The work on the distribution of the mosses in the province is an extension of an earlier publication (Ireland and Cain 1975) of a checklist of the mosses of Ontario that was started in 1971. In that publication the distribution of each species and variety was listed for each county and district in the province. The work stimulated collecting in counties and districts that were poorly sampled, and the knowledge of the moss flora increased at a rapid rate as a result. The map localities are based on herbarium specimens examined and verified by the senior author. The specimens are contained mainly in the Canadian Museum of Nature (CANM) and the University of Toronto (TRTC). Some specimens have been seen in other herbaria as well, including Queen’s University (QK), Harvard University (FH), University of Michigan (MICH), New York Botanical Garden (NY), and Smithsonian Institution (US). The label data for all distribution records are kept on file in the Canadian Museum of Nature in Ottawa. Information concerning any of these records may be obtained by contacting the Bryology Section, Canadian Museum of Nature, P.O. Box 3443, Station D, Ottawa, Ontario K1P 6P4, Canada. The nomenclature is essentially that of Ireland et al. (1987) with recent additions by Anderson et al. (1990) and Anderson (1990) for Sphagnum. PHYSIOGRAPHY AND GEOLOGY Ontario (Fig. 1) is an immense province, extending over 1,600 km from its southern tip at Point Pelee (41° 57’ N) to its northern limit on the Hudson Bay (56° 50’ N). It stretches almost as far east to west from the St. Lawrence River on the Quebec border (75° 20’ W) to the Lake of the Woods on the Manitoba border (95° 10’ W). The total land area is 1,072,713 sq. km. The basic structural feature underlying most of Ontario is the Canadian (Precambrian) Shield. That portion which lies within Ontario is only a small part of the total area of the shield occurring throughout Canada. The Precambrian rocks of the shield in Ontario are between 2.5 billion and 800 million years old, but in many areas younger sedimentary rocks have been deposited over them. The province is comprised of four physiographic regions (Bostock 1970): Hudson, James, Laurentian and St. Lawrence Lowlands. The Hudson Region includes the Hudson Bay Lowland, the large area around Hudson Bay in the extreme northern part of the province. It comprises one-quarter of the land surface of Ontario. The region is a low, swampy, marshy plain with a belt of raised beaches that border the bay. The area Slopes gently towards James and Hudson bays. Elevations reach 60-180 m above sea level. Paleozoic marine sedimentary rocks cover massive or stratified Precambrian rocks. The James Region, which lies immediately below the Hudson Region, is the largest of the four physiographic regions. It is comprised of uplands with broad rolling hills, sometimes rugged, that rise gently from the Hudson Bay Lowland to about 460 m in their higher parts near the southwest and southern borders. Most of the uplands are 270 to 370 m in elevation. Precambrian strata of mostly granitic rocks cover most of the region, but there are many areas of mainly volcanic, sedimentary and intrusive rocks occurring throughout. Numerous lakes of various sizes are scattered throughout the region. One of the largest lakes, Lake Nipigon, is situated in the southwestern part of the region just above the north shore of the northernmost of the Great Lakes, Lake Superior. Deep canyons cutting through diabase, e.g. Ouimet and Cavern Lake, occur in the region between lakes Nipigon and Superior. Also in this region are cuestas and ridges of sedimentary rock, some extending as promontories into Lake Superior. They rise in places to ca. 240 m above the lakes and adjacent valleys. In the southeastern part of the region above Lake Huron are hills of sedimentary rock that are mostly 240 to 300 m in elevation.

