MISSION STATEMENT
This study is a working component of the Montana Natural
Heritage Program's (MTNHP) grasslands/shrublands ecological
classification project (GSCP) and The Nature Conservancy's
ecology program in the western United States. The Nature Conser-
vancy program provides key information on plant communities to be
used for conservation planning, management, research, and moni-
toring. Although grasslands and shrublands cover over 75% of the
Montana landscape, an exhaustive review of existing information
(MTNHP 1990) revealed them to be the least documented vegetation
types of the state. Therefore, the GSCP is designed to complete
the classification over the full range of ecological conditions
and to conduct regional correlations of existing classifications.
The information provided by the project will be the basis for
programs to model the effects of management, global changes, and
other variables on the vegetation types and diversity patterns,
and their implications for further management and conservation
planning. The project will continue to focus on strong collabor-
ative work with the various state and federal agencies (BLM,
USFS, BIA, DOD) and other institutions (e.g. Montana universi-
ties) in order to contribute to the development of a tightly
integrated state-wide classification system.
ABSTRACT
Interrelationships betv;een vegetation composition and envi-
ronment were studied using 125 vegetation plots sampled in a 12.5
million acre (50,000 km^) area of predominantly mixed-grass
prairie in northeastern Montana. Using a combination of two-way
indicator species analysis, detrended correspondence analysis,
and detrended canonical correspondence analysis (DCCA) , 24
community types were identified. The patterns in community
composition were strongly correlated with soil disturbance and
moisture gradients and these relationships are discussed. Keys
for each community type sampled (and 54 additional types docu-
mented in the literature) are provided.

INTRODUCTION
This study provides a classification of plant communities
(primarily grasslands and shrublands) throughout northeastern
Montana (Figure 1) . The study emphasized locating and describing
rare or previously undescribed communities and common communities
in good to excellent ecological condition. Such a classification
will be useful in identifying sensitive communities and natural
areas where management activities may need to be adjusted to
maintain habitat values. Additionally, the classification pro-
vides a reference system for baseline monitoring of environmental
impacts and vegetation recovery and provides an ecological basis
for categorizing environmental variation.
This study represents a step towards developing a comprehen-
sive classification of Montana plant communities that will pro-
vide land managers and scientists a state-wide perspective of
community variation (nation-wide when correlated with other state
classifications) . Such a perspective is invaluable towards
making sound management prescriptions and predictions, designing
and interpreting experiments, and identifying areas of critical
importance for conservation.
ACKNOWLEDGEMENTS
All financial and personnel support for this study were
provided by the Montana Natural Heritage Program and the Montana
State Library. Many resource managers, particularly USDI Bureau
of Land Management, USDA Soil Conservation Service, and USDI
Bureau of Indian Affairs personnel, provided assistance in
locating field sites.
The authors would particularly like to thank Peter Achuff,
Lisa Schassberger, David Center, Margaret Beer, and Cedron Jones
for their reviews and feedback during the development of this
classification. Robert Ament provided conscientious assistance
during field work. Appreciation is also extended to Dorinda
Monson and Brooke Wineteer who helped prepare and clean the
immense amount of data generated by this study.
PREVIOUS RESEARCH
Grasslands and shrublands cover over 75 percent of the
Montana landscape yet are the most poorly described vegetation
types of the state. Figure 1 highlights both the vast expanse of
Montana grasslands and the sparseness of available detailed com-
munity characterizations (particularly in northeastern Montana) .
To date, studies characterizing grassland and shrubland communi-
ties of Montana have been of limited geographical and ecological
scope. The most extensive existing studies include Mueggler and

Stewart's (1980) in western Montana, Jorgensen's (1979) and
Harvey's (1982) studies in east-central Montana, and Hansen and
Hoffman's (1985) work in southeastern Montana. A dissertation
describing grassland communities of south-central Montana has
recently been completed by Steve Harvey, Montana State Univer-
sity, Bozeman.
Grassland and shrubland classifications that are available
for the northeastern Montana study area include Branson et al.
(1970), Mackie (1970), and Dusek (1971) but all of these studies
cover relatively small geographic areas.
