparser. Pitch pine over sedges with scattered heath species usually develops on previously plowed soils.
A large number of species of lepidopterans are restricted to the pitch pine/ scrub oak community, and its openings. The bird fauna is generally that of oak woodlands: Rufous -sided Towhee {Pipilo erythrophthalmus). Pine Warbler {Dendroica pinus\ and ruffed grouse {Bonasa umbellus) are common. Whii>-poor-will {Caprimulgus vociferus) and Common Nighthawk {Chordeiles minor) are now increasingly restricted to sandy openings of pitch pine / scrub oak communities. American woodcock {Philohela minor) also use the openings.

Concept:
Environmental Setting:
Vegetation Description:
Ridgetop pitch pine-scrub oak woodland occurring on acidic bedrock, often occurring in a mosaic with Acidic Rocky Summit / Rock outcrop Communities.
This community, tolerant of extremely xeric growing conditions, is foxmd on ridge tops and exposed outcrops of acidic bedrock (including schists, gneiss, granite and quaitzite), ranging in elevation (in Western Massachusetts) from 255 to 792 meters. Aspect may range from N to S along ridgetops, but in general the most typical examples have a south to southwest aspect, and are found on level crests as well as steep slopes and receive high solar insolation. Soil accumulation is slow and soil depths are generally shallow, often with considerable exposed bedrock. Communities are fire dependent— where fire has been infreqxient, succession to white pine-oak forest is evident
Ridgetops and steep upper mountain slopes with an open to closed canopy of pitch pine {Finns rigida). Soils are thin, in places consisting only of a thin layer (2 cm) of duff and decomposed leaves over bedrock, ranging to several centimeters of sandy, rocky very well drained soil. The woodland canopy characteristically contains somewhat dwarfed pitch pines (ovg. 5 m talF), with scattered taller trees including red oak (Quercus rubra\ black oak {Q. velutina\ rock chestnut oak {Q. montana) and scarlrf oak {Q. coccinea). Gray birch {Betula tremu hides), and hickories (Carya spp.) are occasionally present in the canopy or subcanopy. Rarely, one may find red pine (Pimis resinosa) White pine (Pinus strobus) may dominate the canopy in areas that have not experienced regular fire disturbance. The imderstory is patchy, and often interspersed with large areas of exposed bedrock. Shrubs commonly include blueberry (Vaccinium angustifolium and^or V. pallidum), scrub oak {Quercus ilicifolia), and huckleberry {Gaylussacia baccata). Chinquapin oak {Quercus prinoides) is occasionally present Herbs are sparse and may include Canada mayflower {Maiandiemum canadense), bastard toad-flax (Comandra umbellata), cow wheat {Melampyrum lineare), tall corydalis {Corydalis sempervirens\ black chokeberry {Aronia melanocarpa), goldenrod {Solidago spp.), and at higher elevations, mountain white potentilla {Potentilla tridentata\ and bearbeiry, {Arctostaphylos uvo-um). Variants: A related pitch pine ridgetop community, usually lacking scrub oak, has an herbaceous layer dominated by hairgrass {Deschampsiaflexuosa) or poverty oats {Danthonia spicata). Another variation of acidic rocky ridgetop includes a shrub community dominated by scrub oak, with a similar complement of heaths and herbs, but lacking pitch pine. Pitch pine-scrub oak ridgetop communities may occur in patches with grassy balds. Acidic Rocky Summit / Rock Outcrop Communities, lacking pitch pine and scrub oak. These small balds usually have a more diverse herb layer.

Small slopes may have closed canopy coverage from surrounding trees.
Talus derived from Eicidic bedrock. Ground cover is exposed talus, moss or lichen covered boulders, and deciduous litter. Community develops on dry to mesic, loose rocky slopes often below cUffs or rock outcrops. Forest grades into surrounding forests which are usually taller and more diverse. Open talus areas are drier, and rocks covered by lichens.
The canopy is formed by a mix of species including red oak (Quercus rubra), sugar maple (Acer saccharum\ black birch (Betula lenta\ yellow birch {B. alleghamensis\ paper birch (B. papyriferd), gray birch {B. populifolia\ red maple (Acer rubrum), beech (Fagus grandifoliaX hemlock (Tsuga canadensis), and white pine (Pinus strobus).

Habitat Values for Associated Fauna:
Mixed deciduous/evergreen forest/woodland within the coastal salt spray zone. The trees tend to be short, less than 10 m [about 30 feet].
Maritime forests occur along the coast within the area of direct influence of the ocean and salt spray, but not in areas flooded by salt water. They occur on exposed bluffs, backs of dunes, interdunal areas, salt marsh borders, and rocky headlands. Tree tops are sculpted by winds and salt spray. They are best developed where somewhat protected from direct spray by crests of dunes.
Trees are usually short relative to interior forests. Scarlet oak (Querctis coccinea), black oak {Q. velutina), other oaks, American holly (Ilex opaca\ sassafi-as (Sassafras albidum), black gum (Nyssa sytvaticaX black cherry (Prunus serotina\ and red maple (Acer rubrum) are commonly present. Pitch pine (Pinus rigida) and red cedar (Juniperus virginiana) occur in variable amounts. Vines may be dense especially on the edges of openings; dominants include GreentHier (Smilax rotundifolia) and poison ivy (Toxicodendron radicans), Virginia creeper (Parthenocissus quinquefolid) and/or grape (Fin.s aestivalis). Shrubs include bayberry (Myrica pensylvanica), winged simiac (Rhus copallinum) and sweet pepper-bush (Clethra alnifolia). The herbaceous layer is highly variable, and may include grasses and sedges. Microtopography and local conditions strongly influence the ^)ecies assemblage. Low (but not as wet as swales) interdunal areas oflen include species of wetlands such as azaleas (Rhododendron spp.), viburnums (Viburnum spp.), winterbeny (Ilex verticillata), and high bush blueberry (Vaccinium corymbosum). The herbaceous layer of these wetter areas sometimes includes species usually associated with rich, moist sites, such as columbine (Aquilegia canadensis), starry Solomon's seal (Kiaianthemum stellatum\ and skmik meadow-rue (Thalictrum revolutum).
There are no animal species known to be restricted to maritime forests. Animal species are those of typicfd coastal oak areas such as the birds Rufous-sided Towhees (Pipilo erythrophthalamus). Gray Catbirds (Dumetella carolinensis). Common Yellowthroats (Geothlypis trichas\ Ovenbird (Seiurus aurocapillus) and Black-and-white Warbler (Mniotilta varia). Small mammals such as meadow voles (Microtus pennsylvanicus\ white footed mice (Peromyscus leucopusXand gray squirrels (Seiurus carolinensis) are common in Massachusetts' forests. Moths, butterflies, and other insects of the southeastern oak aiKi oak-pine forest occur in maritime forests. Generally, in more salt influenced environments, fewer animals will be expected. As in all communities on peninsulas such as Cape Cod, or on islands, the more remote occurrences have fewer species than those closer to the mainland sources.

Concept: Coastal forests are oflen shorter than forests further inland, but taller tlian maritime forests. There is
often a dense shrub layer and vines, particularly near the edges.
Environmental Setting: Communities are found in more protected areas along the coast, sach as behind dunes and on slopes
away from the water, and behind maritime forests. Coastal forests are sheltered from direct daily maritime influences [not in tl^ daily salt spray zone, but receive wind and salt during storms]. The community occurs within the climate area moderated by being near the ocean, with warmer winters and cooler summers than more inland areas. Although they oflen occur on sand or bedrock that doesnt hold water, fogs and increased precipitation can produce more available water than further inland. Historically, fire was often an important factor in coastal forests. Coastal and maritime forests and m£uitime shrublands grade into each other, and into dunes and more inland forests.
Vegetation Description: Tree oaks (scarlet oak (Quercus coccinea\ black oak (Q. velutina), wiiite oak (Q. alba) and chestnut oak
(Q. prinus)) are the dominant species of the coastal forest, with post oak (Q. stellata) important in the Buzzard's Bay and Island areas. Red maple {Acer rubrum\ sassafias (Sassafras albidum), black cherry (Prunus serotina), tupelo (Nyssa jy/va/jcaXbeech (Fagus grandifoUaX pitch pine (Pinus rigidaX and white pine (Pinus strobus) commonly occur, usually in low percentages, but occasionally abundant American Holly (Ilex opaca) is a regular associate in the southeastem Massachusetts occurrences of the coastal oak forest (where holly is abundant, the association may be called a coastal oak / holly forest). Red cedar (Juniperus virginiand) occurs in low percentages in the forests, and sometimes as a dominant in woodland thickets. A low-shrub heath layer dominated by low bush blueberries (Vaccinium pallidum, V. angustifolium) and black huckleberry (Gaylussacia haccata) is very characteristic. The herbaceous layer is typically sparse, with Pennsylvania sedge (Carex pensylvanica\ bracken fern (Pteridium aquilinum\ wintergreen (Gaultheria procumbens) aivd wild sarsaparilla (Aralia nudicaulis) being typical. Sweet pepper-bush (Clethra alnifolia), surprisingly, is abundant in many sites. Openings in the canopy produce a greater diversity of the herbaceous layer, where little blue-stem grass (Schizachyrium scoparius), Canadian rockrose (Helianthemum canadense\ bush clovers (Lespedeza spp.), milkworts (Lechea ^p.) and bearberry (Arctostaphylos uva-ursi) occur. Most occurrences of coastal forests have many vines on the edges and in openings of the forest Poison ivy (Toxicodendron radicans), Virginia creeper (Parthenocissus quinquefolia\ grape (Vitis spp.X and greenbriers (Smilax ^p.) can be locally abundant.

Habitat Values for Associated Fauna:
Dry oak / pine forest and woodlands of moraines, till, outwash, southerly exposures, and rocky slopes. Matrix forest of southeastern Massachusetts. The proportions of different species are variable, and range from predominantly pine with scattered oaks to predominantly oak with scattered pmes. The structure ranges from open canopy with a thick understory, to closed canopy with scattered clumps of shrubs.
Dry, low nutrient, acidic soils of moraines and rocky slopes, also less distiirbed sandplains, inland away from regular oceanic influences. Pitch pine - oak forests surround coastal plain ponds, pitch pine / scrub oak communities, and grade into coastal forests towards the ocean. The commimity is fire dependent, supporting increased white pine (Pinus strobus) and red maple (Acer rubrum) as time since the last fne increases. The time since fire or other disturbance is likely to be a factor in the jx"oportion of pitch pine to oak.
Pitch pine - oak forests have a canopy of pitch pine and tree oaks (black (Quercus velutina\ scarlet (Q. coccinea\ chestnut oak (Q. prinus), and white (Q. alba)\ with blueberries (Vaccinium angustifolium and V. pallidum\ black huckleberry (Gaylussacia baccata) and other ericaceous shrubs forming an often continuous low shrub layer. Scattered patches of Scrub oak {Quercus ilicifolia) and bear oak {Q. prinoides) can be dense. Catbriar and other briars (Srmlax rotundifolia and Smilax ^p.) often make dense barriere around low, damp openings. The herb layer is generally sparse, with bracken fern {Pteridium aquilinum), wild sarsaparilla (Aralia nudicaulis\ wintergreen {Gaultheria procumbens), Pennsylvania sedge {Carex pensylvanica\ and, less commonly, pink lady's slipper (Cypripedium acaule). Oxasional white pine (Pinus strobus) and red maple (Acer rubrum) contribute to the canopy.
Part of a continuum of dry, acidic commimities that contain a variety of tree oak and pine species. More work is needed to defme types.
Supports many common and listed moths dependent on the oak and pine. The bird fauna is similar to that of oak woodlands: Rufous-sided Towhee (Pipilo erythrophthalmus\ Pine Warbler (Dendroica pinus), and ruffed grouse (Bonasa umbellus) are common. Most common mammals of Massachusetts have at least part of their habitat in pitch - pine oak forests and none are particularly characteristic, [proposed for listing 2000, Orange Sallow Moth (Rhodoecia aurantiago) T\

Concept: Environmental Setting:
A forest of mixed dominance with oaks and vviiite pine in the canopy.
On moraine or till, often dry but not very dry. Grades into I*ine - Northern Hardwood to the north. In southern areas occurs near pitch pine • oak forests, and grades into them. Often in a successional sequence from successional white pine forests. Also grades into mixed oak forests. In southeastern areas overlaps with Coastal Forest types: White pine - oak - holly and white pine - oak - beech forests.
Vegetation Description: White pine (Pinus strobus) and oak species (Quercus rubra, Q. velutina. Q. alba, Q. coccinea, and Q.
prinus) dominate the canopy layer in a variety of proportions. Pitch pine {Pinus rigida\ red maple {Acer rubrumX white birch {Betula papyri/era) and black birch {B. lenta\ occur regularly but in low numbers. Southern areas also have pignut hickory {Carya glabra) and Sassafras {Sassafras albidum). Chestnut {Castanea dentata) is frequently present as a shrubby tree. Usually has a prominent heath shrub layer, with lowbush blueberries {Vaccinium angustifolium and V. pallidum\ huckleberry {Gaylussacia baccata), mountain laurel {Kalmia latifolia), sheep laurel {K. angustifolia). Other shrubs include maple- leaved viburnum {Viburnum acerifolium). Characteristic species of the sparse herb layer include bracken fern {Pteridium aquilinum\ wild sarsaparilla {Aralia nudicaulis), Canada mayflower {Maianthemum canadense\ wintergreen {Gaultheria procumbensX partridge-berry {Mitchella repens\ pink lady's slipper {Cypripedium acaule), cow-wheat {Kielampyrum lineare), and whorled loosestrife {Lysimachia quadrifolia).

OAK - HEMLOCK - WHITE PINE FOREST
CTIBIOOOOO
ss
No
Concept:
Environmental Setting:
A mixed conifer - hardwood forest normally occumng in the southern part of the state, often on dry, acidic slopes.
Common on midslopes on rocky, shallow well-drained soils, with few nutrients. The dry oak -hemlock - white pine community is not sensitive to aspect. The community grades into northern hardwood - hemlock- white pine forests to the north and on moister sites, which typically have more hemlock. To the south and on drier sites, wiiite pine - oak forest and mixed oak forest become more common.
Vegetation Description: Oaks (Quercus alba, Q. prinus, Q. rubm), black birch (Betula lenta\ black cherry (Prunus serotina\
and red m^le {Acer rubrum) in association with hemlock (Tsuga canadensis) and white pine (Pinus strobus). Relative proportions of the ^lecies vary greatly among sites. Beech (Fagtis grandifolia) is a common associate, and chestnut (Castanea dentata) sprouts are common. The shrub layer is patchy and sparse, with witch-hazel (Hamamelis virginiana\ mountain laurel {Kalmia latifolia\ lowbush blueberry {Vaccinium angustifolium\ and maple-leaved viburnum (Viburnum acerifolium) characteristically present. The herbaceous layer also tends to be sparse and with little diversity: Indian cucumber {Medeola virgimana\ wintergreen {Gaultheria procumbens\ wild sarsaparilla {Aralia nudicaulis\ wild oats (Uvularia sessilifolia\ star flower (Trientalis borealis), and Canada Mayflower (Maianthemum canadense) are typical.

Habitat Values for Associated Fauna:
May be on the moister end of the continuum of dry, acidic commxmities that contain a variety of tree oak and pine species. More work is needed to define types.
The fauna of this community is richer than but overlaps with that of the mixed oak commimities. There is a large suite of neotropical migrant birds that are more likely to be foimd here, in some of the larger sites, including about 15-16 warblers. Eastern Wood-Pewee (Contopus virens\ and Great Crested Flycatcher (Miarchus crinitus). Where mountain laurel occurs with beech trees. Black-throated Blue Warblers (Dendroica caerulescens) may occur, and if there are low spots with large trees aiKl fairly dense shrubs, Canada Warblers (Wilsonia canadensis) often occur. In large sites, large mammals, such as bear and moose, occur with the forest as part of their habitat Common small mammals include smoky shrew (Sorexfumeus), masked shrew (5. cinereus), short-tailed shrew (Blarina brevicauda\ woodland jumping mouse (Napaeozapus insignis\ white-footed mouse (Peromyscus leucopus), and gray squirrels (Sciurus carolinensis\ chipmunks (Tamias striatusX arvi red squirrels (Tamiasciurus hudsonicus), where hemlock are dominant. Amphibians would mclude the ubiquitous Northern Redback Salamanders (Plethodon cinereus) and red efts, the juvenile stage of red-^x)tted newts (Notophthalmus V. viridescens).

Abandoned agricultural land, usually pasture. Sometimes selective logging maintains the pine as a dominant
White pine (Pinus strobus) dominated forest, with scattered white oak (Quercus alba), red oak {Quercus rubra\ and red maple {Acer rubrum) in the canopy. The shrub layer is variable density, from sparse to thick: Elderberry (Sambuais canadensis), black cherry (Prunus serotina\ maple-leaved vibumimi {Viburnum acerifolium), and often non-native species such as buckthorn {Rhamnus frangula\ honeysuckle (Lonicera morrowii), or/and multiflora rose (Rosa multijlora). A variety of blackberry vines (often forming thicketsX and poison ivy {Toxicodendron radicans) often covers the ground near openings or in formerly open disturbed areas. Low bush blueberries {Vaccinium angustifolium and V. pallidum) form patches, mixed with black huckleberry {Gaylussacia baccata), on sites with less disturbed soils. The herbaceous layer is variable; large patches of Canada mayflower ( Kiaianthemum canadensis\ and starflower {Trientalis borealis) with clubmosses {Lycopodium obscurum and related species) are particularly common on formerly plowed soil. Bracken fern {Pteridium aquilinum) is often common. Partidgeberry (Mitchella repens), fringed polygala {Polygala unijlord), and pink lady slipper {Cypripedium acaule) grow in many longer est^lished sites.