Map of Ontario showing physiographic features and regions. The Laurentian Region is a small area of hilly terrain in the southeastern part of the province that rises abruptly above the St. Lawrence Lowlands. The hills are formed of Precambrian metamorphic rocks with some volcanic, sedimentary and intrusive rocks. The St. Lawrence Lowlands Region, which is in the extreme southeastern part of the province, is dissected by the Laurentian Region in the upper part. It is comprised of a series of highlands that are separated by lowlands of Paleozoic marine sedimentary rocks. The region is bounded by the lower Great Lakes, Ontario, Erie and Huron. The Niagara Escarpment is the most important topographic feature of the region. The escarpment extends in a sinuous westerly and northwesterly course to the Bruce Peninsula and Manitoulin Island. It is a northeasterly facing cuesta of Silurian carbonates that attains an elevation of 200 m in the south, rising about 90 m above the surrounding terrain, to 520 m in the northwest, about 300 m above Lake Huron along the south shore of Georgian Bay. Numerous waterfalls occur along the escarpment, the most important of which is Niagara Falls. CLIMATE Ontario is in three climatic regions (Hare and Thomas 1979): the southeastern part (i.e., the area in the St. Lawrence Lowlands physiographic region) is in the Great Lakes-St. Lawrence Region; the northern part, which is the largest part, is in the Boreal Region; and a narrow band 15-30 km broad bordering the Hudson Bay is in the Arctic Region. The Great Lakes-St. Lawrence Region basically has a continental climate (i.e., warm summers and cold winters), although in the central and western parts the climate is noticeably modified by the Great Lakes. The summers are usually longer and warmer in this region than those in any other part of Canada. The mean daily temperature average during the warmest month (July) in the southern part of the region is 22° C, while it is 21° in the northern part. During the coldest month (January) the mean daily temperature average is -4° C in the south and -11° C in the north. The mean yearly temperature average in the south is 9.2° C and 6° C in the north. Precipitation is evenly distributed throughout the year in the Great Lakes-St. Lawrence Region. The total yearly precipitation average is 836 mm in the southern part and 851 mm in the northern part. The highest amount of precipitation is in the summer (84 mm in June in the south and 82 mm in August in the north), while the winter has the lowest amount (52 mm in February in the south and 57 mm in the same month in the north). In the summer most of the rainfall is attributable to showers and thunderstorms. Snow can generally be expected from November to March. The Great Lakes are responsible for an abundance of snow in well-marked "snow belts" in their lee through the lake effect. In the Georgian Bay region normal snowfall exceeds 250 cm a year. The Boreal Region has appreciable snow cover for more than half of the year. Winters are cold and summers are short, although they may be hot. The mean daily temperature average at different latitudes throughout the region during the warmest month (July) is 16° to 17° C, while it is -18 to -24° C in the coldest month (January). The mean yearly temperature average is 0.7 to 41° C. Precipitation in the Boreal Region is highest during the summer months, ranging from 67 to 99 mm, and lowest during the winter, ranging from 21 to 56 mm, depending on the locality. The total yearly precipitation average is 597 to 871 mm. The Arctic Region along the Hudson Bay has long and cold winters dominated by arctic airstreams. The mean yearly temperature average is ca. -5° C. Precipitation is light but evaporation rates are low. The total yearly precipitation average is 640 to 800 mm. VEGETATION Ontario has four regions (Fig. 2) of natural-vegetation (Rowe 1972): Deciduous (Carolinian) Forest, Great Lakes-St. Lawrence Forest, Boreal Forest, and Tundra. These four regions are characterized by their dominant trees and other plants, including the mosses. The regions are related to temperature as expressed in the length of the growing season and, therefore, their boundaries are not sharply delimited. A brief discussion primarily of the trees in the regions follows. For a more detailed list of the other vascular plants consult Falls and Soper (1964) and Scoggan (1966). The Deciduous (Carolinian) Forest Region contains many different species of deciduous trees, some of which are found nowhere else in Canada. The dominant trees are sugar maple (Acer saccharum Marsh.), red maple (Acer rubrum L.), beech (Fagus grandifolia Ehrh.), basswood (Tilia americana L.), white ash (Fraxinus americana L.), red oak (Quercus rubra L.), white oak (Quercus alba L.), black cherry (Prunus serotina Ehrh.), ironwood (Ostrya virginiana (Mill.) K. Koch), American elm (Ulmus americana L.), shagbark hickory (Carya ovata (Mill.) K. Koch), and butternut (Juglans cinerea L.). Typical southern deciduous trees, some reaching their northern limit in Ontario, are sassafras (Sassafras albidum (Nutt.) Nees), black walnut (Juglans nigra