Relevant grassland/shrubland classifications from adjacent
states and provinces include: Whitman and Hanson (1939), Coup-
land (1950; 1951), Hansen et al. (1984), Hansen (1985), Girard et
al. (1989), and Jones (1989).
In contrast to grasslands and shrublands, the classification
of the forest types of Montana is largely complete. The upland
forest classification provided by Pfister et al. (1977) has been
refined and completed by the work of Cooper and Pfister (1981;
1985), Roberts et al. (1979), Roberts (1980), Hoffman and Hansen
(1981) , and Hansen and Hoffman (1985) . Classifications of Mon-
tana riparian sites (including forested, shrub dominated, and
herb dominated communities) are nearing completion (personal
communication, Paul Hansen, Montana Riparian Association, School
of Forestry, University of Montana, Missoula).
Prior to initiating field sampling, literature review and
data from previous research was used to develop a preliminary
classification of northeastern Montana's plant communities.
Forested communities in the study area have been largely
described by Roberts (1980) and Roberts et al. (1979) while
riparian community types have been defined by Hansen et al.
(1990) . Grasslands and shrublands were found to be the least
documented plant communities of the area and were thus the focus
of data collection in this study.
STUDY AREA
The study area (Figure 1) includes all lands north of the
Missouri River in Blaine, Phillips, Valley, Daniels, Roosevelt,
and Sheridan counties; Hill County east of the Milk River; and
Hill and Choteau Counties east of the Northeastern Montana
Glaciated Plains Ecoregion (as defined by Omernik and Gallant
(1987) ) .
Physiography
The study area encompasses approximately 12.5 rr.illion acres
and ranges in elevation from about 1900 feet on the Missouri
River at the North Dakota border to 6900 feet at the summit of
Mount Baldy in the Bear's Paw Mountains. Except for the Bear's
Paw and Little Rocky Mountains, the area lies entirely within the
Glaciated Missouri Plateau section of the Great Plains Physio-
graphic Province (see Fig. 6 in Montagne et al. 1982). The
southern boundary of this section is defined by the southern
limit of continental glaciation during the last ice age. For the
most part, these plains consist of relatively flat to gently
rolling sedimentary (particularly shale) and glacial till sur-
faces modified by stream erosion and past glaciation (Veseth and
Montagne 1980) . Some areas of sharply dissected badlands topog-
raphy do occur, particularly along the Missouri River.
The Bear's Paw and Little Rocky Mountains occur as isolated
"island" uplifts within the study area. A wide range of parent
materials occur within these mountain ranges although the central
portions of both ranges are predominantly igneous (Veseth and
Montagne 1980) .
Climate
Most of the study area experiences the extreme summer heat
and winter cold of a continental climate and lies directly in the
path of many arctic air masses from the north (Montagne et al.
1982). Average annual precipitation varies from over 30 inches
at the crest of the Bear's Paw Mountains to between 10 and 12
inches throughout the bulk of the study area (see sheet 2 in Ross
and Hunter 1976) . The average length of the freeze-free season
varies from less than 7 0 days at the crest of the Bear's Pav/
Mountains to greater than 130 days along portions of the Milk
River (see Fig. 13 in Montagne et al. 1982).
METHODS
Data Collection
To maximize the efficiency in sampling the range of vegeta-
tion and environmental variation, sample sites were selected
using a modification of the "gradsect" (gradient transect) method
described and evaluated by Gillison and Brewer (1985) and applied
by Austin and Heyligers (1989) . The method, as applied in the
present study, involved selecting a set of USGS 7.5' topographic
quadrangle maps containing the maximum perceived range of shrub-
land/grassland environmental variation in the overall study area.
Emphasis was placed on representing the range of moisture,
temperature, radiation, and soil nutrient regimes since these
factors likely have a primary influence on species occurrence and
growth .
