Great Lakes - St. Lawrence Precambrian Region

Natural Region 19


The three sections that compose this region are covered with a mosaic of coniferous and deciduous forests that are aflame with colour each fall. The region is one of continuous transition, with many species reaching their northern or southern range limits here. Along its northern border, species common to the boreal forest - white spruce, black spruce, white birch, jack pine, balsam fir -make up a high percentage of total forest cover.

In the southern portion of the region, sugar maple, American beech, basswood, white elm, red maple and other species common to the pure deciduous forests predominate. Eastern hemlock, yellow birch, white pine and red pine are found throughout the region.

This is also a region of transition for wildlife, with many species reaching their northern or southern range limits here. Wildlife typical of the boreal forest, such as moose, lynx, snowshoe hare and timber wolf are widespread, but reach their southern limits here. Chipmunk, mourning dove, cardinal and wood thrush are just a sampling of widespread species from southern forests that reach their northern limits here. Range limits change quickly in this region, reflecting the habitat alterations that are continuously occurring because of the effects of humans or natural fluctuations in climate, with some expanding northward and others spreading to the south.

Many species have limited ranges or disjunct populations within this region - eastern hognose snake, black rat snake, eastern massasauga rattlesnake, eastern ribbon snake, southern flying squirrel, piping plover, the re-introduced wild turkey, and Blanding's turtle, among many others.