OAK - HICKORY FOREST
CT1B2B0O00
S4
No
Concept: A hardwood forest dominated by a mixture of oaiu >vith hickories mixed in at a lower density.
.Environmental Setting: Well drained sites, such as ui^)er slof)es, ridgetops, usually with west and south -facing aspects.
Vegetation Description: A broadly defmed, variable, forest type. The canopy is dominated by one or several oaks (Quercus
rubra, Q. alba, Q. coccinea, and Q. velutina). Mixed in are lower densities of one or several hickories (Carya ovata, C. tomentosa, C. glabra, and C. ovalis). Other trees include with ash (Fraxinus americana\ black birch (Betula lenta\ sassafras (Sassafras albidunt), and red maple (Acer rubrum). A subcanopy commonly includes hop hornbeam (Ostrya americana), flowering dogwood (Comus florida\ shadbush (Amelanchier arborea\ chestnut (Castanea dentata), and witch-hazel (Hamamelis virginiana). Low shrubs are common and often diverse: maple-leaved vibumimi (Viburnum acerifolium), blueberries (Vaccinium angustifolium and V. pallidum\ beaked and American hazelnut(Cor>'/«j comuta and C americana). New Jersey tea (Ceanothus americanus\ and gray dogwood (Comus racemosa) are characteristically present The herbaceous layer is also richer than in many oak forests. Plants typical of the herbaceous layer include Hepatica (Hepatica nobilis\ goldenrod (Solidago bicolor\ tick-trefoil (Desmodium glutinosum and D. paniculatum), wild sarsaparilla (Aralia nudicaulis\ rattlesnake weed (Hieracium venosum\ and false Solomon's seal (Kiaianthemum racemosa\ and Peimsylvania sedge (Carex pensylvanica).
Associations:
Habitat Values for Associated Fauna:
Part of a continuum of dry, acidic communities that contain a variety of tree oak and pine species. More work is needed to defme types. Hickory is seldom dominant enough to wan^nt being part of the name.
Wild turkey (Kfeleagris gallopavo) are foimd in primarily oak areas. Dry oak forests support a smaller mix of animal species than are found in moister communities. There are no species known to be restricted to the Oak Hickory Forest community. Common species of dry sites include short-tailed shrew (Blarina brevicauda\ red-backed vole (Clethrionomys gapperiX white footed mouse (Peromyscus leucopus\ and chipmunks (Tamias striatus). Snakes of dry forest sites include garter snakes (Thamnophis s. sirtalis) and redbelly snakes (Storeria o. occipitomaculata). Birds that nest in oak forests include Eastern Wood-Pewee (Contopus virens\ Red-eyed Vireo (Vireo olivaceus\ Scarlet Tanager (Piranga olivacea), and Ovenbiid (Seiurus aurocapillus).

Mixed hardwood, open forests with a sparse shrub layer. A nearly continuous cover of graminoids includes a rich diversity of herbaceous flora.
Occurrences of the community are usually small (a few acres), on thin, well drained soils, generally in midslope on southern or eastern exposures below balds and rock outcrops on traprock ridges. The community occurs as pockets separated by oak forests growing on deeper, moister soils in erosion channels. There is great variation in environmental conditions among sites.
Hickory - hop hornbeam communities are fairly open forests dominated by a variable mixture of hardwoods, including sugar maple (Acer saccharum\ white ash (Fraxinus americana\ and red oak {Quercus rubra), Shagbark, pignut and Sweet pignut hickories {Carya ovata, C. glabra, and C. ovalis\ and Hop-hornbeam (Ostrya virginiana) as a regular and abundant subcanopy tree. The forest floor is characteristically covered by Pennsylvania sedge {Carex pensyhanicd), other sedges (C. pedunculata and C. laxijlorae spp\ and grasses such as bottlebrush grass (Elymus hystrix\ Poverty grass (Danthonia spicata) and the non-native Canada bluegrass {Poa compressa) with scattered violets {Viola triloba), hepaticfis (Hepatica nobilis var. obtusa), and several species of tick-trefoils (including Desmodium glutinosum and D. paniculatum).
These are small community occurrences, and tend to be part of the habitat of species using the surroimding forests. Species of dry sites are most likely to occur in the community occurrences.

Concept: Environmental Setting:
A dry, often open, oak - siigar maple forest with rich understory on shallow rock.
Well - drained slopes or low ridges underiain with calcareous rocks. The community tends to be more abundant in southern parts of the calcareous areas of the state (Berkshire County\ and is more restricted to south and southwest facing slopes in more northern parts of Berkshire Coimty.
Vegetation Description: Yellow oak (Querais muehlenbergif) is characteristic of this community, and primarily occurs in it in
Massachusetts. It grows mixed with sugar maple (Acer saccharum\ white oak (Q. alba) and black oak (Q. velutina), and associated with white ash (Fradnus americana) and shagbark hickory (Carya ovata). Scattered white pines (Firms strobus) and red oak (Q. rubra) occur regularly Hop hornbeam (Ostrya virginiana\ hackberry (Celtis occidentalis), flowering dogwood (Comus Jlorida) and, in the more southerly sites, bladdemut (Staphylea trifolia), are subcanopy trees that grow in the fairly open understory, with occasional prickly ash (Zanthoxylum americanum). The herbaceous layer tends to be rich in species, including four-leaved milkweed (Asclepias quadrifolia\ sickle-pod (Arabis canadensis), thread-leaved sedge (Carex ebumea\ broad-leaved ragwort (Senecio obovatus\ wild geranium (Geranium maculatum). In open (disturbed) areas, red cedar (Juniperus virginiana) and aspen (Populus tremuloides) may be common, often with non-native species. Although black maple (Acer nigrum) is associated with this community in the Midwest, it seldom occurs in this community in Massachusetts vdiere black maple tends to be associated with moister conditions.

Dense canopies with 80 to 100% closure, dominated by hemlocks. Little vmderstory grows in the shade of the hemlocks.
Moist, usually north facing, slopes, or along north facing ravines. Usually acidic rock. Occasional rock outcrops in the ravines.
Vegetation Description: A hemlock (Tsuga canadensis) dominated community. This commimity usually occurs within the oak -
hemlock - white pine communities. Occasional deciduous trees that grow with the hemlock, at very low percentages, include mixed oaks (scarlet, red, white, and black) (Quercus coccinea, rubra, alba, and velutina), and red maple (Acer rubrum). The shrub layer is sparse, with occasional individuals of the canopy species and small patches of mountain laurel (Kalmia latifolia). The herbaceous layer is essentially non-existent The forest floor is covered by needles, twigs, and small branches.

Habitat Values for Associated Fauna:
The Acadian Fly-catcher {Empidonax virescens) is a near obligate to Hemlock forests in Massachusetts, although its habitats are broader to the north. Other species that use the hemlock community tend to be northern or conifer prefexring forest ^)ecies, including such birds as Black- throated Green Warbler (Dendroica virens\ Blackbumian warbler (D.fusca), Louisiana Waterthrush (Seiurus motacilld), and Winter Wren {Troglodytes troglodytes). In the winter, mixed flocks are common with chickadees {Poecile atricapillus\ kinglets (Regulus spp.X and nuthatches (Sitta spp.) . Mammals include those that are widespread and typical of northern and coniferous forests: red squirrels (Tamiasciurus hudsonicus), red-backed voles (Clethrionomys gapperi\ smoky shrew (SorexfumeusX and wiiite-footed mouse (Peromyscus leucopus).

Habitat Values for Associated Fauna:
Closed canopy dominated by a mix of evergreen and deciduoxis trees, with sparse shrub and herbaceous layers.
Widespread in dry to mesic, moderately acidic conditions with moderate levels of nutrients. North facing slopes and ravines, and northern areas.
The community type ranges from Hemlock in pure stands to a deciduous forest with scattered hemlocks. There are variable combinations of hemlock (Tsuga canadensis), sugar maple (Acer saccharum), yellow birch (Betula alleghaniensis), black cherry {Primus serotina), and red oak (Quercus rubra), and white pine (Pinus strobus) There are often scattered paper birch (Betula papyri/era), aspen (Populus tremuloides\ red maple (Acer rubrum\ and yellow birch (Betula alleghaniensis). The shrub layer is usually open, but, often containing scattered clumps of hobblebush (Viburnum lantanoides), red-berried elderberry (Sambucus racemosa ssp. pubens\ fly-honeysuckle (Lonicera canadensis\ and striped maple (Acer pensylvanicum). The herbaceous layer is ^)arse, but fairiy diverse, with intermediate woodfem (Dryopteris intermedia), Christmas fern (Potystichum acrostichoides\ clubmosses (Lycopodium spp.X Canada mayflower (Kiaianthemum canadense\ white wood aster (Aster divaricatus\ and wild sarsap)arilla (Aralia nudicaulis). Occasional spring herbaceous species include painted trilhum (Trillium undulatum\ early yellow violet (Viola rotundifolia), broad-leaved spring beauty (Claytonia caroliniana), and trout-lily (Erythronium americanum).
Many animal species use parts of this type of forest, but geographical variation, structure, size, and local conditions will affect which actual species are present. Many species of neo-tropical migrant songbirds nest in large numbers in larger occurrences, including a variety of warblers. Blackbumian warblers (Dendroicafusca) are particularly closely associated with hemlock stands. Northern Goshawk (Accipiter gentilis). Barred Owl (Strix varia\ and Pileated Woodpeckers (Dryocopus pileatus) are also to be ejqjected. Mammals include red squirrels (Tamiasciurus hudsonicus\ gray squirrel (Sciurus carolinensis\ chipmunks (Tamias striatus\ redbacked vole (Clethrionomys gapperi\ short-tailed shrew (Blarina brevicaudd), masked and smoky shrews (Sorex cinereus and S./umeus\ and white-footed mouse (Peromyscus leucopus). At elevation, deer mouse (P. maniculatus) and woodland jumping mouse (Napaeozapus insignis) also occur in the forest type. Amphibians include redbacked salamanders (Plethodon cinereus) and wood frogs (Rana sylvatica); and expected reptiles include redbelly snakes (Storeria o. occipitomaculata).

Habitat Values for Associated Fauna:
A broadly defined time sequence of forest communities, from thick young sprouts with little diversity to mature, diversifying forests with undergrowth of more shade tolerant trees. The canopy is seldom completely closed and undergrowth may be dense or open.
Areas with past major disturbance such as cutting, hurricane, or fuie within northern hardwood forest areas.
Aspen (Populus tremuloides), white birch {Betula papyrifera\ red maple {Acer rubrum), and /or black cherry (Prunus serotina) dominate the community. Gray birch {Betida populifolia) tends to be more common on very well drained soils. Pin cherry {Prunus pensylvanica) is a common associate. As the forest matures, the understory is made \xp of young trees of more shade tolerant species. Shrubs and herbaceous species are variable, and depend on surrounding seed sources and the type of disturbance the established the early successional community.
The structure of a community is important to animals. Successional communities change in structure quite quickly, and the animals change as the vegetation grows, and there is a sequence of use. For 0 to 10 years trees are dense but small, often with blackberry {Rubus spp.) below. Fugitive bird species such as Chestnut-sided Warblers {Dendroica pensylvanica) and Mourning Warbler {Oporomis Philadelphia) are common in the fust 5 years after a major disturbance even, eqjecially if there are dead snags left for singing perches Grouse {Bonasa umbellus) and woodcock {Scolopax minor) are classic users of younger forest, as is the New England cottontail {Sylvilagus transidonalis). After 30 years, the community should include most commonly found mammals.

Vegetation Description:
Associations:
Habitat Values for Associated Fauna:
Forests with species of northern hardwoods (maples) and central hardwoods (oaks) together. Has few of the extreme northern or southern indicators.
Mesic forests of niid slopes, moderate nutrient availability, and not very acidic. Some sites, especially with abundant white pine, are old field successionaL, and others have been managed as woodlots and were selectively cut in the past, or may continue to be logged to the present The imderstory reflects the history of the sites.
Northern red oak (Quercus rubra), sugar maple (Acer saccharum), beech (Fagus grandi/oUa), and black birch (Betula lenta\ with an admixture of white pine (Pintis strobus) and hemlock (Tsuga canadensis) dominate the canopy in variable proportions White oak (Quercus alba\ red maple (Acer rubrum\ white ash (Fraxinus americana), and yellow birch (B. alleghaniensis) are regular associates. Striped maple (Acer pensylvanicum\ maple-leaved viburnum (Viburnum acerifolium\ and hobblebush (Viburnum lantanoides) are typical shrubs of primary transition forests, and lowbush blueberry (Vaccinium angustifolium\ is abundant in the more coniferous dominated sites. The herbaceous layer is neither dense nor sparse, often with patches of clonal species, includes wild sarsaparilla (Aralia nudicaulis\ bracken fern (Pteridium aquilinum), hay scentoi fern (Dennstaedtia punctilobula\ clubmosses (Lycopodium clavatum and L. obscurum), Indian cucumber (Medeola virginiana\ Canada mayflower (Maianthemum canadense), and whorled wood-aster (Aster acuminatus).
This wide^read forest type provides habitat to many, particularly to oppwrtunistic, animal species. White-tailed deer (Odocoileus virginianus) are classic users of this forest type, although certainly not limited to it Fisher (Martes pennanti) use larger, older examples. Many species move through the forest between other, specific habitats: frogs and salamanders breed in vernal pools and other wetlands and use the uplands in the rest of the year. Most of the widesj^'ead small mammals would be expected in larger occurrences of the community.

RICH, MESIC FOREST COMMUNITY
CT1C2A0000
S3
Yes
i^'^
Concept: A variant of the northern hardwood forest where sugar maple is usually dominant and there is a diverse
herbaceous layer with abundant spring ep^emerals in a moist, nutrient rich environment
Environmental Setting: Rich, mesic forests arc usually found on slopes or talus below calcareous bedrock or on level areas
where calcareous or circimineutral bedrock is near the surface [areas of enrichment can also occur where bedrock or till are not particularly base rich, but near the location where downslope enrichment takes place]. In Massachusetts, they are restricted to low to moderate elevations below 2,400 ft. (about 650 m), and usually on north or east-facing, concave, middle to lower slopes that exjjerience downslope movement of nutrients and organic matter. Rich refers to rich in nutrients, although they are also rich in species; and mesic is the moderate moisture regime. Soils are usually deep, with rapid decomposition of leaves and other plant litter quickly incorporated into the soil, so that there is rarely more than one year's accumulation of leaves on the forest floor.
Vegetation Description: Rich mesic forests are dominated by sugar maple (Acer saccharum), with white ash (Fraxinus
americana\ bittemut hickory (Carya cordiformis), elm species (Ulmus spp.X and basswood {Tilia americana) being other characteristic trees. Butternut (Juglans cinerea) usually grows in rich mesic forests but is infrequent Hophombeam (Ostrya americana) is common as a subcanopy tree Although the shrub layer is usually sparse, alternate-leaved dogwood (Comus altemifolia\ witch-hazel (Hamamelis virginiana), leatherwood (Dirca palustris), or red-berried elderberry (Sambucus racemosa ssp. pubens) might be present Typically spring ephemerals are abundant. Combinations of any several of the following ^lecies usually indicate a rich mesic commimity: bloodroot (Sanguineria canadensis^ maidenhair fern (Adiantum pedatum\ blue cohosh (Caulophyllum thalictroides\ sweet cicely (Osmorhiza claytonii), Dutchman's breeches (Dicentra cucullaria\ squirrel com {Dicentra canadensis\ toothwort (Dentaria diphylla\ wild leeks {Allium tricoccum), wild ginger (Asarum canadense), white banebeiry (Actea pachypoda), Goldie's fern (Dryopteris goldiana\ and zigzag goldenrod (Solidago flexicaulis) as well as the state-listed qsecies listed below. Two semi-evergreen, fairly distinct sedges (Carex plantaginea and C. platyphylla) are good indicators of the community that are visible throughout the year.

Concept:
Environmental Setting:
Hardwood forests on slopes, with small springs and seeps on mucky soils. Canopy is from or similar to, the surrounding forest, but shrub and herbaceous layers species are typical of wetlands or mesic areas.
Seeps may be near stream heeidwaters, or may be isolated with the water absorbed into the surroundings. They occur where the top of the ground water table intersects the surface, and the water emerges.
Vegetation Description: Canopy is usually northern hardwood species such as sugar maple (Acer saccharum), white ash
(Fraxinus americana), red maple {Acer rubrum\ yellow birch (Betula alleghaniensis\ and white birch (5. papyri/era). Other sites have hemlock (Tsuga canadensis) ^ruce (Picea rubens\ and scattered white pines (Finns strobus) among the hardwoods. Ferns are typical: cinnamon fern (Osmunda cinnamomea), ostrich fern (Matteuccia stnithiopteris), silvery spleenwort (Deparia acrostichoides\ rattlesnake fern (Botrychium virginianum), and Christmas fern (Polystichum acrostichoides). Golden saxifrage (Chrysoplenium americanum) primarily occurs in seeps. Scouring rush (Equisetum hyemale), false hellebore (Veratrum viride), water avens (Geitm rivaleX an assortment of sedges are among the other plants found at seeps.