The following site attribute information was overlaid onto a
USGS quadrangle index map of the study area to select quadrangles
for sampling among the approximately 470 available:
a) land use (from Fig. 23 of Montagne et al. 1982) -
quadrangles falling predominately (i.e., over 50%)
in agricultural land uses were excluded from fur-
ther consideration
b) average annual precipitation (from Sheet 2 of Ross
and Hunter 1976) - three classes were subjectively
defined, i.e., <12 inches, 12 - 16 inches, >16
inches. This attribute was regarded as an indica-
tor of moisture regime.
c) average length of freeze-free season (from Fig. 13
of Montagne et al . 1982) - three classes were
subjectively defined, i.e., <100 days, 100 - 120
days, and >120 days. This attribute was regarded
as a indicator of temperature regime.
d) surficial geology (from Figs. 9, 13, 17, 21, 23,
25, and 32 of Veseth and Montagne 1980) - the six
classes represented by the Veseth and Montagne
figures were used (Figs. 21 and 23 were subjec-
tively merged) . This attribute was regarded as a
indicator of nutrient regime.
e) Radiation regime was not considered in this
process since it varies greatly at relatively fine
geographic scales for different slopes and
aspects, particularly in complex terrain. Plot
selection in the field attempted to include a wide
range of slope/aspect combinations in each samp-
ling area.
A total of 175 plots v;ere targeted for sampling based on the
time available for this study (note: only 125 plots were ulti-
mately sampled) . A total of 5 plots/selected quadrangle were
chosen as a reasonable average to represent local-scale patterns
in community composition. Thus, 35 quadrangle maps were selected
for sampling (i.e., 5 x 35 = 175).
After eliminating agriculturally dominated quadrangles from
the pool (this reduced the number of quadrangles from about 470
to 221) , a matrix of precipitation/freeze-free classes was
constructed and the number of quadrangles in each class was
recorded. The percentage in each class relative to the total
number of quadrangles (221) v;as used to determine the number of
quadrangles (by class) to be included in the pool to be sampled
(e.g., 25% in class Z x 35 sample quadrangles = 9 plots of class
Z in the sample pool) .
An attempt was made to maximize surficial geology variation
within the sample pool by including as many geologic classes as
possible within each of the above sample classes. Also, sample
quadrangle selection was biased towards quadrangles that included
the greatest number of geologic classes within a precipitation/
freeze-free class. Additionally, an attempt was made to maximize
the geographic dispersion of quadrangles selected while main-
taining the primary objective of maximizing environmental varia-
tion.
Finally, in cases of an equal choice between selecting a
quadrangle encompassing primarily private land versus one encom-
passing primarily public land, the public land quadrangle was
selected. This was done to enhance the ease of land access.
To minimize the confounding nature of heavy disturbance on
vegetation occurrence, areas severely overgrazed, herbicide
treated, mechanically disturbed, artificially seeded, or irri-
gated were not sampled. Plots were established within portions
of stands that appeared to be relatively uniform in topography
and vegetation structure. Within an area, one to five plots were
chosen from different topographic positions and where judgement
indicated a marked change in vegetation composition.
Plot selection focused on contemporary stands of vegetation
without reference to successional relationships among stands. No
attempt was made to solely sample remnants of presettlement vege-
tation.
The data were recorded on a Natural Heritage Program Commun-
ity Survey Form for each plot. These forms are basically the
same as the general plot data and ocular plant species data forms
used by the USDA Forest Service (USDA 1987) . Complete lists and
canopy cover estimates of vascular plant species were recorded
within each 375 m^ circular study plot. Site information such as
altitude, slope, aspect, parent material, landform, and erosion
type were also recorded for each plot (Table 1) . Soil taxon was
recorded when a survey report was available for the site.
Data Analysis
Analysis focused on using a combination of classification,
to determine community types, and ordination (gradient analyses),
to describe general patterns of communities in relation to envi-
ronmental factors. Classification was accomplished using two-way
indicator species analysis (TWINSPAN; Hill 1979a) in the CEP MS-
DOS computer package (Mohler 1937) . Ordination was achieved
using the detrended correspondence analysis (DCA) and detrended
canonical correspondence analysis (DCCA) algorithms in the CANOCO
computer package (Ter Braak 1988) . The input data were species
cover variables recorded in each plot and, in the case of DCCA,

the 18 environmental variables recorded (Table 1; note -
radiation index was used in these analyses rather than aspect) .