L.), wild crab- apple (Malus coronaria (L.) P.Mill.), flowering dogwood (Cornus florida L.), tulip-tree (Liriodendron tulipifera L.), pawpaw (Asimina triloba (L.) Dunal), sour gum (Nyssa sylvatica Marsh.), red mulberry (Morus rubra L.), and chestnut-oak (Quercus prinus L.). Some coniferous trees, such as white pine (Pinus strobus L.), eastern hemlock (Tsuga canadensis (L.) Carr.), eastern white cedar (Thuja occidentalis L.) and red cedar Juniperus virginiana L.), are scattered among the deciduous trees, while others, like black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch), are restricted to isolated bogs or cool wet woods. The Great Lakes-St. Lawrence Forest Region is a transition between boreal and deciduous forests. Deciduous trees that are common to the region include northern species, such as white birch (Betula papyrifera Marsh.), yellow birch (Betula alleghaniensis Britton), trembling aspen (Populus tremuloides Michx.), and balsam poplar (Populus balsamifera L.) as well as the other species common to the Deciduous Forest Region, namely sugar maple, red maple, beech, basswood, red oak, ironwood, and American elm. Other deciduous trees that are locally abundant are black ash (Fraxinus nigra Marsh.), bur oak (Quercus macrocarpa Michx.), large-toothed aspen (Populus grandidentata Michx.), and showy mountain-ash (Sorbus decora (Sarg.) C.K. Schneid.). Common conifers of the region are white pine, white spruce, balsam fir (Abies balsamea (L.) Mill.) and white cedar. Hemlock is common in the southern parts of the region, while red pine (Pinus resinosa Ait.), jack pine (Pinus banksiana Lamb.), black spruce and tamarack are locally abundant in some habitats. The Boreal Forest Region is the most extensive region in Ontario. It is predominately comprised of coniferous trees, mainly white spruce, black spruce, balsam fir, tamarack and jack pine. The deciduous trees are primarily white birch, trembling aspen and balsam poplar. In the northern part of the region, i.e., the Hudson Bay Lowlands, extensive areas are covered by black spruce muskeg and tamarack bogs. The Tundra Region is a treeless band, up to 30 km broad, of open peatland along the coast of Hudson Bay. Scattered individuals of dwarf spruce and tamarack occur inland. There is a heath-like cover, varying from an open to a dense mat of mosses and lichens with a low layer of woody plants and scattered herbaceous perennials. Woody plants include Labrador-tea (Ledum groenlandicum Oeder), dwarf Labrador-tea (Ledum decumbens (Ait.) Lodd.), mountain avens (Dryas integrifolia Vahl.), dwarf birch (Betula glandulosa Michx.), alpine bearberry (Arctostaphylos alpina (L.) Spreng.), crowberry (Empetrum nigrum L.), soapberry (Shepherdia canadensis (L.) Nutt.), Lapland rosebay (Rhododendron lapponicum (L.) Wahl.), ground juniper Juniperus communis L. var. depressa Pursh) and several species of willows (e.g., Salix arctica Pall., S. arctophila Cock. ex Heller, S. brachycarpa Nutt., S. planifolia Pursh, and S. reticulata L.). 74 En Tundra Region Boreal Forest Region - Forest and Barren 54 54 1e Boreal Forest [Ill Region - Predominantly Forest Great Lakes - St. : Lawrence Forest wd Region Il Deciduous (Carolinian) | iE Forest Region i) ) 50 ii a | orn 46 0 100 Oo ROC 90 86 82 78 Figure 2.

Table 1. Distributional types recognized in Ontario mosses. Ontario Distributional Type No. of Mosses = %ofTotalFlora Cini oo de # ©. ©: +.

Western 8 2 Uncertain (Insufficient Data) 68 14 ot a A portion of the taxa are left unclassified (Uncertain) because of insufficient collections, a result of either inadequate field work or their rarity, making it impossible to determine their distribution pattern. It was sometimes difficult to place a taxon into any of the five categories because of widely disjunct localities from their main center of distribution. We placed Calliergonella cuspidata and Cirriphyllum piliferum, for example, into the Southern distribution pattern because the majority of collections are from southern Ontario and we did not feel either species would likely be found to any great extent outside this region in spite of their few disjunct localities in northern and western Ontario. In other cases some taxa have been classified on the basis of only a few records because of their known distribution pattern in the rest of North America. Dicranella cerviculata, for example, recorded from only two Ontario localities, both below 48° N latitude, is classified as Northern since we believe it will eventually be found more frequently in the northern latitudes, based on its predominantly boreal distribution elsewhere in North America. It should be noted that two of the mosses are endemic to Ontario, namely Tortula cainii and Neomacounia nitida. Tortula cainii, which was first collected in 1941, to our knowledge was last collected in 1978, but Neomacounia nitida, which was last collected in 1864, has not been collected since and it is believed to be extirpated. A list of the species in each distributional type follows. WIDESPREAD (269 taxa-55 %) Widespread-Throughout (130 taxa- 48%) Amblystegium humile (P. Beauv.) Crundw. A. serpens (Hedw.) B.S.G.