Habitat Values for Associated Fauna:
Within hardwood forests on slopes, with small springs and seeps containing water with dissolved calcium emerge from the ground where the surface intersects the top of the water table. Canopy is of the surrounding forest although more open, but shrub and herbaceous layers species are typical of calcareous wetlands. Usually very small, much less than an acre in size. The community as defined is close to a Calcareous Sloping Fen.
Seeps may be near stream headwaters, or may be isolated with the spring water spilling out to be absorbed into the surroundings. Calcareoiis forested seeps receive water that has flowed through or been in contact with limestone or other calcareous rock or gravel. Sites in the Berkshire highlands and Vermont Piedmont tend to have fewer of the rarer calcareous fen species that are thought to be restricted to the richest sites.
Calcareous seeps typically occiir within rich northern hardwoods and share the tree canopy species of the surrounding forest such as sugar maple (Acer saccharum), white ash (Fraxinus americana\ beech {Fag}is grandifoUa), black birch {Betula lenta\ and red oak (Quercus rubra), although white pine (Pintts strobus) and hickories (Carya spp.) are also reported. The canopy is usually more open than in the surrounding forest Black ash, typical of wet calcareous communities, also occurs in calcareous forested seep communities. witch-hazel(//a/na»ie/j5 virginiana), ironwood {Carpinus caroliniana), alternate- leaved dogwood (Comus altemifolia\ striped maf\c {Acer pensylvanicum\ and young of the canopy species contribute to a scattered shrub layer. The herbaceous layer varies from sp)arse to continuous and includes many widespread wetland species such as sensitive fern (Onoclea sensibilis), yellow jewel weed (Impatiens pallida), aivi jack-in-the-pulpit (Arisaema triphyllum\ Key indicator calcareous species include many calcareous fen indicators as well: shrubby cinquefoil {PentaphylloidesJloribunda\ alder- leaf buckthorn {Rhamnus alnifolia), wild black currant (Ribes americanum\ yellow sedge (Carexjlava\ porcupine sedge (Carex hystericina\ hoary willow {Salix cai\dida\ autumn willow {S. serissima\ purple avens (Geum rivale), rough-leaved goldenrod (Solidago patula\ and grass-of-pamassus {Pamassia glauca).
As with other seeps, these small communities provide parts of the habitats of the species of surrounding communities. Most tree dwelling qjecies would not be affected by the presence of small seeps below. Star-nosed moles {Condylura cristata) would be expected in seeps of any kind. If the water from the seeps stays in topographic low areas those may function as vernal jxxjls, and support vernal pool breeding species.

Habitat Values for Associated Fauna:
A northern and higher elevation mixed red spruce - northern hardwood forest
Tends to be in cool, and typically rocky soils, nutrient poor, somewhat dry, and acidic. Grades into northern hardwoods - hemlock - white pine forests on moister, warmer slopes.
A community of variable dominance: red spruce may be dominant, or co-dominant with sugar maple and beech (or these may be dominantX vvith abundant yellow birch and smaller amounts of red spruce and/ or balsam fu". Hemlock (Tsuga canadensis) can be abundant or scattered. Heart-leaf paper birch (Betula cordifolia) and paper birch (Betula papyri/era) usually occur as scattered individiials. Characteristic shrubs include mountain maple (Acer spicatum), red-berried elder (Sambucus racemosa var. pubens), northern mountain ash (Sorbus americana\ and hobblebush (Viburnum lantanoides). A low shrub layer has bunchbeny (Comus canadensis), creeping snowbeny (Gaultheria hispidula), and occasionally, twinflower (Linnea borealis). The herbaceous layer tends to be sparse, e^jecially when spruce is abundant; plants include intermediate fern (Dryopteris intermedia), mountain wood fern (Dryopteris campyloptera\ blue-bead lily (Clintonia borealis), painted trillium (Trillium undulatum\ and wood sorrel (Oxalis acetosella).
Animals of this community tend to be northern species that are more typical of forests of Vermont and New Hampshire. Birds include Golden-crowned Kinglet (Regulus satrapa\ Blue-headed Vmeo (Vireo solitarius), and species of big warblers including Blackbumian (Dendroica Jusca\ Yellow- rumped (D. dominica), and Magnolia Warbler (D. Magnolia). Mammals include fisher (Martes pennanti), as a classic example, and northern species such as red squirrels (Tamiasciurus hudsonicus\ snowshoe hare ( Lepus americanus), in the open areas, northern flying squirrels (Glaucomys sabrinus\ and Pygmy shrews (Sorex hoyi). Amphibians would include the ubiquitous redbacked salamanders (Plethodon cinereus), wood frogs (Rana sylvatica\ and red efts, the juvenile stage of red-spotted newt (Notophthalmus v. viridescens).

©MAIFT Descriptions of
Palustrine Communities
BMAFT
Classification of the
Natural Communities
of
Massachusetts
The palustrine section of the Massachusetts* natural community classification includes all freshwater, non-tidal wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens. This definition is slightly different from Cowardin (1979) who also included small, sJiallow aquatic beds with submersed and floating-leaved aquatics, and tidal wetlands where salinity due to ocean-derived salts was less than 0.5%. In the Massachusetts' classiiication, submersed and floating leaved aquatics are included in the lacustrine section, and all tidal wetiands are included in the estuarine section. The palustrine section does include riverside communities that receive annual or semi-annual overbank flooding, e.g. floodplain forests. High-terrace floodplain forests (although technically terrestrial communities) are included in the palustrine section in order to group them with other floodplain forest communities.
The organization of the palustrine classification is given in the palustrine table of contents, which follows. A primary division is made between forested (>50% tree canopy cover) and non-forested wetiands. Within the forested section, a second division is made between conifer-dominated (conifers providing >50% of the total canopy coverage) and hardwood-dominated communities. The forested/non-forested and conifer-Zhardwood- dominated divisions are intended to aid the user in identifying community types. It should be recognized, however, that there are continuous gradients in communities from forested to non-forested and from conifer- to hardwood- dominated. The boundaries between these types and between the named communities are not absolute. Communities intergrade and several may occur together within a weUand mosaic.
The organization described above differs from that of the original classification used by Nfassachusetts (Rawinski 1984) which made a primary division between basin and seepage wetiands. For most of Massachusetts' wetiand communities, detailed environmental data (particularly hydrologic data) are lacking making distinctions between basin and seepage wetiands uncertain. Until there are sufBcient data to support differences between seepage and basin types, the types are lumped into one name that describes the overall vegetation of the community. For example, the previously used names Southern New England Basin Swamp and Southern New England Seepage Swamp are replaced by Red Maple Swamp for those swamps in which red maple is dominant. Rich and poor variants are described within the vegetation description. However, the names "calcareous seepage swamp" and "calcareous seepage marsh" are retained due to their common usage.

Forested wetlands of western and north-central Massachusetts dominated by red ^ruce eind balsam fir.
Spruce-fir swamps are typically found at stream headwaters or in poorly drained basins in the moimtainous, northwestern part of the state. They develop in cold, poorly drained areas, typically on eicidic glacial till. Elevation ranges from 1 500-2000 ft. in the Berkshire Highland s [Weatherbee 1 996]. Peat accumulation appears to be minimal at most known sites. More work is needed to describe the physical setting and soil profiles of boreal swamps.
Red spruce (Picea rubens) and balsam fir (Abies balsamed) are dominant in the overstory. Other canopy associates are white pine (Pintis strobusX black cherry (Prunus serotina\ tamarack (Larix laricina), black spruce (Picea mariana), paper birch (Betula papyri/era), hemlock (Tsuga canadensis), yellow birch (Betula alleghaniensis), and red maple (Acer rubrum). Unlike spruce-tamarack forested bogs, spruce-fu" boreal swamps have red spruce rather than black spruce co-dominant in the canopy, and they typically leick bog indicator ^)ecies like Labrador tea (Ledum groenlandicum) and bog laurel (Kalmia polifolia). The following three shrubs almost always occur in boreal swamps: mountain holly (Nemopanthus mucronatus\ sheep laurel (Kalmia angustifolia\ and wild raisin (Viburnum nudum var. cassinoides). Other shrubs include American mountain-ash (Sorbus americana), hobble-bush (Viburnum lantanoides), and mountain maple (Acer spicatum). Typical herbaceous species are northern awned sedge (Carex gynandra\ New England sedge (Carex novae-angliae\ goldthread (Coptis trifolia ssp. groenlandica\ creeping snowberry (Gaultheria hispidula), blu^)ead-lily (Clintonia borealis\ one- sided pyrola (Orthilia secunda\ bishop's cap (Kiitella diphylla\ lesser mitrewort (Mitella nuda\ mountain wood-sorrel (Oxalis montana\ royal fern (Osmunda regalis\ and pale St. John's-wort (Hypericum ellipticum). The ground is often a carpet of mosses; more information is needed on the characteristic moss species. Richer variants of the community can occur in areas of calcareous groundwater seepage, but more information is needed.
No associations have been described in Massachus^ts.
Spruce-fir boreal swamps can function as vernal pool habitat if water remains standing
for 2-3 months and they lack fish; these areas provide important amphibian l^-eeding habitat

Acidic forested swamps where hemlock is dominant or co-dominant in the canopy.
Hemlock-hardwood swamps occur in poorly drained basins in bedrock and till throughout the central and western portions of the state. The soil is muck and it is saturated throughout the year. Some groundwater seepage appears to be typical. At sites where mixed hemlock swamp and red maple swamp occur [1000 Acre Swamp in Athol and Phillipston], hemlock-dominated areas appear to occupy higher elevations. More information is needed to characterize the envirorunental setting and physical characteristics of hemlock-hardwood swamp forests.
Many swamps have hemlock (Tsuga canadensis) as a component of the canopy but "hemlock-hardwood swamps" are differentiated from others by having hemlock as the major canopy species. In some cases, hemlock forms dense stand s. In other cases, probably more commonly, hemlock is associated with a mixture of white pine {Pinus strobus), red maple (Acer rubrum\ and yellow birch (Betula alleghaniensis). The hemlock-dominated canopy allows little light into the subcanopy and shrub species are ^larse, but shrubs can form dense thickets in canopy gaps. Typical shrubs include alders (Alnus spp.), highbush blueberry (Vacdnium corymbosum), winterberry {Ilex verticillata\ and mountain holly {Nemopanthus mucronatus). The ground layer is hummocky and covered in various moss sjjecies. Ferns are common, especially cinnamon fern {Osmunda cinnamomea). Sensitive fern (Onoclea sensibilis) also occurs. Goldthread {Coptis trifolia ssp. groenlandic)a is characteristic. In areas where hemlock is mixed with hardwoods, there appjears to be higher q)ecies diversity. Woodfems— including spinulose woodfem {Dryopteris carthusiand), intermediate woodfem {D. intermedia), and crested woodfem (D. cristata)— can be abundant in the herbaceous layer. Rich variants of hemlock-hardwood swamps occur. One rich site located at the base of a steq) forested slope in Huntington has a mixture of spice bush (Lindera benzoin), mountain-laurel (Kalmia latifolia), and hobble-bush {Viburnum lantanoides) in the shrub layer, and an herbaceous layer of more than 20 ^)ecies, including jack-in-the-pulpit {Arisaema triphyllum), spotted touch-me-not {Impatiens capensisX Pennsylvania bittercress {Cardamine pensylvanica), cinnamon fem {Osmunda cinnamomea\ interrupted fem {Osmunda claytoniana\ goldthread {Coptis trifolia ssp. groenlandica), and blue marsh- violet {Viola cucullata). Rich hemlock- hardwood swamps are differentiated from calcareous seqiage swamps by their lower herbaceous species richness, about 20 species as compared to >40 for calcareous seepage swamps, and their lack of characteristic calciphiles, such as deUcate sedge {Carex leptalea), brome-like sedge {Carex bromoides\ long-stalked sedge {Carex pedunculata), rough-leaved goldenrod {Solidago patula\ and golden ragwort {Senecio aureus).
No associations have been described in Massachusetts.

Habitat values for Associated Fauna:
Basin swamps dominated by Atlantic white cedar (AWC) in the overstory and a mixture of coastal species in the understory.
Coastal AWC swamps typically occur at low elevations, less than 40 ft. above sea level, in basins overlying sand and gravel deposits or glacial lake bottom sediments. They are limited to coastal regions of the state. Water-saturated peat overlies the mineral sediments, and standing water generally occurs for half of the growing season or longer. The water and soil are nutrient-poor, and particularly low in nitrogen and phosphorus. There is a high iron content in the soil; the iron, called "bog iron," was mined in the early days of manufacturing. Soil pH is acidic, 3.1-5.5, and leaf litter decomposition is slow.
Atlantic white-cedar (Chamaecyparis thyoides) is the dominant tree mixed with red maple {Acer rubrum). Pitch pine {Pinus rigida), white pine (Pinus strobus\ and hemlock (Tsuga canadensis) are infrequent associates. These swamps can have a very dense shnib layer, including high-bush blueberry (Vaccimum corymbosum), swamp azalea {Rhododendron viscosum), sweet pepperbush {Clethra alnifolia) and fetterbush {Leucothoe racemosa). In Cape Cod sites, inkberry {Ilex glabra) frequently occurs. The herb layer is sparse and paXchy with cinnamon fern {Osmunda cinnamomea), Virginia chain fern {iVoodwardia virginioaX starflower {Trientalis borealis) and wild sarsaparilla {Aralia nudicaulis). The ground layer is dominated by Sphagnum spp. mosses.
Motzkin (1991) described six AWC associations in Massachusetts. Coastal AWC swamps are equivalent to his Coastal AWC Type.
Yoimg AWC thickets provide excellent cover for deer, rabbits and birds. Atlantic white-cedar foliage and twigs are preferred winter browse for white-tailed deer, while rabbits and mice can feed on cedar seedlings. Although no bird species appear to be restricted to AWC communities, studies have shown these wetlands to be important bird habitat. Birds that have been observed nesting in AWC swamps include Red-breasted Nuthatch, Brown Creeper, Black-and -white Warbler and Black-capped Chickadee. Coastal AWC swamps can ftinction as vernal pool habitat if water remains standing for 2-3 months and they lack fish; these areas provide important amphibian breeding habitat

Marconi AWC Swamp, Cape Cod National Sea Shore, WellfleeL
The two greatest threats to AWC swamps are land clearing for agricultural, commercial and residential development, and interference of normal hydrological functioning as a result of development. Atlantic white-cedar has been cut extensively for posts and shingles for over three centuries. In an extensive statewide vegetation inventory funded by MNHESP in 1990, no uncut stand s were found, but several sites contained cedars that were 100-200 years old. Selective cutting is detrimental to the persistence of AWC swamps, because hardwoods, such as red maple, out-compete and replace AWC. Any alterations to the natural hydroperiod of AWC swamps threatens their persistence.
Due to the limited distribution of AWC swamps, it is recommended that no clearing or filling of these wetlands be allowed. Atiantic white-cedar will regenerate best following catastrophic disturbance events such as hurricanes and fires. Data suggest that in the absence of disturbance, red maple and shrubs increase in abundance at the expense of AUantic White-Cedar. Fire suppression negatively threatens the long-term persistence of AWC swamps, and controlled burning fjtactices may be an appropriate restoration tool in many areas. Controlled burning should be accompanied by small-patch clearcuts to be most effective. By clear-cutting small patches, generally 20 m x 20 m, &nd removing the slash and competing vegetation, pure, even-aged stand s of Atiantic White-Cedar are able to regenerate. AWC swamps require a natural cycle of wet and dry periods for their survival and reproduction. Standing water for much of the year is unfavorable for both seed germination and seedling survival, and young seedlings are killed by both drowning and drought It is recommended that any alterations in water levels be avoided, this includes development and road construction in uplands surrounding AWC swamps which can alter water levels. Where cedar weUands are associated with river systems, it is important to maintain normal hydrologic regime of the river.

INLAND ATLANTIC WHITE CEDAR SWAMP
CP1B1A2000 S2 Yes
Concept: Inland basin or seepage swamps dominated by Atlantic white cedar in the overstory. Hemlock, spruce,
red maple, and yellow birch co-occur, and coastal indicator species are lacking.
Environmental setting: Basin or seepage wetlands generally occurring in the central part of the state. Inland AWC swamps are
found at a wide range of elevations and may be underlain by sand and gravel, glacial lake sediments, or till deposits. There is typically some surface water movement, and some of the sites receive groundwater seepage from nearby steep till deposits. As in all AWC swamps, water-saturated pjeat overUes the mineral sediments, and standing water generally occurs for half of the growing season or longer. The water and soil are nutrient-poor, and particularly low in nitrogen and phosphorus. Soil pH is acidic (3.1- 5.5) and leaf litter decomposition is slow.
Vegetation Description: Canopy trees in Inland AWC swamps differ depending on elevation. In sites lower than 700 ft.
elevation, Atlantic White-Cedar (Chamaecyparis thyoides) is mixed with hemlock (Tsuga canadensis), red maple {Acer rubrum\ and yellow birch {Betula alleghaniensis). At elevations above 700 ft., Atlantic white-cedar is mixed with hemlock and spruce (Picea spp.). The low elevation sites typically have sweet pepperbush {Clethra alnifolia) and winterberry {Ilex verticillata) in the shrub layer, and high elevation sites have atnmdant mountain holly (Nemopanthus mucronata). The herb layer of both low- and higher- elevation sites is similar with cinnamon fern, starflower and Canada mayflower {Maianthemum canadense) common. High-elevation sites also have northern species such as creeping snowberry {Gaultheria hispidula) and bunchberry {Comus canadensis).

A variant of spruce-fir boreal swamps in which Atlantic white cedar is an associate in the tree canopy.
Northern AWC swamps are restricted to basins at high elevations; the one described occurrence in Massachusetts occurs at an elevation of 1 ,1 10 feet and is currently the highest known elevation for Atlantic White-Cedar in the state. As with all AWC swamps, water-saturated peat overUes the mineral sediments, and standing water generally occurs for half of the growing season or longer. The water and soil are nutrient-poor, aiKl particularly low in nitrogen and phosphorus. There is a high iron content in the soil; the iron, called "bog iron," was mined in the early days of manufacturing. Soil pH is acidic (3.1- 5.S) and leaf litter decomposition is slow.
Northern conifers, such as black and red spruce (Picea mariana and P. rubens\ and balsam fir {Abies balsamea) dominate the overstory, and Atlantic White-Cedar (Chamaecyparis thyoides) occurs as an associate. Shrubs and herbs are similar to those found in high-elevation Inland AWC swamps, especially mountain holly (Nemopanthus mucronatus\ creeping snowberry (Gaultheria procumbens), and bunchberry (Comus canadensis). Labrador tea (Ledum groenlandicum) and rhodora (Rhododendron canadense) are also common.