Both TWINSPAN and DCA are based on the same mathematical strategy
(i.e., reciprocal averaging; Hill 1979a, b) and thus offer direct
comparisons between the results of ordination and classification.
All default options in the TWINSPAN algorithm v;ere used
except that pseudospecies cut levels were set at 0 , 2, 5, 20, and
50 percent cover. Also, all default options were used in running
the ordinations except that rare species were downv;eighted.
First, the entire data matrix of 125 stands and 230 species was
analyzed. To reduce the amount of variation being considered,
which is substantial in the v.'hole matrix, the data set was also
subdivided into forest, shrubland, and grassland groups which
were analyzed separately.
In some instances, a particular TWINSPAN class included a
plot or plots that, based on field experience and ordination
patterns, appeared to be better placed in a different existing
TWINSPAN class. These plots were repositioned in the classifica-
tion as appropriate.
In addition to helping refine the classification, the ordi-
nations assisted in describing and interpreting general patterns
of vegetation communities and environment. For example, DCA
extracts the dominant compositional gradients from the species
data matrix, irrespective of site variables, whereas DCCA
extracts the dominant gradients given the constraint that they
must be orthogonal linear comibinations of the supplied environ-
mental variables (Ter Braak 1988) .
Finally, species richness and diversity measures (Hill 1973)
were calculated for each plot using the AID computer program
(Overton et al. 1987). For those communities represented by more
than one plot, means and standard errors of means for each
measure were also calculated.
Taxonomic Considerations
Nomenclature follows Kartesz and Kartesz (1985) . Scientific
names of all species in this study, their code names, and their
synonyms (from GPFA 1986) are listed in Appendix A.
Stipa spartea was observed on two of the study's 125 plots
and was a dominant element at both of these sites. However,
close examination of initial TWINSPAN and DCA patterns suggested
close ecological similarity between S. spartea and S. comata
within the study area. Because of this similarity, the two
species v;ere grouped under S. comata for all analyses reported
here.

these patterns using DCCA (Appendix Figure HI) demonstrates that
conditions relating to soil disturbance and slope instability
(e.g., "badlands" and "blov;out" sites) are primary gradients
affecting compositional patterns among all plots.
Forest Plots
The four forest communities segregate distinctly within the
DCA ordination (Figure 3c) . The first two axes appear to reflect
complex moisture/landf orm gradients (Appendix Figure H2).
PINPON/JUNSCO occurs on relatively xeric sites on sedimentary
soils (mostly in breaks) and PINPON/PSESPI and PSEMEN/SCHSCO
occupy more mesic sites at higher elevations in mountains.
JUNSCO/ORYMIC was found in a moderately mesic draw v/ithin sedi-
mentary breaks.
Shrubland Plots
DCA ordination of all 53 shrubland plots indicates that 38
of the plots lie near the origin of axes 1 and 2 and that the
ARTLON/ORYHYM and SARVER/ATRGAR "badlands" types and the JUNHOR/
SCHSCO "blowout" type are outliers (Figure 3d) . This is the same
situation as described above for the first three axes of the DCA
ordination of all 125 study plots. When axes 1 and 3 are shown
(Figure 3e) the ARTTRI/FESCTUI type characteristic of the highest
elevations of shrubland occurrence in the study area appears as
an outlier (on the third axis) .
Removing all "badlands" and related communities (i.e.,
JUNHOR/SCHSCO, ATRCON-ARTTRI , SARVER/PASSMI , SARVER-ATRGAR, and
ARTLON/ORYHYM) and the ARTTRI/FESCAM high elevation type produces
the DCA ordination shov;n in Figure 3f. Plots within the
remaining seven communities group together, for the most part,
within the ordination space defined by axes 1 and 2.
DCCA interpretation of the overall patterns of vegetation
and environment within the shrublands is presented in Appendix
Figure H3 . Axis 1 is strongly correlated to soil disturbance and
slope instability with "badlands" communities having positive
scores and communities typically on relatively stable surfaces
with little erosion having negative scores. Axis 2 is charac-
terized by a complex radiation/moisture/disturbance gradient with
communities on sunny, xeric sites having higher scores than rela-
tively shady, mesic sites. Also, the JUNHOR/SCHSCO "blowout"
type has a low score on DCCA axis 2.