ALLUVIAL ATLANTIC WHITE CEDAR SWAMP
CP1B1A4000 S2 Yes
Forested swamps occurring along low-gradient rivers \viiere Atlantic white cedar is co-dominant with red maple in the overstory.
Alluvial AWC swamps differ from other AWC wetlands in that they occur witliin the floodplain of rivers and streams or at the fringes of open marshy areas along ponds. They receive annual or semi- annual overbank flooding making them more mineral-rich than other AWC wetland s. As with all AWC swamps, water-saturated peat, generally about 1 m thick in alluvial examples, overlies the mineral sediments, and standing water generally occurs for half of the growing season or longer.
Alluvial AWC swamps are highly variable in their composition. Atlantic white-cedar {Chamaecyparis thyoides) and red maple {Acer rubrwn) domixmte the tree layer, and high-bush blueberry {Vaccinium corymbosum) and sweet pepperbush (Clethra alnifolia) occur in the shrub layer along with silky dogwood {Comus amomum). The herb layer is comprised of species common to very wet, open or enriched sites, including sensitive fern {Onoclea sensibilisX royal fern {Osmunda regalis), bugleweed (Lycopus spp.X marsh fern {Thelypteris palustris\ and marsh SL John's-wort {Hypericum virginicum).

Acidic forested peatlands with an overstory of black spruce and tamarack and an understory of heath shrubs on sphagnum moss.
Forested bogs occur in a variety of physical settings, primarily in the north-central and western parts of the state. They occur in kettlehole depressions, watershed divides, and along pond margins. Forested bogs are late-successional peatlands that typically occur on thick peat deposits.
Black spruce (Picea mariana) and tamarack (Larix laricina) are dominant in the overstory. Red spruce (Picea rubens) can occur in place of black spruce. The trunks and branches are often covered and draped in lichens, especially Usnea spp. Other trees that occur in lesser amounts are white pine (Pinus strobus), pitch pine {Pinus rigida), and red mq)le {Acer rubrum), but red spnice (Picea rubens) can also occur. A mixture of tall shrubs and short, ericaceous shrubs provide nearly continuous cover in the imderstory. Labrador tea {Ledum groenlandicum) and bog-laurel {Kalmia polifolia) are good indicators of the community, but they do not always occur. Other common shrubs are mountain-holly {Nemopanthus mucronatus\ wild raisin {Viburnum nudum var. cassinoides\ and sheep-laurel {Kalmia angustifolia). The ground is covered in Sphagnum spp. moss with three-seeded bog salge {Carex trispemta), three-leaved Solomon's seal {Maianthemum trifolium\ bluebead-lily {Clintonia borealis\ goldthread {Coptis trifolia ssp. groenlandica), and creeping snowberry {Gaultheria hispidula).

RED MAPLE SWAMP
CP1A2A1000 S5 No
Concept: Acidic forested swamps with red maple dominant in the overstory. Red maple swamps are the most
common forested wetlands in Massachus^ts.
Environmental setting: Red maple swamps occxir in a variety of physical settings. Golet at al. (1 993) describe three basic
types: hillside seeps and upland drainageways fed primarily by groundwater seepage and overland flow, seasonally flooded basin swamps in undrained basins; and alluvial swamps. The last category is classified separately in Massachusetts as Alluvial Swamp Forest. Depending on the physical setting, red maple swamps receive water through surface runoff, groundwater inputs, or stream and lake overflow. The hydrogeologic setting is the primary determinant of water regime and the plant community structure and composition. pH ranges from less than 4 to 7. Soils have shallow to thick organic layers overlying mineral sand s/silts.
Vegetation Description: Red maple is usually strongly dominant in the overstory, and often provides more than 90% of the canopy cover. A variable mixture of tree species co-occurs with red maple, including yellow birch {Betula alleghaniensis), black gum (Nyssa sylvatica\ white ash (Frndnus americana\ white pine (Pinus strobus), American elm (Ulmus americana), and hemlock (Tsuga canadensis). Pin oak (Quercus palustris), and swamp \v1ute oak (Quercus bicolor). Atlantic white cedar {Chamaecyparis thyoides) is a common associate in coastal areas and locally at sites in central Massachusetts and the lower Connecticut Valley. When Atlantic white cedar is dominant in the overstory, the community is classified as an Atlantic wliite cedar swamp. The shrub layer of red maple swamps is often dense and well-developed, generally with >50% cover but it can be variable. In eastern Massachusetts, sweet pepperbush (Clethra alnifolia) and swamp azalea {Rhododendron viscosum) are the dominant shrubs. Other common shrubs are highbush blueberry (Vacdnium corymbosum) and common winterberry (//ex verticillata\ which are often dominant, and spicebush (Lindera benzoin); usually in richer areas, northern arrow-wood ( Viburnum dentatum var. lucidum), ^jeckled alder (Alnus incana ssp. rugosa\ nannyberry {Viburnum lentago\ and poison sumac {Toxicodendron vemix). The herbaceous layer is highly variable, but ferns are usually abundant Cinnamon fern {Osmunda cinnamomea) is common; other ferns include sensitive fern {Onoclea sensibilis), royal fern {Osmunda regalis\ marsh fern {Thelypteris palustris), and spinulose wood fern {Dryopteris carthusiana). Graminoids are common, mixed with a variety of herbaceous species. Some of the most common herbaceous species are skunk cabbage {Symplocarpus foetidus\ false hellebore {Veratrum viride\ spotted touch-me-not {Impatiens capensis\ swamp dewberry {Rubus hispidus\ marsh marigold {Caltha palustris), and the bugleweeds {Lycopus spp.). Rich variants of red maple swamps occur, apparently associated with groundwater seepage. Two rich variants are tracked separately: 1 . "Calcareous seepage swamps" are black ash-tamarack-red maple associations with abundant calciphihc herbaceous species occurring on calcareous bedrock in western Massachusetts, and 2. "Black ash swamps" have black ash co-dominant in the canopy, a high diversity of herbaceous species, and appear to occur in areas with circumneutral seepage. There are also rich variants of red maple swamps that lack the black ash of "black ash seepage swamps" and the calciphiles of "calcareous seepage swamps." More information is needed on rich red maple swamps; they may warrant separate tracking.
Associations: No associations have been described in Massachusetts.
Habitat values for Associated Fauna:
Red maple swamps can function as vernal pool habitat in sections that have two or three months of ponding and lack fish; these sections provide important amphibian h-eeding habitat.

ALLUVIAL RED MAPLE SWAMP
CPiA2AlA00 S3 Yes
Concept A richer variant of red maple swamp that occurs in low areas along rivers and streams that experience
overbank flooding.
Environmental setting: Alluvial red maple swamp forests occur along mainstem sections of smaller rivers in eastern
Massachusetts (Nashua Assabet, Shawsheen, Concord, and Three Mile). They experience overbank flooding, but they appear to be more pooriy drained than true floodplain forests. Soils are typically silt loams with pronounced soil mottling and a surface organic layer.
Vegetation Description: The overstory of alluvial red maple swamps is characterized by a mixture of red maple (A. rubrum) and
silver maple (Acer saccharinum; particularly along riverbanks) with lesser amounts of green ash (Fraxinus pennsytvanica) and /or swamp white oak (Quercus bicolor). Red oak (Q. rubra), white pine (Pinus strobus), and black cherry (Prunus serotina) occur in elevated sections. Unlike true floodplain forests, alluvial swamp forests have well-developed shrub layers composed of northern arrow-wood (Viburnum dentatum var. lucidum), silky dogwood (Comus amomum\ and the non-native plant European buckthorn (Rhamnus frangula). The herbaceous layer is often dominated by sensitive fern (Onoclea sensibilis) and false nettle (Boehmeria cylindrica) mixed with a rich assemblage of herbaceous species tliat commonly includes royal fern (Osmunda regalis\ awned sedge (Carex crinita\ and bugleweeds (Lycopus sr).).

BLACK ASH SWAMP
CP1A2A2000 S2 Yes
Concept:
A variant of red maple swamps in which black ash (Fraxinus nigra) is co-dominant in the canopy. Black ash swamps are associated with circumneutral groundwater seepage.
Environmental setting:
Black ash swamps typically occur in areas with circumneutral groundwater seepiage. They can occur at the edge of river floodplains adjacent to the upland slope where seepage input occurs, as small seepy pockets within a larger matrix of red maple swamp, or at the headwaters of streams, which may be the typical location in northern and western parts of the state. The pH of black ash swamps in Essex Co. ranges between 7.0 and 7.4 [MacE>ougall, pers. comm.]. More information is needed on the physical characteristics of black ash seepage swamps.
Vegetation Description:
Black ash (Fraxinus nigra) is co-dominant with red maple (Acer rubrum) in the overstory. There are lesser amounts of sugar maple (Acer saccharum\ Eastern hemlock (Tsuga canadensis\ yellow birch (Betula alleghaniensis\ and white pine (Finns strobus). Ironwood (Carpinus caroliniana) is common in the sub-canopy, but it does not always occur. Common shrubs are spicebush (LinJera benzoin\ winterberry (Ilex verticillata), highbush bluebeny (Vaccinium corymbosum), mountain holly (Nemopanthus mucronata), northern arrow-wood (Viburnum dentatum var. lucidum), and occ£isional witch hazel (Hamamelis virginiana). Skunk cabbage (Symplocarpus foetidus) and cinnamon fern (Osmunda cinnamomea) are common heib species. Other herbaceous associates include sensitive fern (Onoclea sensibilis\ royal fem (Osmunda regalis), lady fern (/4f/j>num_/7/ir-_/^ffH>uiX jack-in-the-pulpit (Arisaema triphyllum), tussock sedge (Carex stricta), swamp-saxifrage (Saxifraga pensylvanica), and jewelweed (Impatiens capensis). The micro-topxjgraphy is hummock and hollow with abundant Sphagnum spp. moss, particularly on the hiunmocks. Black ash swamps occurring in Berkshire Co. or the Connecticut Valley that have species-rich herbaceous layers, with more than 40 species, and calcareous indicator species including dehcate sedge (Carex leptalea), lx"ome-like sedge (Carex bromoides\ long-stalked sedge (Carex pedunculata), rough-leaved goldenrod (Solidago patula), and golden ragwort (Senecio aureus) are classified separately as "black ash-red maple-tamarack calcareous seepage swamps."

Habitat values for Associated Fauna:
Mixed deciduous-coniferoxis forested swamps occurring in areas where there is calcareous groundwater seepage. The qjecies-rich herbaceous layer is characterized by calcium-loving species. Calcareous seepage swamps can also be called forested fens.
The occurrence of calcareous or circumneutral groundwater seepage defmes this community. The more calcareous the seepage, the more rare plant species are likely to be found. Soils are mineral but with a thin layer of peat accumulation at the surface. More information is needed on the physical characteristics of this community.
A variable mixture of deciduous and coniferous trees forms the canopy, but black ash (Fraxinus nigra\ tamarack (Larix laricina\ and red maple {Acer rubrum) are most common. Other associeited tree species at low elevations, less than 1 ,000 ft., are bur oak (Quercus macrocarpa), yellow oak (Q. muehlenbergii), yellow birch (Betula alleghaniensis), American elm (Ulmus americana), white pine (Pinus strobus), and hemlock (Tsuga canadensis). At higher elevations, red spruce {Picea rubens), balsam fir (Abies balsamea\ and Canada yew {Taxus canadensis) can also occur. Ironwood (Carpinus caroliniana) is characteristic of the subcanopy. The shrub layer can be dense, aixl characteristic ^)ecies are poison sumac {Toxicodendron vemix) and alder-leaf buckthorn {Rhamnus abiifolia), mixed with speckled alder {Alnus rugosa\ gray dogwood {Comus racemosa), winterberry (Ilex verticillata\ spicebush (Lindera benzoin\ meadowsweet (Spiraea latifolia), and highbush blueberry (Vaccinium corymbosum). Shrubby cinquefoil (Pentaphylloides Jloribunda) often occurs in open areas. The herbaceous layer is diverse with many calciphilic (calcium-loving) species mixed in with other common wetland plants Characteristic calciphiles are delicate sedge (Carex leptalea\ brome-like sedge (Carex bromoides\ long-stalked sedge (Carex pedunculata\ rough-leaved goldenrod (Solidago patula), and golden ragwort (Senecio aureus). Other typical species in the herbaceous layer are skunk cabbage (Symplocarpus foetidus\ sensitive fern (Onoclea sensibilis\ royal fern (Osmunda regalis), jewelweed (Impatiens capensis\ and naked mitrewort (Mitella nuda).

Vegetation Description:
Associations:
Habitat values for Associated Fauna:
A red maple-dominated basin swamp in which black gum, pin oak, and swamp white oak are important components of the overstory. This vegetation association is limited to lakebed sediments of glacial Lake Hitchcock in the Connecticut Valley.
These swamp forests generally occur in basins that have little or no slope where deposits of lake- bottom clays are overlain by silt and sand. The lake-bottom clays appear to be impermeable which creates a "perched" water table isolated from groundwater. There may be some connection to the groundwater along the margins of these wetlands or, to a more limited degree, through slow vertical movement. Periodic flooding occurs as indicated by the lack of organic matter accumulation. More information is needed to determine if this association is restricted to areas of perched water tables.
Red maple (Acer nibrum) dominates the overstory, but the southern tree species— black giun (Nyssa syh>atica\ pin oak (Quercus palustris\ and swan^ white oak {Quercus bicolor)— are co^ominanL Eastern hemlock (Tsuga canadensis) is a common associate. There is pronounced hunmiock-hollow topography, and most plants, except the sedges, are confmed to the hummocks. The shrub layer is similar to other swamp forests. Common species include highbush blueberry (Vaccinium corymbosum\ northern arrow-wood {Viburnum dentatum var. lucidum\ common winterbeny (Ilex verticillata) and serviceberry (Amelanchier spp.). The herbaceous layer is variable, but cinnamon fern (Osmunda cinnamomea) occurs at all known sites. Other common herbaceous species are Canada mayflower (Kiaianthemum canadense var. canadense), goldthread (Coptis trifolia ssp. groenlandica\ Indian cucumber-root (Medeola virginiana), and various sedge species (Carex spp.).
No associations have been described in Massachusetts.
Perched swamps can function as vernal pools in sections that have extended periods of ponding, 2-3 months, and lack fish; these sections provide important amphibian Ineeding habitat.

It is likely that this community type once covered a larger area of the Connecticut Valley, but much of the lake bottom has been cleared and converted to agriculture. Only patches of these perched swamps remain. Current threats include alteration of water chemistry from road and farm runoff, in particular, the accumulation of road salts, ditching by land owners to drain water, and logging.
Disturbed areas appear to have large amounts of European buckthorn {Rhamnus frangula). Efforts to prevent further disturbance may prevent the spread of this invasive plant species.

Forested acidic basin swamps with accumulations of peeiL Black gum is the dominant canopy tree.
Black gum swamps are forested hummocky peatlands that occur in poorly-drained basins. There can be small areas of seepage, usually at the edges of the basin, where seepage indicator plants such as black ash and bugleweed, occur. pH is strongly acidic and ranges from 3-5. More information is needed.
Black gum swamps have pronounced hummock-hollow topography, and woody vegetation is confined to the hummocks. The canopy is open, often in the 25-50% cover range. Black gum (Nyssa sylvatica) dominates the canopy, but red maple {Acer rubrum) and Eastern hemlock (Tsuga canadensis) are also abundant. Yellow birch (Betula alleghaniensis), white pine (Pinus strobus), red spruce (Picea rubens\ and black ash {Fraxinus nigra) may also be common. The shrub layer is well-developed; typical species include common winterberry {Ilex verticillata\ smooth winterberry {Ilex laevigata), mountain-laurel {Kalmia latifolia), common mountain-holly {Nemopanthus mucronatus), highbush blueberry {Vaccinium corymbosum\ and wild raisin {Viburnum nudum var. cassinoides). Herbaceous species occur on the hummocks and include cinnamon fern {Osmunda cinnamomea\ beggar-ticks {Bidens jrondosa\ goldthread {Coptis trifolia ssp. groenlandica), northern water-horehound {Lycopus unijlorus), swamp- dewberry {Rubus hispidusX marsh SL John's-wort {Triadenum virginicum), and Massachusetts fern {Thelypteris simulata). Wet hollows are typically lined with sedges including silvery bog-sedge {Carex canescens ssp. arctiformis), bladxler-sedge {Carex intumescens\ tussock-sedge {Carex stricta), and three-seeded bog sedge {Carex trisperma).

Habitat values for Associated Fauna:
Silver maple-dominated forest community of alluvial floodplains of the Connecticut, Deerfield and Housatonic Rivers.
Major-river floodplain forests are known to occur along mainstem sections of large rivers, such as the Connecticut, Housatonic, and Deerfield Rivers in Massachusetts. Soils are predominantly sand y loams without soil mottles and without a surface organic layer. Flooding at these sites occurs annually and is usually severe. An island variant of major-river floodplain forests [Type I in Kearsley, 1998] occurs on elevated sections of riverine island s and riverbanks of major rivers where there are high levels of both natural and human disturbance.
Major-river floodplain forests have silver maple {Acer saccharinum) strongly dominant in the overstory, with over 60% cover, mixed with lesser amounts of cottonwood {Populus deltoides). American elm (JUlmus americana) and /or slippery elm {U. rubra) occur in the subcanopy. Shrubs are generally lacking. The herbaceous layer is usually dominated by a 3-6 ft. [1-2 m] tall, dense cover of wood-nettles (Laportea canadensis). Ostrich fern {Kiatteuccia struthiopteris) is sometimes abundant Whitegrass (Leersia virginica) is consistently represented, but in low amounts, typically <5% cover. Other common associates are woodreed (Cinna arundinacea) and jack-in-the-pulpit (Arisaema triphyllum). An island variant of major-river floodplain forests [Type I in Kearsley, 1998] has similar species, but silver maple is not dominant in the overstory and the herbaceous layer is typically strongly dominated by ostrich fern. The overstory is an even mix of silver maple, cottonwood, sycamore {Platanus occidentalis\ and American ash {Fraxinus americana\ with box elder {Acer negundo) and hackberry {Celtis occidentalis; on the Housatonic River) common in the subcanopy. Species typical of disturbed areas, such as staghom sumac {Rhus typhina) and bittersweet {Celastrus orbiculata), are also common in this variant, as are the vines, riverbank grape {Vitis riparia) and Virginia creeper {Parthenocissus quinquefolia).
Two associations were described in Kearsley (1998). They are: Type I- Riverine island floodplain forests {Acer saccharinum-Populus deltoides-Acer negundo^atteuccia struthiopteris Association^ and Type II-Major-river floodplain forests {A saccharinum-P. deltoides-Laportea canadensis Association).
Floodplain forests are insect-rich habitats that attract warblers, thrushes and other songbirds. In particular yellow-throated and warbling vireos, which like to nest in the canopies of riverside trees, are frequently observed in floodplain forest communities. Raptors such as bald eagles and red-shouldered hawics also use riverbank trees as perch sites. In spring floods, wood ducks and hooded mergansers like the shady edges of floodplain forests and the interior meander scar pools. Eastern comma butterflies feed on elm and nettles, and the shady riverbanks are patrolled by several dragonfly species such as beaked and fawn darners. Interior meander scars and sloughs fimction as vernal pools providing breeding habitat for many frog species, such as leojsard and pickerel frogs, American toads, and mole salamanders. Floodplain forests also provide sheltered, riverside corridors for deer and migratory songbirds.

Current threats include alteration of natural hydrology through damming, loss of vegetated buffer, disturbance by trail cutting and the subsequent invasion of non-native plant species. In a 1997 statewide floodplain forest community inventory, non-native plant species were observed at all floodplain forest sites surveyed, but they appeared to be localized to areas where the canopy was opened, the herbaceous layer was cleared, and the soil was disturbed. Non-native plant species were most abundant is the island variant of major-river floodplain forests that are heavily used by campers and boaters for recreatioa Japanese knotweed (Polygonum cuspidatum) currently poses the greatest tlu^at to major-river floodplain forests because of its ability to spread rapidly and shade out all other herbaceous plants.
The natural hydrologic regime that created these ^)ecia] communities and their natural closed-canopy forest structure must be maintained. There are no truly effective ways to eradicate Japanese knotweed once it has established. The best way to avoid its spjread is to prevent its establishment by avoiding all clearing and disturbance within floodplain forest areas, particularly on the sandier banks.

Silver maple-green ash-American elm forests occurring on alluvial soils. Transitional floodplain forests are intermediate in vegetation composition and soils between major- and small-river types.
Transitional floodplain forests are known to occur on third-order or smaller tributaries of the Connecticut River, on portions of the Housatonic River, and in depressions within major-river floodplain forests of the Connecticut and Deerfield Rivers. Sites generally experience annual flooding. The severity of flooding, soil texture, and soil drainage of transitional floodplain forests is intermediate between major-river and small-river floodplain forests.

Transitional floodplain forests have a vegetation association intermediate between major-river and small-river floodplain forests. Silver maple {Acer saccharinum) is dominant in the canopy, but unlike in major-river forests, cottonwood {Populua deltoides) is typically absent. Similar to small-river forests, green ash {Fraxinus pennsylvamca) and American elm (JJlmus americana) are present. A shrub layer is generally lacking; however, saplings of overstory trees are common. Vines are abundant with hog peanut (Amphicarpaea hracteata) most common. Wood-nettle {Laportea canadensis) is not dominant, but it is present in low amounts, about 5-15% cover.

Habitat values for Associated Fauna:
Silver maple/green ash-dominated forests occurring on alluvial soils of small rivers and streams.
Small-river floodplain forests are known to occur on third-order or smaller tributaries of the Connecticut and Nashua Rivers, on small rivers of eastern Massachusetts where banks are low and overbank flooding occurs, such as the Ipswich, Assab^ Concord, Shawsheen, and Three Mile Rivers, and on edges of riverine island s of the Merrimack River. Annual flooding occurs, but the water volume and degree of scour are much less than in major-river floodplain forests. Soils are hydric silt loams and fme sand y loams with soil mottling within the top 60 cm [2 ft] and sometimes with a surface organic layer.
As in major-river and transitional floodplain forest types, silver maple (Acer saccharinum) is dominant in the overstory of small-river floodplain forests, but the understory more closely resembles that of red maple-alluvial swamp forests. Cottonwood (Populus deltoides) and red maple {Acer rubrum) are both typically absent in the canopy of small-river floodplain forest communities. Pin oak (Quercus palustris) is a common canopy associate in the Connecticut River basin, and river birch (Betula nigra) in the Merrimack River basin. Small-river floodplain forests have a more substantial shrub layer than both major-river and transitional types, but less than alluvial swamp forests. The shrub layer consists mainly of silky dogwood (Comus amomum) and buttonbush (Cephalanthus occidentalis). There is greater herbaceous plant diversity in small-river floodplain forests than in major-river and transitional types. Sensitive fern (Onoclea sensibilis) and false nettle (Boehmeria cylindricd) are most common, and associates include the moisture-loving plants, water hemlock (Cicuta maculata\ swamp candles (Lysimachia terrestris\ and water parsnip (Sium suave).
One association was described in Kearsley (1998): Type IV-Small-river floodplain forests (Acersaccharinum-Fraxinus pennsytvanica-Quercus pcdustris Association).

Mesic, deciduous hardwood forests of high alluvial terraces above the zone of annual flooding. This community type also occurs along riveibanks of high-gradient, northern rivers.
High-terrace floodplain forests occur on raised banks adjacent to rivers and streams, on steep banks bordering high-gradient rivers in the western parts of the state, on high alluvial terraces, and on raised areas within major-river and small-river floodplain forests. They are river-influenced and mesic, but they typically are not flooded annually as indicated by the presence of a distinct surface, soil organic layer. Soils are typically silt loams.
The canopy is a mixture of floodplain taxa, such as red and silver maple (Acer rubrum and A saccharinum), and mesic, deciduous hardwoods including sugar maple {A. saccharum), shagbark hickory {Carya ovata), black cherry {Primus serotina), American elm (Ulmus americana), and basswood {Tilia americana). Ironwood (Carpinus caroliniand) typically forms an open subcanopy and is a good indicator species of this conununity type. The shrub layer varies from sparse to well- developed with arrowwood {Viburnum dentatum), viaanybexxy {Viburnum lentago\ and winterberry {Ilex verticillata) most common mixed with variable amounts of non-native shrubs, including Jajianese barberry {Berberis thunbergif) and buckthorn {Rhamnus frtmgula, R. cathartica). The herbaceous layer is a mixture of the characteristic floodplain forest ferns— sensitive fern {Onoclea sensibilis) and ostrich fern {Kiatteuccia struthiopteris}-and rich upland herbs, such as Canada mayflower {Maianthemum canadense\ lady fern {Athyriumfilix-femina\ zigzag goldenrod {Solidago Jlexicaulis), white snakeroot {Eupatorium rugosum.\ jack-in-the-pulpit {Arisaema triphyllum) and bellwort {Uvularia sessilifola).

Most high terraces have been converted to agriculture. Remaining examples are typically small and disturb^ by selective logging and trail clearing. The lack of natural vegetated buffers make these communities highly susceptible to non-native plant invasions. Most known examples have non-native plant species comprising a substantial percentage of overall plant cover. Because these communities fall outside of wetland boimdaries, they are not subject to wetland regulations making them targets for selective logging and clearing for agriculture.
Removal of non-native ^jecies.

A veiriant of high-energy riverbanks characterized by open forests dominated by stunted sycamores and cottonwoods growing on sand y cobble bars.
Cobble bar forests are limited to cobble substrates that are deposited by high-energy rivers. They are more severely flooded and scoured than floodplain forests. More information is needed on the environmental setting and hydrologic regime of cobble bar forests.
Open canopy forests dominated by sycamore (Platanus occidentalis) with associated Cottonwood (Populus deltoides) and silver maple (Acer saccharinum). American elm (Ulmus americana) occurs in the subcanopy. Trees are generally younger than in other floodplain forest communities. More information is needed on this community type. In known examples on the Westfield River, exotic species are abundant in the understory. Most common are multiflora rose (Rosa multiflora), various exotic shrubby honeysuckles (Lonicera spp.X Oriental bittersweet (Celastrus orbiculata), and Japanese knotweed (Polygonum cuspidatum). Herbaceous species occur in the interstitial sand /silt between cobbles. Typical species include sensitive fern (Onoclea sensibilis\ false Solomon's seal (Maianthemum racemosa\ and horsetails (Equisetum spp.). Poison ivy (Toxicodendron radicans) and Virginia creeper (Parthenocissus quinquefolia) can be abundant More information is needed.

Graminoid- or shrub-dominated coastal community occurring in shallow basins (swales) between sand dunes.
Interdunal swales are low, shallow depressions that form between sand dunes along the coast. They occur as part of a dune system, and the best examples are complexes of numerous swales. Soils generally have a thin, about 1 cm, organic layer over coarse sand. The water regime ranges from seasonally flooded to permanently inundated
Interdunal swales range from unvegetated pools to graminoid-dominated to low shrub-dominated communities. The most common type is a low shrub community dominated by large cranberry (Vaccinium macrocarpon; often with greater than 90% cover) with lesser amounts of bayberry (Myrica pensyhanicd). Typical associates include various rushes (Juncus pelocarpus. J. canadensis, etc.), spatulate-leaved and thread-leaved sundews (Drosera intennedia and D.filiformis), beak sedges (Rhynchospora capitellata and K alba), yellow-eyed grasses (Xyris spp.X SL John's- worts (Hypericum spp.), southern bog clubmoss (Lycopodium adpressum\ and several orchid species such as rose pogonia (Pogonia ophioglossoides), grass-pink (Calopogon pulchellus), and nodding ladies'-tresses (Spiranthes cemua). Arethusa (Arethusa bulbosa) and ragged fringed orchis (Platanthera lacera) are two orchid species that occur occasionally. Graminoid-dominated swales are characterized by a mixture of rushes (Juncus spp.), beak-sedges (Rhynchospora spp.) and other graminoids. Some interdunal swales have large numbers of Plymouth gentian (Sabatia kennedyana). Scattered pitch pine (Finns rigida) and sheep laurel (Kalmia angustifolia) can also occur.
The coastal interdunal marsh/swale commvmity includes the six interdunal swale vegetation
associations that have been described for Massachusetts [Lundgren, 1998]. Those associations are:
Myrica pensylvanica-Vaccinium macrocarpon swale; Vaccinium macrocarpon-^nnm\.o\d swale
(variants = V. macrocarponScirpus pungens-Panicum virgatum swale; V. macrocarpon-
Rhynchospora capitellata swale); Juncus spp. (J. greenei, J. pelocarpus, J. canadensis, J. balticus)
swale; Juncus spp.-{Cyperus) swale; Scirpus pungens-Juncus swale; and Scirpus pungens-Triglochin
brackish swale.
Interdunal sv^es can function as vernal pool habitat if water remains standing for 2-3 months
and they lack fish; these swales provide important amphibian breeding habitat, particularly for toads,
including American, Fowler's, and spadefoot toads. Interdunal swales have a high habitat value to birds
and mammals for food, cover, and nesting sites.

Habitat values for Associated Fauna:
Tall graminoid/emergent herbaceous wetlands occurring on saturated, mucky mineral soils that are seasonally inundated and permanently saturated
Deep emergent marshes generally form in broad, flat areas bordering low-energy rivers and streams or along pond and lake margins. The soils are a mixture of organic and mineral components There is typically a layer of well-decomposed organic muck at the surface overlying mineral soil. There is standing or running water during the growing season and throughout much of the year. Water def>th averages between 6 in. and 3 ft. Deep emergent marshes are associated with shrub swamps, and the two commumties intergrade.
Tall graminoids, like broad-leaved cat-tail (Typha latifolia) and phragmites {Phragmites australis), often form extensive dense stand s. Narrow-leaved cat-tail (Typha angustifolia) occurs in more alkaline sites or in saline areas along roads [Weatherbee, 1996]. Other characteristic graminoids include wool- grass {Scirpus cyperinus), common threesquare {Scirpus pungens), Canada bluejoint (Calamagrostis canadensis var. canadensis), rice cut-grass (Leersia oryzoides), and tussock-sedge (Carex stricta). Herbaceous associates include arrow-leaf tearthumb (Polygonum sagittatumX bulblet water-hemlock (Cicuta bulbifera), swamp-candles (Lysimachia terrestris\ beggar-ticks (Bidens spp.), bedstraw (Galium spp.), common arrowhead (Sagittaria latifolia var. latifolia), slender-leaved goldenrod (Euthamia tenuifolia) and marsh-fern (Thelypteris palustris var. pubescens).

Grass, sedge, and /or rush-dominated wetlands on mucky mineral soils that are seasonally inundated and pennanently saturated.
Shallow emergent marshes occur in similar settings to deep emergent marshes, i.e. in broad, flat areas bordering low-energy rivers and streams, often in backwater sloughs, or along pond and lake margins. Unlike deep emergent marshes, shallow marshes commonly occur in abandoned beaver flowages, and in some states they are named "Abandoned beaver meadows" or "beaver flowage communities." The soils are a mixture of organic and mineral components. There is typically a layer of well-decomposed organic muck at the surface overlying mineral soil. There is standing or running waier during the growing season and throughout much of the year, but water depth is less than deep emergent marshes and averages less than 6 in.
Vegetation composition is similar to deep emergent marshes except tliat shorter grasses, sedges and rushes dominate. Cat-tails, phragmites, and wool-grass, the dominants of deep emergent marshes, can occur but are never dominant Tussock forming species, like tussock sedge (Carex stricta) and Canada bluejoint (Calamagrostis canadensis var. canadensis), often cover broad areas and form a hummock- hollow topography. Reed canary grass {Phalaris arundinacea) can also occur. It is common to see tussock sedge-dominated marshes in old beaver flowages mixed with scattered shnibs like alder and spiraea. The shallow water typically has a mixture of bur-reeds (Sparganium spp.X sedges (Carex spp.), and rice cut-grass (Leersia oryzoides). Floating leaved plants, like the water-lilies (Nymphaea odorata and Nuphar spp.X and submergents, like pondweeds (Potamogeton spp.), occur in open areas, and duckweed (Lemna spp.) is abundant in still water. Based on species composition alone, it can be difficult to differentiate shallow emergent marshes and wet meadows, but they occur in different physical settings and hydrologic regimes [see concept description for wet meadows. More community data are needed on these communities to determine the indicator species of each.
No associations have been described in Massachusetts.
Shallow emergent marshes are excellent habitat for muskrats. As with deep emergent marshes shallow emergent marshes provide important habitat for frogs and newts.