Grassland Plots
DCA ordination of all 56 grassland plots is presented in
Figure 3g (axis 1 vs. axis 2) . Most of the plots cluster near
the origin. The SCHSCO-I-IUHCUS and CALLON-CARINO community types
are outliers along the first axis. Both of these types are
24
characteristic of unstable "badlands" or "blowout" sites with
much bare soil exposed. Removing these two communities results
in the DCA ordination shown in Figure 3h (axis 1 vs. axis 2) .
The remaining five communities segregate within this ordination
space. Most of the separation occurs along the first axis.
DCCA ordination of all 56 plots is presented in Appendix
Figure H4 . The first axis represents a complex disturbance/
radiation/moisture gradient. Communities characterized by
unstable soils, often high radiation indices, and xeric condi-
tions have negative scores. In contrast, communities on rela-
tively stable soils, on low radiation index and relatively mesic
sites have positive scores.
Much less separation occurs along the second DCCA axis.
This axis is interpretable as a moisture gradient with more mesic
sites having higher scores than xeric sites (e.g., PASSMI-STIVIR
> PASSMI-BOUGRA > STICOM-BOUGRA) .
CONCLUSIONS
One function of the MTNHP is the development of a statewide
database of plant community occurrences. A major limitation is
the current lack of a comprehensive grassland/shrubland community
classification. This study represents a step towards achieving
such a comprehensive classification.
Another function of the MTNHP is to provide information
regarding communities and sites for conservation. A classifica-
tion such as this is necessary to define and identify key ele-
ments and sites in northeastern Montana for potential long-term
preservation. Similarly, government agencies could use the
classification for the identification and design of natural
areas .
This classification can be usefully applied in stratifying
vegetation/environmental variation to assess management options
and results. The classification can also assist in minimizing
impacts from intensive management by identifying sensitive plant
communities (e.g., PSEMEN/SCHSCO) . The classification also pro-
vides a tool for baseline monitoring and predicting long-term
vegetation responses to management activities. This capability
would also assist agencies in meeting regulatory mandates (e.g.,
requirements of FLPMA) .
Even following this study, existing classifications and data
inadequately describe the grassland and shrubland communities of
Montana. Major additional field sampling is necessary before a
comprehensive grassland/shrubland community classification can be
developed. This study in eastern Montana will continue over the
next two years. This effort will provide additional knov/ledge
25
regarding cominunity patterns, processes, and physical environment
relations. Such knowledge will be invaluable towards developing
full capability to inventory eastern Montana communities and to
increase predictive capability (e.g., build vegetation and
biodiversity models) .

Table B2 . --Key to northeastern Montana plant communities.
The following canopy coverage terms are used in the keys:
(1) "scarce" = less than 1% cover, versus "common" = greater than
1% cover;
(2) "poorly represented" = less than 5% cover, versus "well
represented" = greater than 5% cover; and
(3) "abundant" = greater than 25% cover.
When applying the key in the field the above definitions may need
to be adjusted to the next lower coverage class in cases where
species cover is thought to be unusually low (e.g., due to dense
shading, heavy litter accumulation, heavy grazing) .

APPENDIX C
Average Cover and Constancy for Community Types
Occurrences of each species in each community type are
indicated by tv.'o values. The first value indicates the mean
cover (in percent) for plots in which the species was present.
The second value is the percentage of the total number of plots
(in the community type) in v;hich the species was found.
In these tables, type number codes are defined as follows:

APPENDIX E
SITE CHARACTERISTICS FOR EACH PLOT
Both quantitative and categorical site characteristics are
presented. "RI" values are solar radiation indices at each plot
as determined using Frank and Lee (1966) . These indices equal
the ratio of the total annual potential isolation to the maximum
potential at the site. RI=.43 for all flat surfaces in the study
area. The code letters under "% Cover" are defined as follows:
S = bare soil G = gravel
L = litter W = wood
BV = basal vegetation
R = rock
M = moss
Classes of categorical site characteristics are defined as
follows:
Parent Material
Landf orms
alluvium
eolian
glacial till
sedimentary
igneous
mountains
rolling uplands
breaklands

APPENDIX F
SPECIES RICHNESS AND DIVERSITY MEASURES FOR EACH PLOT
The measures presented here are as described in Hill (1973)
and are all in units of number of species:
N(0) = the number of all species on the plot (e.g., =
species richness)
N(l) = the number of abundant species on the plot (e.g., =
base of the natural logarithms to the power of the
Shannon Index)
N(2) = the number of very abundant species on the plot
(e.g., = reciprocal of the Simpson Index)
For those communities represented by more than one plot,
means and standard errors (SE) of means for each measure are also
provided.