Graminoid/emergent herbaceous communities that are similar to deep and shallow emergent marshes except that they are temporarily rather than seasonally flooded. The soil is saturated during the growing season but not generally inundated Repeated disturbance, usually from grazing or mowing, keeps these communities opea
Wet meadows occur in lake basins, wet depressions, along streams, and in sloughs and other backwater areas with impeded drainage along rivers. The mucky mineral soils are permanently saturated and flood occasionally, standing water is not present throughout the growing season as in deep and shallow emergent marshes. As these communities flood only temporarily, continued disturbance is necessary to prevent encroachment by woody plants. More information is needed on the physical and biological characteristics of wet meadow and marsh communities.
Tussock-forming sedges, such as tussock-sedge (Carex stricta) or marsh-sedge {Carex lacustris), are often dominant, with over 50% of the cover, with variable proportions of other graminoids and herbaceous species. Canada bluejoint {Calamagrostis canadensis var. canadensis\ wool-grass (Scirpus cyperinus), slender woolly-fruited sedge (Carex lasiocarpa var. americana\ slender spike-sedge (Eleocharis tenuis), stalked wool-grass {Scirpus pedicellatus\ rice cut-grass (Leersia oryzoides), and brown beak-sedge {Rhynchospora capitellata) are typical of wet meadows. Characteristic herbaceous associates include erect water smartweed (Polygonum amphibium var, emersum), pickerel-weed (Pontederia cordata var. cordata), river-horsetail (Equisetum fluviatile), nodding bur-marigold (Bidens cemua\ spotted joe-pye- weed (Eupatorium maculatum\ northern blue flag (Iris versicolor), and swe^ flag (Acorus calamus). Calcareous wet meadows have calciphihc ^jecies, including red-footed spike- sedge (Eleocharis erythropoda\ delicate sedge (Carex leptalea\ fen-sedge (Carex tetanica), and beaked-sedge (Carex utriculata). More information is also needed on calcareous wet meadows in order to clarify there relationship to calcareous sloping fens and calcareous seepage marshes [both of which are described in Uie calcareous peatlands section due to their accumulation of peat]. Wet meadows Jire very closely related to shallow emergent marshes, but typically have more uniform vegetation, i.e. often a single sedge species dominates. Wet meadows are called "sedge meeidows" in many other states, but "wet meadow" is used in Massachusetts because of known occurrences of meadows dominated by rice cut-grass and other non-sedge species.
No associations have been described in Massachusetts.
Wet meadows can ftmction as vernal pool habitat if water remains standing for 2-3 months; these areas provide important amphibian breeding habitat

SCIRPUS TORREYI
Graminoid/emergent herbaceous or mixed shrub/herbaceous communities that are restricted to small, usually less than five acres, seasonally inundated, kettle depressions in sand y glacial outwash.
Kettlehole wet meadows are a variant of wet meadows that are restricted to glacial kettleholes in sand y outwash soils that have seasonal water level fluctuations. They are seasonally inundated by local runoff and ground water fluctuations, and they typically have no inlet or outlet For most of the summer, they look like shallow ponds, but by late summer they are covered by emergent vegetation. Soils are typically shallow, mucky peats. Deep peat does not develop due to the seasonal drawdown of water. The hydrology of kettlehole wet meadows is similar to coastal plain ponds. Both are characterized by a series of plant associations occurring along a gradient from the higher, drier margins to the lower, wetter centers.
Sedges and rushes are dominant, and characteristic species include Canada rush (Jimcus canadensis), pondshore rush (Juncus pelocarpus), bayonet rush (Juncus militaris\ needle spike sedge (Eleocharis acicularis). Small's spike sedge (Eleocharis smallii), Torrey's bullsedge {Scirpus torreyi) and various sedge {Carex) species. Shorter plants, like pipewort (Eriocaulon aquaticum\ are found growing beneath the cover of sedges and rushes. Grasses, such as creeping bent grass (Agrostis stolonifera\ and some broad-leaved emergents, including arrowhead (Sagittaria engelmanniana), nodding bur-marigold (Bidens cemua\ beggar's ticks (Bidens tripartita) and conunon SL John's wort (Hypericum perforatum), also occur. The wettest, muckiest areas have floating-leaved aquatic plants, including white water lily {Nymphaea odorata) and meimaid-weed (Proserpinaca palustris). When water levels are high, mannagrass (Glyceria pallida and G. acutifolia) is common, with yellow pond-lily (Nuphar variegata) and pickerel-weed (Pontederia cordata) occurring in deeper water. Kettlehole wet meadows are typically fringed with shrubs, such as leatherleaf (C/jamaec/ap/j/ie calyculata), high-bush blueberry (Vaccinium corymbosum), buttonbush {Cephalanthus occidentalis) and water willow (Decodon verticillatus), aivi with trees such as tupelo (Nyssa sylvatica) and red maple {Acer rubrum). Conmion meadow-beauty (Rhexia virginica) and various species of sphagnum moss (Sphagnum spp.) also grow along the edges. Kettlehole wet meadows are best visited in the late-summer when water levels are down, and the basin is covered by a dense growth of narrow-leaved emergents.
No associations have been described in Massachusetts.
Kettlehole wet meadows can function as vernal pool habitat if water remains standing for 2-3 months; these areas provide important amphibian breeding habitat The sedges, bulrushes and grasses of kettlehole wet meadows provide a food resource for waterfowl and other marsh birds.

There are currently three tracked sites, one in Douglas State Forest in Douglas and two in Minuteman National Park in Concord. More sites undoubtedly exist
Alterations to mitural water-level fluctuations. The sites for which we have vegetation data have surprisingly few non-native plant ^)ecies, and exotics may not currently threaten these communities.
More information is needed on the jjhysical and hydrological processes associated with Kettlehole wet meadows in order to make educated management recommendations. It is known that seasonal water level fluctuations play an important role in the occurrence of the commimity. Spring high-water levels prevent encroachment of woody shrubs and trees, and late-summer low- water levels allow characteristic narrow-leaved emergents to appear. Any alteration in natural water level fluctuations, such as groundwater withdrawal, would negatively affect the community. Inland Basin Marshes may be prone to burning during low water periods, but the role of fire in commimity dynamics is not known.

COASTAL PLAIN PONDSHORE
CP2A0B1200 S2 Yes
Concept: Herbaceous communities of exposed pondshores, most commonly in southeastern Massachusetts in areas of oak and
oak pine forests, characterized by a distinct coastal plain flora.
Environmental setting: Shallow, highly acidic groimdwater ponds in glacial outwash, usually with no inlet or outlet Water rises and falls with changes in the water table, typically leaving an exposed shoreline in late summer. In wet years, the pondshore may remain inundated. Substrate varies from sand - cobble to muck.
Vegetation Description: Vegetation zonation is correlated with flooding regime. A characteristic zonation pattern from dry to waterline, is as follows: 1 . upland oak forest, 2. Shrub border dominated by highbush blueberry {Vaccinium corymbosum) associated with sweet pepperbush (Clethra alnifolia), and green briar {Smilax rotundifolia\ 3. Emergent exposed pondshore dominated by coastal plain flat-topped goldenrod (Euthamia tenuifolid), pondshore rush (Juncus pelocarpus), rose coreopsis (Coreopsis rosea) and golden pert {Gratiola aurea\ with beaksedge (Rhynchospora spp.), lance-leaf violet (Viola lanceolata\ and dwarf SL John's- wort (Hypericum mutiluni), 4 Semip)ermanently flooded zone characterized by one or more of the following: bayonet rush (Juncus militans), spike-sedge (Eleocharis ^p-X pipewort (fnocaw/on aquaticum), and 5. Hydromorphic rooted vegetation in deeper water including yellow water-lily (Nuphar variegata), white water-Uly (Nymphaea odorata) and Robbins' spike-sedge (Eleocharis robbinsii). Not every pond has every zone, and zones vary in wiAh and species composition from year to yeeir. Coastal plain pondshores have an abundance of state-protected eind globally restricted rare plants.
Associations: USNVC/TNC coastal plain pond associations include plot data from Massachusetts coastal plain pondshores.
Habitat values for Coastal plain pondshores and ponds provide habitat for at least 43 rare animal and plant species.
Associated Fauna: Coastal plain pondshores are important habitat for over 45 ^)ecies of dragonflies and damselflies. They are also important habitat for painted, musk, spotted, snapjping, and the federally endangered Plymouth red belly turtles. Larger ponds are used by migrating and wintering waterfowl, including common and hooded mergansers, goldeneye, and bufllehead. Coastal plain ponds support warm-water flsh and freshwater mussels.

Threats: Multiple threats affect coastal plain pondshore communities. The greatest threat is from overdevelopment of
coastal Massachusetts which impiacts pondshores directly through housing and recreation and indirectly through water withdrawal. Shrub and tree encroachment threaten pondshore vegetation in areas with heavy water withdrawal.
Management needs: Natural hydrology needs to be maintained. Periodic high water prevents tree / shrub encroachment, and seasonal low water is necessary to exp>ose the pondshore. Vehicle use should be prohibited along pondshores.

Sparsely vegetated herbaceous community dominated by low, usually annual herbs occurring on muddy streamsides or in shallow water of river backwaters and old oxbow ponds.
Shallow water or open mud flats along streams, in backwaters, abandoned channels, lagoons, and oxbow ponds. Inundation by spring floods does occur, and the mucky, silty mineral soils are poorly drained.
Although often sparsely vegetated, mudflats typically have a high species richness (i.e. number of species). Winged {Kiimulus alatus) and long-stalked (Mimulus ringens) moiUcey-flowers are good indicator species. Large and lesser water-plantains {Alisma plantago-aquatica var. americanum and var. parviflorum), arrowheads (Sagittaria spp.X arrow-arum {Peltandra virgimca\ and bur-reeds (Sparganium spp ) are often dominant Other associated species include sensitive fern (Onoclea sensibilis\ false nettle (Boehmeria cylindrica), clearweed {Pilea pumild), water-hemlock {Cicuta maculata\ sweet flag {Acorus americcmus\ wild calla {Calla palustris), water-parsnip (Sium suave), ditch-stonecrop {Penthorum sedoides\ water-purslane {LAutwigia palustris), awned sedge (Carex crinita), river horsetail (Equisetumfluviatile\ smartweeds (Polygonum spp), and duckweeds {Lemna spp.). Floodplain forest trees, such as silver maple (Acer saccharinum) and American elm (Ulmus americana), often overhang these communities providing partial cover.

Mixed herbaceous community occurring on rocky edges of rivers where flood and ice scour maintain an open community and groundwater discharge provides mineral eiuichment
Riverside seeps occur at the base of steep riverbanks where groundwater seeps out of the bottom of the upland slope. MineraJ-rich seepage leads to a high species diversity and periodic flooding from the river helps to prevent woody shrub encroachment. Calcareous (limey) riverside seeps occur along the Connecticut River in New Hampshire and Vermont and are characterized by their fen-like conditions and calcium-loving plant species, particularly false asphodel {Tofieldia glutinosa), Kalm's lobelia {Lobelia kalntii), and grass-of-Pamassus (Pamassia glauca). Comparable riverine limey seep communities are not known to occur in Massachusetts [Motzkin 1993]. The known occurrences of riverside seeps in Massachusetts along the Westfleld and Deerfleld Rivers lack the calcareous conditions and indicators of limey seeps to the north. More informaticMi is needed on the water chemistry of riverside seeps in Massachusetts, and on the range of conditions and species assemblages present in the Commonwealth. Riverside seeps are often associated with riverside outcrop communities and high-energy riverbank, i.e. gravel bar, communities.
The wettest spots are typically mossy with a mixture of herbs and sedges. Characteristic herbs include spotted Joe-pye-weed (Eupatorium maculatum), honeset (Eupatoriunt perfoliatum\ orange jewelweed (impatiens capensis), and fringed loosestrife {Lysimachia ciliata). Yellow monkey flower (Kiimulus moschatus\ Canadian bumet (Sanguisorba canadensis), and golden alexanders (Zizia aurea) are indicative of minerotrophic conditions, and they are good indicator species of the community type. The non-native plants, colt's foot {Tussilago farfard) and purple loosestrife {Lythrum salicaria\ can also be abundant in the community. Graminoids known to occur in riverside seeps include wool-grass (Scirpus cyperinus), marsh-nish (Juncus canadensis), soft rush {Juncus ejfusus), green-fruited bur-reed (Sparganium erectum), sallow sedge {Carex lurida\ northern awned-sedge {Carex gynandra), and seep-sedge {Carex scabrata). The vegetation composition described here is probably limited to sites occurring in the western part of the state.

Open herbaceous/graminoid communities occurring on sand y or silty mineral soils of river and streambanks that do not experience severe flooding or ice scour.
Low-energy rivers are smaller, low-gradient rivers that do not experience severe flooding. The riverbanks are generally sand y or silty. They lack the cobble substrate of high-energy areas and the muddy soils of open mud flats. These communities occur on mineral soil rather than the peaty or mucky soil that characterizes alluvial marshes and wet meadows. More information is needed.
The species composition is variable but the structure is always an open mixture of herbaceous and graminoid species with occasional scattered shrubs and trees at the inlimd margin. Common species are reed canary-grass (Phalaris arundinacea\ which can be dominant, cockspur-grass {Echinochloa muricata\ fall panic-grass (Panicum dichotomijlonwi), rice cut-grass {Leersia oryzoides), Canada bluejoint {Calamagrostis canadensis var. canadensisX SL John's-wort (Hypericum spp.), smartweeds (Polygonum spp.), and various goldenrod species (Solidago spp.). Species typical of disturbed areas, such as cocklebur (Xanthium strumarium var. canadense) are common in tx)th high and low-energy riverbank communities. Low-energy riverbanks are more sparsely vegetated than marshes and w^ meadows.

Habitat values for Associated Fauna:
Sparse, open herbaceous/graminoid conununities occurring on cobble and sand substrates of steqv gradient, fast-flowing rivers that experience severe flooding and ice scour.
High-energy riverbank enviroiunents are created by the alluvial deposition of cobbles, sand and silt during high spring flood events, and they are shaped by continued armual flood events and winter ice scour. DitTerences in severity of scouring and flooding create a gradient of substrate types from the river's edge to the upland transition. Scouring and flooding are most intense at the river's edge, especially the upstream end of riverine islands, which receive the full force of ice floes and debris- laden flood waters. In the fast-moving water, only large cobbles are heavy enough to drop out of suspension. As the water crosses the cobblebar it slows down and smaller piarticles drop out, creating a continuum from cobbles and pebbles to sand and silt. That continuum correlates to a the change in vegetation communities.
Vegetation zonation within high-energy riverbank commimities corresponds to substrate type and severity of flooding. On op)en cobbles, false dragonhead (Physostegia virginiana), cocklebur (Xanthium strumarium), beggar's ticks (Bidens spp.) and lady's thumb {Polygonum persicaria, an exotic) are dominant As the percent sand increases, water horsetail (Equisetumjluviatile) and clawing dogbane {Apocynum cannabinum var, hypericifolium) occur, and there is typically a distinct baivl of switchgrass (Panicum virgatum). In the still sandier areas, mixed grasslaikl s of switchgrass, big and little bluestem (Andropogon gerardii and Schizachyrium scoparium\ Indian grass (Sorghastrum nutans), and goldeiu'ods {Solidago spp.) are found. Intense flooding and ice scour prevents estabUshment and growth of trees or tall shrubs; cobble bars that do have a tree canopy (cover >30%) are classified separately as cobble bar forests Short shrubs such as shadbush {Amelanchier sanguinea\ silky dogwood (Contus amomum), sand bar willow {Salix exigua) and sand bar cherry {Prunus pumila var. depressa) form a vegetation zone on the sandiest sections, typically bordering floodplain forests that occupy siltier soils.

Excellent examples of the community type in Massachusetts can be found on the upstream ends of the Sunderland Island s north of Sunderland Bridge on the Connecticut River.
The two major threats to high-energy river communities are alteration of natural flooding regimes due to river control projects and the invasion of non-native plant ^jecies. High-energy riverbank environments are creeited by severe flooding and ice scour, and these natural disturbance regimes are necessary to maintain the community. Because of the community's exposure to flooding, it is susceptible to colonization by exotic plants, such as purple loosestrife (Lythrum salicaria) and lady's thimib (Polygonum persicaria), that have their seeds washed in from upstream sources. Trampling from campers and boaters creates further disturbance and favors fast-growing exotic plants.
Where possible, highly invasive exotic plants should be mechanically removed. Management to reduce non-native plant ^>ecies throughout a drainage basin will help preserve the native plant communities of high-energy riverbanks. Natural hydrologic regimes should be maintained.
Good information available for Connecticut and Deerfield Rivers. Inventories needed for Westfield and Farmington Rivers. |

Trampling from campers and boaters negatively impacts both the plant and animal communities of riverine pointbar and beach communities. Alterations to normal flooding regimes can impact alluvial deposition, resulting in expansion or reduction of beach size.
Cocklebur (Xanthium stnanarium) and Japanese knotweed {Polygonum cuspidatum) removal may be necessary from areas used as larval habitat by Puritan tiger beetles. The two species grow quickly and shade large areas thus eliminating habitat for the tiger beetles. More information is needed to assess the management needs for pointbars and beaches.

Shrub-dominated wetlands occurring on mineral or mucky mineral soils that are seasonally or temporarily flooded.
Shrub swamps are common and widespread. They occur in basin depressions, at pond margins, and along river and streamsides. They can be found in any flat area vviiere the water table is at or above the soil surface for most of the year. Soils are generally well-decomposed organic mucks that are permanently saturated but only seasonally or temporarily inundated. Shrub swamps are often found in the transition zone between emergent marshes and swamp forests. More information is needed on their physical characteristics.
Shrub swamps are highly variable communities that probably can be divided into several types; however, there is currently not enough information available to separate vegetation types. Shrub swamps typically have a mixture of the following shrub species: speckled alder (Alnus incana ssp. rugosa\ smooth alder (Alnus serrulata\ highbush blueberry (yaccinium corymbosum), meadowsweet {Spiraea alba var. latifolia), buttonbush (Cephalanthus occidentalis\ winterberry {Ilex verticil lata), sweet gale {Myrica gale\ swamp azalea {Rhododendron viscosum\ silky dogwood {Comus amomumX northern arrow- wood {Viburnum dentatum var. lucidum\ maleberry {Lyonia ligustrina), and the non- native shrub European alder-buckthom {Rhamnus frangula). Scattered red maple {Acer rubrum) or gray birch {Betula populifolia) saplings also occur. Richer shrub swamps in areas with circumneutral water are often dominated by spicebush {Undent benzoin). Some shrub swamps are dominated by a single ^)ecies, such as black willow {Salix nigra) riverside thickets [which may best be included with floodplain forests], highbush bluebeiry thickets, or buttonbush swamps. Highbush blueberry thicks that occur on peat are described separately in the peatlands section, with more data, other types may also be split off and described as distinct commimity types. Since shrubs often form dense thickets, the herbaceous layer of shrub swamps is often sparse and species-poor. A mixture of the following species is typical: common arrowhead {Sagittaria latifolia var. latifolia), skunk cabbage {Symplocarpus foetidus\ cirmamon fern (Osmunda cinnamomea), sensitive fern (Onoclea sensibilis), arxl royal fem (Osmunda regalis), sedges {Carex spp.X and Sphagniun spp. moss. More inventory work is needed.
No associations have been described in Massachusetts.
Shrub swamps often function as vernal pool habitat in sections that have extended periods of ponding {2-3 months) and lack fish; these sections provide important amj^'bian breeding habitat

Habitat values for Associated Fauna
Open, sedge-dominated wetlands occurring on slight to moderate slopes where there is calcareous groundwater seepage. Calcareous slopmg fens are the most nutrient- and species-rich of the three calcareous fen communities described in Massachusetts. They are rare ^)ecies "hot spots" with many associated rare plant and animal species.
Extremely rich fen communities occurring in areas that are slightly to moderately sloping with calcareous groundwater seepage that is often visible as distinct rivulets. Where there is heavy groundwater discharge, the mineral soil is exposed There can also be small hummocks of organic matter accumulation. Sites that are more highly disturbed have less woody shrub growth.
Low graminoid/herbaceous communities dominated by sedges, such as inland prickly sedge (Carex interior), dehcate sedge (C. leptalea\ yellow sedge (C./lava\ and porcupine-sedge (C. hystericina). Typical herbaceous associates include grass-of-Pamassus (Pamassia glauca\ rough-leaved goldenrod (Solidago patuld), fen-goldenrod {S. purshii\ and marsh-fern {Thelypteris palustris var. pubescens). There is a sparse tree and shrub cover. Common trees and shrubs include wtiite pine (Pinus strobus\ tamarack (Larix laricina\ shrubby cinquefoil (PentaphylloidesJJoribunda), autumn-willow (Salix serissima), and alder-leaf buckthorn (Rhamnus alnifolia).
Seven calcareous fen vegetation associations have been described for western New England and adjacent New York state [Motzkin, 1994]. Calcareous sloping fens are equivalent to Motzkin's Carex interior-Carex leptalea-Carex flava type [Group HI].
Calcareous sloping fenscan function as vernal pool habitat if water remains standing for 2-3 months; these sections provide important amphibian breeding habitat Several state-protected rare turtle species inhabit calcareous sloping fens. Regionally rare ant species are also known to occur in this commimity type.