APPENDIX G
EXAMPLE COMMUNITY TYPE DESCRIPTION
Descriptions of the format presented in the following
example are currently being completed by the Montana Natural
Heritage Program for all community types (approx. 300) of
Montana.
138
Appendix G. — (continued)
Stipa comata-Bouteloua gracilis (STICOM-BOUGRA)
This community is very widespread in Montana and has been
recorded in all portions of the state except in the northwest.
Vegetation. — Stipa comata or S. spartea dominate this community.
Cover of these species is generally abundant. Other
characteristic graminoids include Bouteloua gracilis (well
represented) , Carex filifolia and/or C. eleocharis (common to
well represented) , and Koeleria macrantha (well represented) . If
Pascopyrum smithii is present its cover does not exceed 1%
(except in the Pascopyrum smithii phase described by Mueggler and
Stewart (1980)). Selaginella densa is often abundant in
northcentral and northeastern Montana and generally suggests
heavy grazing disturbance in such situations. Artemisia frigida.
Heterotheca villosa. Phlox hoodii. and Sphaeralcea coccinea are
typically present.
Physical Setting. — This community type is characteristically
found on gentle to moderate slopes of any aspect on rolling
uplands, broad alluvial benches and fans, and valley floors.
Elevations range from 2000 to 6000 feet and annual precipitation
varies from 8 to 14 inches. The soil surface is often covered by
a dense mat of Selaginella densa (northeastern/northcentral
Montana) or in some cases may feature abundant bare soil
exposures. Typical soil subgroups include Typic Ustorthents,
Ustic Torriorthents, Borollic Calciorthids, Aridic Argiborolls,
and Typic Argiborolls.
Adjacent Community Types. — This community generally occupies the
driest grassland sites in Montana. The Pseudoroegneria spicata-
Bouteloua gracilis or Pascopyrum smithii-Bouteloua gracilis (or
Stipa viridula) types occur on more mesic sites. The Pascopyrum
types are often found in clay-rich depressions within a matrix of
STICOM-BOUGRA. More mesic adjacent shrublands include Artemisia
cana-Stipa comata on generally even or convex slopes and
Symphoricarpos occidentalis or Prunus virginiana communities in
convavities.
Comments. — This community type has previously been described in
Montana by Mueggler and Stewart (1980) and in Wyoming by Ter-
williger et al. (1979). Additionally, Coupland (1961) describes
a Stipa-Bouteloua type in southern Saskatchewan and Alberta that
appears similar in composition to STICOM-BOUGRA. The type also
appears to be closely-related (perhaps ecologically equivalent)
to the Stipa comata-Carex filifolia type of Hansen (1985) .
Bouteloua gracilis is considered an increaser with heavy
grazing in this community type while Stipa comata generally
decreases (Mueggler and Stewart 1980) .

DETRENDED CANONOCAL CORRESPONDENCE ANALYSIS DIAGRAMS
Plot scores (•) for first and second axes of DCCA ordina-
tions of all 125 plots, 16 forest plots, 53 shrubland plots, and
55 grassland plots. The first axis is the horizontal axis and
the second axis is the vertical axis. Numbers in diagrams indi-
cate multiple plots at that ordination position. Centroids of
categorical environmental variables are indicated by "x". Vec-
tors indicate the direction of maximum change for a quantitative
environmental variable and the length indicates the strength of
their correlation with the ordination axes. Only the ten envi-
ronmental variables (of the 4 6 available) having the strongest
correlation with the axes are shown. See Table 1 for a list and
abbreviations of the environmental variables.