Several examples in Berkshire County. Massachusetts contains some of the best examples of calcareous fern in New England.
Changes in groundwater quality and quantity, and any human activities that disturb the vegetation, substrate, or water supply. In disturbal areas, cattails may displace calcium-loving species. Beaver activity threatens calcareous fen communities by altering surface water chemistry. There is evidence to suggest that ponding of water by beaver dams may increase the water's relative acidity possibly due to the accumulation of organic acids or to dilution from acid rain [Motzkin, 1992].
Fires, grazing, and /or mowing may be necessary to maintain open fen habitats. More information is needed.

Mixed herbaceousf'graminoid/shrub wetlands that experience some calcareous groundwater seepage. Calcareous seepage marshes are intermediate in richness of the three calcareous fen communities described in Massachusetts.
Marsh community with some calcareous seepage. This commimity type is found in a variety of physical settings— in basins, in canopy gaps in rich forested swampks, in current or former beaver drainages, or in level to slightly sloping sites associated with sloping fens. There is typically 50-200+ cm of moderate to well-decomposed organic sediments.
Open emergent community with scattered shrubs, such as swamp-birch (Betula pumila), hoary willow (Salix Candida), meadowsweet {Spiraea latifolia), and poison-sxmiac (Toxicodendron vemix). The herbaceous layer is a mixture of typical marsh species, including marsh sedge (Carex lacustris\ tussock sedge (C. strictd), and marsh fern {Thelypteris palustris). Other characteristic ^jecies are phragmites (Phragmites australis), cat-tails (Typha angustifolia and T. latifolia\ purple loosestrife (Lythrum salicaria\ Labrador-bedstraw {Galium labradoricum), and swamp loosestrife {Lysimachia thyrsijlora). Calcareous seepage marshes are distinguished from other emergent marshes by the presence of calciphilic {calcium-loving) species, including swamp birch, hoary willow, shrubby cinquefoil {Pentaphylloides floribunda\ and fen-bedstraw {Galium labradoricum).
Seven calcareous fen vegetation associations have been described for western New England and adjacent New York state (Motzkin, 1994]. Calcareous seepage marshes include four of Motzkin's associations [all grouped in his Group II]: 1 . Betula pumila type with a well-developed shrub layer, 2. Carex lacustris type which lacks extensive woody cover, 3. Carex stricta type with higher frequency and cover of C. stricta, and 4. Typha angustifolia-Carex lasiocarpa type which has less Pentaphylloides floribunda than the other types.
Calcareous seepage marshes can function as vernal pool habitat in sections that have two to three months of ponding and lack fish; these sections provide important amphibian breeding habitat

Sedge-shrub peatlands occurring in well-defined basins that have calcareous groundwater, and sometimes surface water, inputs. Calcareous basin fens are the least rich of the three calcareous fen communities described in Massachusetts.
Calcareous basin fens occur in well-defined basins with deep organic sediments, permanently saturated conditions, and consolidated or floating, sedge-dominated organic mats. They are the least rich (with respect to water chemistry) of the fen communities; Based on sediment core information from Kampoosa fen this community appears relatively stable over time (existed at the site for a few thousand years) and there is no evidence of rapid infilling or texrestrialization. The Carex lasiocarpa-Cladium mariscoides type is less mineral rich than the Carex aquatilis type. More work is needed to understand the range of hydrology and water chemistry of intermediate peatlands, e.g. what physical properties differentiate calcareous basin fens from acidic graminoid fens?
Sedge-dominated peatlands with sparse shrub layers. The dominant species are slender woolly-fruited sedge {Carex lasiocarpa var. americana), water-sedge (C. aquatilis\ shrubby cinquefoil (Pentaphylloides floribunda), and sweet-gale (Myrica gale), which are associated with typical bog/acidic fen species such as pitcher plant {Sarracenia purpurea), large cranbeny (Vaccinium macrocarpoh), round-leaved sundew (Drosera rotundifolia\ and white beaksedge (Rhynchospora alba). Dominant bryophytes are Campylium stellatum, Calliergonella sp^. and Sphagnum spp. Calcareous basin fens diJOfer from calcareous seepage marshes by lacking swamp-bireh (Betula pumila\ hoary willow (Salix Candida), and typical marsh species like marsh fern (Thelypteris palustris) and tussock sedge {Carex stricta). Calcareous basin fens are similar to acidic graminoid fens in structure and species composition, but they have calciphihc species, such as shrubby cinquefoil or grass of pamassis. More work is needed the classify the vegetation associations of these intermediate peatland community types.
Seven calcareous fen vegetation associations have been described for western New England and adjacent New York state [Motzkin, 1994]. Calcareous basin fens include two of Motzkin's associations [both grouped in his Group I]: the Carex lasiocarpa-Cladium mariscoides type and the Carex aquatilis type.
Calcareous basin fens can function as vernal pool habitat in sections that have two to three montlis of ponding and lack fish; these sections provide important amphibian breeding habitat

Mixed graminoid/heibaceous acidic peatlands that experience some groundwater and /or surfzice water flow but no calcareous seepage. Shrubs occur in clumps but are not dominant throughout.
Acidic graminoid fens are sedge-Zsphagnum-dominated peatlands that are weakly minerotrophic [mineral-rich]. Acidic graminoid fens typically have some surface water inflow and some groundwater connectivity. Inlets and outlets are usually present, and standing water is present throughout much of the growing season Peat mats are quaking and often unstable. More information is needed on peat characteristics and hydrology.
Acidic graminoid fens are diflerentiated from acidic shrub fens by their abundance of graminoid species and lack of extensive \eaithcT\e:a[ (Chamaedaphne calyculata) and water-willow {Decodon verticillatus). Beaked sedge {Carex utriculata) and slender woolly-fruited sedge (Carex lasiocarpa var. americana) are often dominant. Other good indicator species are white beak-sedge (Rhynchospora alba), twig-sedge {Cladium mariscoides), and pondshore-rush {Juncus pelocarpus). Characteristic herbaceous species include airow-arum (Peltandra virginica) and rose pogonia (Pogonia ophioglossoUes). Large cranberry (Vaccinium macrocarpon) can be abundant. There is piatchy tree and shrub cover, including swamp azalea {Rhododendron viscosum\ sweet pepper-bush (Clethra alnifolia\ poison sumac (Toxicodendron vemix\ red maple {Acer rubrum), and Atlantic white cedar {Chamaecyparis thyoides). Coastal sites also have bayberry {Kfyrica pennsylvanica).

Shrub-dominated acidic peatlands characterized by a mixture of primarily deciduous shrubs. Acidic shrub fens exp)erience some groundwater and /or surface water flow but not calcareous seepage.
Acidic shrub fens are less acidic and nutrient-poor than level bogs; they appear to have more siuface water inflow and some groundwater connectivity. Acidic shnib fens are typically found along wet pond margins in the eastern half of the state, but they also characterize many wet pond margins in northern Worcester County [e.g. Cheshire and Lincoln Ponds, Ashbumham] and the Berkshires [Horseshoe- Mud Pond Bog, Otis]. More information is needed to identify the physical, geochemical, or hydrological differences between acidic shrub fens and acidic graminoid fens.
Acidic shrub fens are composed primarily of low-growing, interwoven shrubs with jiatches of Sphagnum moss growing at the shnib bases. Evergreen and deciduous shrubs occur, typical species include leatherleaf, water-willow (Decodon verticillatus\ sweet-gale (Kfyrica gale), meadow-sweet (Spiraea alba var. latifolia), sweet-pepperbush (Clethra alnifolia), and alder {Alnus ^p.). Scattered red maples {Acer rubrum) and Atlantic white cedar {Chamaecyparis thyoides) can also occur. There is a limited number of herbaceous q)ecies, including St John's- wort {Hypericum spp.) and arrow- weed {Sagittaria spp.). These fissociations are similar in structure to dwarf ericaceous shrub bogs, but they are wetter with a less well-developed sphagnum mat
One association has been described in Massachusetts: the E)ecodon verticillatus-Chamaedaphne calyculata-Myrica gale acidic shrub fen association [TYPE F; described in Kearsley, 1999].
Acidic shrub fens can function as vernal pool habitat if water remains standing for 2-3 months; these areas provide important amphibian breeding habitat

Habitat values for Associated Fauna:
Herbaceous/graminoid peatlands that occur at the upland edges of ocean tidal marshes. The combination of upland freshwater seepage and infrequent salt or brackish overwash produces a mixed plant conununity of freshwater and estuahne species.
Sea-level fens occupy the interface between estuahne marshes and upland seepage slopes, and therefore have a distinct species assemblage including both estuarine and palustrine species. There are two hydrologic influences: acidic freshwater seepage from the uplands and periodic salt or brackish overwash from the adjeicent marsh. Both are needed to produce the combination of species observed in sea-level fens.
Probable community type in Massachusetts, but vegetation descriptions are lacking. There are two probable occurrences reported from Martha's Vineyard that have saltmarsh spike-sedge {Eleocharis rostellata) co-occurring with acidic fen species. Plot data are needed. Ludwig (1995) described the flora of sea-level fens from Virginia, Delaware, New York, and Connecticut. He described three diagnostic species: saltmarsh straw-sedge {Carex hormathodes\ saltmarsh spike-sedge {Eleocharis rostellata), and saltmarsh-threesquare {Scirpus americanus). Other common species include; New York aster {Aster novi-belgif), twig-sedge {Cladium mariscoides\ spjatulate-leaved sundew {Drosera intermedia), Canada rush {Juncus canadensis), pondshore-rush {Juncus pelocarpus), swamp-candles {Lysimachia terrestris), common reed {Phragmites australis), white beak-sedge {Rhynchospora alba), swamp-rose {Rosa palustris), common threesquare {Scirpus pungens), poison ivy {Toxicodendron radicans), and marsh SL John's-wort {Triadenum virginicum). (State Historical, deceitful spike-sedge {Eleocharis fallax) listed as common in more southern occurrences.]

Acidic dwarf ericaceous shrub peatlands, generally with pronounced hummock-hollow topography. Level bogs are the most acidic and nutrient-poor of Massachusetts' peatland communities.
Level bog communities receive little or no streamflow and they are isolated from the water table, making them the most acidic and nutrient-poor of peatland communities. The pH of level bogs is in the range of 3 to 4. Level bogs develop along pond margins, at the headwaters of streams, or in isolated valley bottoms without inlet or outlet streams.
Level bogs are characterized by a mixture of tall and short shrubs that are predominantly ericaceous (i.e. members of the Heath family). Lcaihcrleaf (Chamaedaphne calyculata) is dominant Other typical ericaceous shrubs include rhodora (Rhododendron canadense\ sheep laurel {Kalmia angustifolia\ bog laurel {Kalmia polifolia\ bog rosemary {Andromeda polifolia var. glaucophylla\ Labrador tea {Ledum groenlandicum\ and low-growing large and small cranberry (KacCT/i/um macrocarpon and V. oxycoccus). Scattered, stunted coniferous trees, primarily tamarack (Larix laricina) and black spruce (Picea mariana), occur throughout A mixture of specialized bog plants grow on the hummocky Sphagnum surface, including carnivorous pitcher plants {Sarracenia purpurea) and sundews {Drosera rotundifolia and D. intermedia).
Five associations have been described in Massachusetts. They are: 1 . Vaccinium corymbosum- Rhododendron viscosum tall shrub bog find bog border association [TYPE A in Kearsley, 1999], 2. Vaccinium corymbasum-Rhododendron canadense-Ledum groenlandicum tall shrub bog association [TYPE B in Kearsley, 1999], 3. A Chamaedaphne calyculata-Kalmia polifolia-Maianthemum trifolium dwarf ericaceous shrub bog association [TYPE C in Kearsley, 1999], 4 Chamaedaphne calyculata dwarf ericaceous shrub bog association [TYPE D], and 5. Vaccinium oxycoccus-Rhynchospora alba- Utricularia comuta open sphagnum lawn association [TYPE E).
The high acidity and low oxygen content of the water make level bogs inhospitable to many reptiles, fish, and amphibians. However, several of the state's protected rare animal species are found in level bogs. Moats or pools associated with level bogs can provide important amphibian breeding habitat and function as vernal pools if they have two to three months of ponding and lack fish.

KETTLEHOLE LEVEL BOG
CP2B0C1100 S2 Yes
A variant of level bogs occurring in kettle dq)ressions in sand y glacial outwash. Vegetation is typically zoned in rings.
Kettlehole level bogs are a subset of level bogs that occur in iceblock depressions (commonly called kettleholes) in sand y glacial outwash. They are typically small (< 3 acres\ round, and they lack inlets and outlets.
Kettlehole level bogs have similar vegetation to level bogs, except that the vegetation is typically in a ringed zonation pattern. Often the outer wet moat is dominated by a mixture of highbush blueberry (Vaccinium corymbosum) and swamp azalea {Rhododendron viscosum) bordered to the interior by a ring of rhodora {Rhododendron canadense). The mat has a mixture of tall and short shrubs that are predominantly ericaceous (members of the Heath family). heaihaXaS {Chamaedaphne catyculata) is dominant Other typical ericaceous shrubs include rhodora, sheep laurel {Kalmia angustifolia), bog laurel {Kalmia polifolid), bog rosemary {Andromeda polifolia var. glaucophylla\ Labrador tea {Ledum groenlandicum\ arvd low-growing large and small cranberry {Vaccinium macrocarpon and V. oxycoccus). Scattered, stunted coniferous trees, primarily tamarack (Larix laricina) and black spruce (Picea mariana) occur throughout. A mixture of specialized bog plants grow on the hummocky sphagnimi surface, including carnivorous pitcher plants {Sarracenia purpurea) and sundews {Drosera rotundifolia and D. intermedia). Many of the kettlehole bogs observed in the state have drier and more stable sphagnum mats than level bogs not in kettleholes, and they have abundant bog laurel and three- leaved Solomon's seal {Maianthemum trifolium).
One association has been described in Massachusetts: the Cbamaedaphne calycuIata-Kalmia polifolia- Maianthemimi trifolium dwarf ericaceous shrub bog association [TYPE C in Kearsley, 1999].

Acidic peatlands dominated by dense highbush blueberry bushes on hummocky sphagnum moss.
Highbush blud)eTTy tliickets appear to occur in areas that are wetter and more mineral- enriched than dwarf shrub level bog communities. Tall shrub thickets are generally flooded in spring and early summer, but water levels drop below the soil surface by late summer or early fall. The sphagnum mat is variable; it can be paichy and unstable or thick and stable. Many of the known examples occupy kettleholes.
Highbush blueberry thickets are tall shrub peatlands dominated by dense highbush blueberries {Vaccinium corymbosum). Swamp azalea {Rhododendron viscosum) is a common associate, and typical short shrubs include sheep laurel {K. angustifolid), leathalesS (Chamaedaphne calyculata), and huckleberry {Gaylussacia dumosd). Sphagnum moss can form a contmuous and stable mat beneath the shrubs, or it can be localized on small hummocks at the base of the shrubs.
One association has been described in Massachusetts: the Vaccinium corymbosum-Rhododendron viscosum tall shrub bog and bog border association [TYPE A in Kearsley, 1999).
Moats of wet, ponded areas associated with highbush blueberry thickets can fimction as vernal pool habitat if water remains standing for 2-3 months; these areas provide important amphibian breeding habitat

Habitat values for Associated Fauna:
Small, shallow dq}ressions within iqsland forest that are temporarily flooded and provide important breeding habitat for amf^bians.
Woodland vernal pools are small, shallow depressions that are isolated from other surface waters. They flood in the spring and sometimes in the fall, but they are typically dry in the summer. They often have hydric soils. When dry, woodland vernal pools can often be recognized by a layer of stained leaves covering the dry depression.
Woodland vernal pools often have little or no vegetation, but they are ringed by upland trees or shrubs, such as sweet pepperbush (Clethra alnifolia). Other forested and non-forested wetland community types can function as vemal pool habitat if they have long periods of standing water, i.e. 2-3 months. See habitat values description under other community descriptions.
No associations have been described in Massachusetts.
Vemal pools are tracked as a separate community type because of the important habitat they provide for amphibians and invertebrates. Since vemal pools are temporary bodies of water, they do not support fish populations. Wood frogs (Rana sylvatica), Eastem spadefoot toads (Scaphiopus holbroofdi), and four local species of mole salamanders (Ambystoma spp.) have evolved breeding strategies intolerant of fish predation on their eggs and larvae; the lack of fish populations is essential to the breeding success of these ^)ecies. Other amphibian species use vemal pools but they do not depend on them, those species include American Toads (Bu/o americanus\ Green Frogs {Rana clanutans\ and Red-spotted Newts {Notophthalmus viridescens). Vemal pools also support a diverse invertebrate faima, including fairy sluimp (Eubranchipus spp.) which complete their entire life cycle in vemal pools.

Boxford State Forest and Wildlife Management Area have abundant vemal pools.
Woodland vernal pools are often overlooked during the dry season, so they end up being destroyed by filling or grading. They are often too small to meet minimum size requirements for state wetland protections. Hydrologic alterations also threaten vemal pool communities.
Inventory is needed to identify where woodland vemal pools are. Protection of suiroimding uplands is important for vemal [xx)! species.
1800 vemal pools are currently certified in the state.

Habitat Values for Associated Fauna:
A community dominated by invertebrates and non-vascular plants, in a high-stress environment alternately covered by tides and exposed to desiccation and thermal stress.
Along rocky shores, from the supratidal ^lash zone to the limits of light penetration in the subtidal zone.
The communities of rocky shores are dominated by crustaceans, mollusks, and macroscopic algae. The algae (seaweed) provide cover and food for the animals. The rocky shore commimity shows a distinct zonation from the splash zone to the zone of complete inundation.
This was probably the habitat of the extinct sea mink (Mustela vison macrodon). Wintering sea birds such as Northern Gannets (Moms bassanus) and Great Cormorants (Phalacrocomx carbd) feed among submerged rocks close to shore. Wintering Purple Sandpipers {Calidris maritima) forage among exposed rocks in low tide. The habitat includes tidal pools which support many marine invertebrates.

Environmental setting:
Marine intertidal areas protected from intense wave action, with relatively stable sediments, in various proportions of silt, clay, sand, and organic materials.
Found in protected, low-energy coastal sites, such as bays and coves behind headlands or barrier beaches, between low and high tidal limits. More protected than Marine intertidal gravel/sand beaches. Marine intertidal flats are sometimes bordered by salt marshes on the landward side and tidal channels or subtidal eelgrass beds on the seaward side. Tidal flats are physically and biologically linked to other coastal marine systems; organisms of tidal flats depend upon organic materials brought in from adjacent coastal, estuarine, riverine, and salt marsh habitats.
Vegetation Description: Includes some areas with eelgrass (Zostera marina), but other areas are sparsely vegetated.
Invertebrate species richness can be high. Mud areas tend to have a higher productivity than sand or gravel areas. Micro-algae are abundant

Concept: The vegetation surrounding and in coastal saline to brackish ponds with shallow water. The inland
ends tend to be fresher, with denser, taller vegetation developing.
Environmental setting: Salt ponds are found on the south and east sides of Cape Cod, Martha's Vineyard, Nantucket, and in
Buzzards Bay. The ponds are more or less isolated from the ocean by sand spits that cut off a bay. When closed, the ponds tend to be brackish and have little tidal action. The ^it may become broken by storms or human intervention and recluse by drifting sand. Water levels fluctuate wiien the ponds are closed to the ocean, with freshwater inflow from streams and rain maintaining the levels. Shorelines often support marsh areas that are similar to brackish salt marshes. Sea-level fens are very restricted areas within the marshes.
Vegetation Description: Eelgrass (Zostera marina) beds are often dominant communities of the subtidal areas. Other areas
may not be vegetated Towards the ocean, mud or sand shores appear during dry spells tliat support mud flat species such as mud wort (JJmosella australis\ dwarf spikerush {Eleocharis parvula\ seaside flatsedge {Cyperusfilicinus), seaside crowfoot (Ranunculus cymbalaria\ false pimpernel {Undemia dubia\ waterwort (Elatine minima) and shore pygmy-weed (Crassula aquatica). The vegetation of inland ends is similar to the landward, brackish, portions of other salt n^arshes, with beds of narrow-leaved cattail (Typha angustifolia), common reed {Phragmites australis\ freshwater cord-grass {Spartina pectinata), saltmarsh sv^itchgrass (Panicum virgatum var. spissum\ bulrushes {Scirpus spp. Particularly S. pungens), and mock bishop's-weed {Ptilimnium capillaceum).

Associations: Habitat values:
palustrine community associated with salt ponds.
Herbaceous/graminoid peatlands that occur at the upland edges of ocean tidal marshes. The combination of upland freshwater seepage and infrequent salt or brackish overwash produces a mixed plant community of freshwater and estuarine ^)ecies.
Sea-level fens occupy the interface between estuarine marshes aai upland seepage slopes, and therefore have a distinct species assemblage including both estuarine and palustrine species. There are two hydrologic influences: acidic freshwater seepage from the uplands and jseriodic salt or brackish overwash from the adjacent marsh. Both are needed to produce the combination of species observed in sea-level fens.
Probable community type in Massachusetts, but vegetation descriptions are lacking. There are two probable occurrences reported from Martha's Vineyard that have saltmarsh spike-sedge (Eleocharis rostellata) co-occurring with acidic fen species. Plot data are needed, Ludwig (1995) described the flora of sea-level fens from Virginia, Delaware, New York, and Connecticut. He described three diagnostic species: saltmarsh straw-sedge (Carex hormathodes), saltmarsh spike-sedge {Eleocharis rostellata), and saltmarsh-threesquare {Scirpus americanus). Other common species include: New York aster (Aster novi-belgii), twig-sedge (Cladium mariscoides\ spatulate-leaved sundew (Drosera intermedia), Canada rush (Juncus canadensis), pondshore-rush (Juncus pelocarpusX swamp-candles (Lysimachia terrestris), common reed (Phragmites australis\ white beak-sedge (Rhynchospora alba), swamp-rose (Rosa palustris), common threesquare (Scirpus pungens), poison ivy (Toxicodendron radicans), and marsh St. John's-wort (Triadenum virginicum). [State Historical, deceitful ^ike-sedge (Eleocharis fal lax) listed as common in more southern occurrences.]
No associations have been described in Massachusetts.

ESTUARINE INTERTIDAL: SALT MARSH
CE2B 100000
S3
No
Concept Environmental setting:
A graminoid dominated, tidally flooded coastal community with several zones.
Salt marshes form in areas subject to oceanic tides, but are somewhat sheltered from wave energy. They usually occur in estuaries and behind barrier beaches and spits. A peat develops in the higher marshes, with marsh plants extending into flats in stabilized areas, raising the surface area and allowing the marsh to expand. Upper edges may be brackisL
Vegetation Description: Saltwater cord-grass (Spartina altemijlora) dominates the low marsh area, between the low and
mean high tide. Between the mean high tide and the spring high tide, the high marsh area, salt- marsh hay {Spartina patens) dominates, usually mixed with spike grass {Distichlis spicata). Towards the upland edge, black grass (Juncus gerardii) becomes more common. Mixed throughout, e^jecially towards the upper edges sea - lavender {Limonium carolinianum\ seaside goldenrod (Solidago sempervirens\ and salt tolerant species. At the freshest edges, salt marsh switch grass {Paniciun virgatum) may be common. At those upper edges and on ditch spoils, groimdsel-tree (Baccharis halimifolia) and saltmarsh elder (Ivafrutescens) can form shrubby zones. Scattered in low, poorly drained, salty areas, salt pannes form, with ]X)pulations of glasswort (Salicomia spp.) and saltwort (Salsola kali).
Associations:
Habitat Values for Associated Fauna:
Low marsh, high marsh, salt shrub, and salt panne are often described as separate communities within the salt marsh system.
Many species of birds forage in salt marshes. A few such as Seaside Sparrow (Ammodramus maritimus) and the Saltmarsh Sharp-tailed Sparrow {A. caudacutus) nest there as well. In fall and winter. Short-eared Owls {AsioJlammeus\ Siowy O'wls (Nyctea scandiacaX and Northern Harrier (Circus cyaneus) hunt salt marshes. In summer. Snowy Egrets (Egretta thula) and Glossy Ibis {Plegadisfalcinellus) forage in pools at low tide. Few mammals are resident in salt marshes, but Meadow voles (Kiicrotus pensylvanica) use them, retreating to dryer areas during high tides. Fiddler crabs are invertebrates that are identified with salt marsh creelcs.

ESTUARBVE INTERTTOAL: BRACKISH TIDAL MARSH
CE2B300000
SI
Yes
Concept: Mixed herbaceous marsh that is flooded by daily tides, and occurs in brackish reach of coastal
rivers. May also occur in smaller patches in upper zones of coastal salt marshes and salt ponds, usually near seepages or freshwater transition areas.
Environmental setting: Brackish tidal marshes occur along free-flowing coastal rivers. Smaller patches often occur along
the edges of salt marsh habitat, near stream inputs, seepages or other freshwater transition areas. Tidal amplitude ranges from 0 to 150 cm [comparable to freshwater tidal marshes], while average armual salinity is [0.5] - 5-18 ppL The community is often structurally diverse, including high marsh and low marsh, with occasional occurrences along rocky shores, seepages, and ditches. Brackish Tidal Marsh, mud flat zone is rich in organic sediments and, grades into adjacent less organic Brackish Mud Flats which are classifled as Estuarine Intertidal: Saline/Brackish Flats.
Vegetation Description: Narrow-leaved cattail {Typha angustifoUd) is typically dominant in the backmarsh, with frequent
stands of common reed {Phragmites australis). Freshwater cord-grass {Spartina pectinata) and saltmarsh bub^ush (Scirpus robustus) occur along the banks, associated with saltmarsh sedge (Carex paleacea) and marsh bentgrass (Agrostis stolonifera\ which frequently sprawls over the edge. Low marsh supports stands of saltmarsh cord-grass {Spartina altemiflora) and threesquare (Scirpus pungens). Mudflats and shores support sparse low herbs such as water pimpernel {Samolus valerandi var. parviflorus \ mud lily {Lilaeopsis chinensis) and creeping spearwort {Ranunculus jlammula var. ovalis). Plants of freshwater tidal marshes occasionally occur in the higher zones of brackish marshes.

Massachusetts' brackish tidal marsh communities appear compatible with Connecticut's associations: (Spartina altemiflora - Lilaeopsis chinensis community, Typha angustifolia - Hibiscus moscheutos community, Spartina patens - Agrostis stolonifera community, Scirpus pungens - Sagittaria ^p. tall grassland).
This community provides outstanding general wildlife habitat, with abundant food sources for migratory and wintering waterfowl, and is generally associated with river reaches with spawning habitat for anadromous fisheries. Amphibian and reptile diversity is lower than in freshwater tidal communities.

Large examples are known from the North and South Rivers; also occurs on the Palmer, Wes^rt, Paskamansett, Weweantic, Agawam, Mashpee, and Merrimack Rivers, and probably along several other rivers on the north shore. Occurrences along salt marshes are not well documented.
Invasive species appear to be the primary \hreai to this natural community. Brackish tidal marshes in several rivers are dominated by common reed (Phragmites australis\ and purple loosestrife {Lythrum salicaria) appears to be more aggressive in brackish marshes than in freshwater tidal marshes.
Monitor invasive plant populations, and determine feasibility of control measures.

Yes
Concept: Mixed herbaceous marsh flooded by daily tides, and occuning in the freshwater reach of coastal
rivers.
Environmental setting: Freshwater tidal marshes occur along free-flowing coastal rivers. Tidal amplitude may range from 0
to 1 SO cm, and average annual salinity is less than O.S ppt. [from O.S ppt to 5 pp. salinity, there is a gradient of species to the more clearly brackish, which has an average annual salinity of 5-18 ppt]. This community occurs upstream of brackish tidal marsh, in the upper limits of tidal influence. The community may often be structurally diverse, including high marsl^ low marsh, mud flats, rocky shore, ditches and seepages.
Vegetation Description: Dominant species include: blue joint {Calamagrostis canadensis), sedges (Carex stricta\ narrow- leaved cattail (Typha angustifolia), wild rice (Zizania aquatica\ smartweeds & tearthumbs {Polygonum punctatum, P. ari/oliunt), jcwclwced {Impatiens capensis), climbing hempweed (Mikania scandens) and sweet flag (Aconis calamus). Shrubs such as buttonbush (Cephalanthus occidentalis) and silky dogwood (Contus amomum) may occasionally be present Inundated False Pimpernel {jjndemia dubia var. inundata), which occurs in this community, is globally ranked by The Nature Conservancy but not listed in Massachusetts.

Habitat Values for Associated Fauna:
Caldwell & Crow ( 1 992) describe eight cover types from a freshwater tidal area of the Merrimack River (\ ) Spartina altemiflora; (2) Sagittaria graminea; (3) Scirpus tabemaemontani: (A) Spartina pectinata; (5) Amaranthus cannabinus; (6) Scirpus ptmgens; (7)Acorus calamus; (8) Zizania aquatica. That study area did not have a well developed high marsh area. Three of the TWINSPAN types were on rocky substrate, but within the freshwater tidal influence: (4) Spartina pectinata: {S) Amaranthus cannabinus; and (6) Scirpus pungens.
This community provides outstanding general wildlife habitat, with abundant food sources for migratory and wintering waterfowl, and is generally associated with river reaches with spawning habitat for anadromous Gsheries. It tends to have more vertebrate species than do the Brackish Tidal Marshes, such as freshwater snakes and muskrats.

Best examples are along the North River , and the Merrimack River. Smaller examples on the South, Palmer, Masl^iee, Agawam and Paiker Rivers.
Invasive plants purple loosestrife (Lythmm salicaria) and yellow flag {Iris pseudacorus) are established in some systems, although long-term threat is unknown. Alteration of river hydrology from excessive water withdrawal may have significant effect on plant commxmities. Development associated with recreational activity {docks, landings) may threaten rare plants in tidal shone habitat In the past dams were often placed in rivers below the upper reaches of the tidal influence and so reduced the areas with tidal influence.
Monitor invasive plant populations. Determine hydrologic requirements, and develop system for monitoring hydrologic stress. Prevent alteration of tidal shores.

Habitat Values for Associated Fauna:
Dense to open shrubland flooded by daily tides, occurring along the freshwater to brackish reach of coastal rivers.
Normally located as a transition between freshwater tidal marsh and freshwater tidal swamp, there may also be patches of tidal shrublands throughout the freshwater tidal marshes. There is a great deal of micro-relief [tussocks and hollows] leading to high species diversity. Flood waters are typically slightly acid [pH less than 5] and soils are usxially mineral without significant peat deposits. Average aimual salinity values of less than 0.5 ppt would be e?q)ected in freshwater tidal shrublands, and (0.5) -S -18 {i^t in h^ckish tidal swamps.
Tidal freshwater, or slightly brackish shrublands dominated by sweet gale (Kfyrica gale) and smooth alder (Alnus semdata) with some speckled alder {Alnus incana ssp. rugosa). Some examples may have a mixed canopy with other shrubs such as silky dogwood (Comus amomum), swamp-rose {Rosa palustris), winteibeny (Jlex verticillata), common elderberry (Sambucus canadensis), willow (Salix spp.), buttonbush (Cephalanthus occidentalis\ tmd poison ivy {Toxicodendron radicans). More northern examples may contain arrow-wood {Viburnum dentatum var. lucidum) and meadowsweet {Spiraea alba var. latifolia). Tussock-sedge {Carex stricta) may also be present Some herbaceous associates are Royal fern {Osmunda regalis var. spectabilis\ marsh-fem {Thelypteris palustris var. pubescens), bedstraws {Galium ^p.X common cat-tail {Typha latifolia\ arrow-arum (Pe/randm virginica). New York aster {Aster novi-belgii\ false nettle {Boehmeria cylindrical, touch-me-not {Impatiens capensis), and swamp milkweed {Asclepias incamata).
Becaxise the size and structure of the shrubland present are more important to most animals that would use a such a habitat, than are the slight fluctuations in water levels on a daily basis the species present are often those of maritime and coastal shrublands. Coastal shrublands are particularly important to migrating flocks of song birds.

Concept: Low stature forested wetland located along coastal rivers, at the upper limit of tidal influence, and
flooded by daily tides. Dense shrub understory and unusually rich herbaceous layer.
Environmental setting: Tidal swamps occur along free-flowing coastal rivers, occurring upstream of freshwater tidal
marsh, within the upper limits of tidal influence. The commimity represents an ecotone from tidal marsh to more typical non-tidal forested wetlands. Another variation of this commimity occurs along smaller streams at the upper limit of tidal influence. Tidal amplitude may range from 0 to 40 cm or more (estimatedX and average annual salinity is less than 0.5 ppt. in freshwater areas, with gradients to 5 ppt. Brackish occurrences (average annual salinity (0.5) 5-18 ppL) are also believed to occur, although more study is required. The best known occurrence of the community occurs along the edge of a freshwater tidal marsh, at the transition to a large Atlantic >^te cedar swamp.
Vegetation Description: Swamp white oak {Quercus bicolor) and red maple {Acer rubrum) occur on elevated hummocks,
and form an open forest canopy. The shrub layer is often very dense, and typically includes arrowwood (Viburnum dentatum var. lucidum), winterberry holly {Ilex verticillata) and silky dogwood {Comus amomimt). Large mucicy hollows flooded by daily tides support a diverse assemblage of herbs and graminoids. Most of these are typical of the nearby freshwater tidal marsh habitat, and include jewel weed {Impatiens capensis\ sensitive fern {Onoclea sensibilis) and wild rice {Zizania aquatica). A similar association is dominated by more dense stands of Aflantic uiiite cedar {Chamaecyparis thyoidea).
