The canopy or top layer of this habitat is dominated by sugar maple, American beech, yellow birch, and white birch. Beech was once more abundant but the beech bark canker disease has drastically reduced numbers of healthy trees in the Acadian Forest Region. The shrub layer includes striped maple (also known as moosewood), mountain maple and young saplings of sugar maple and beech. The herb layer includes purple trillium, mitrewort, rosy twisted-stalk, starflower, wild lily-of-the-valley, wood aster, bloodroot, Jack-in-the-pulpit, false Solomon’s seal, blue cohosh, red and white baneberries, wild sarsaparilla, Dutchman’s breeches,violets, bedstraw, wood sorrel, silvery spleenwort and other ferns.
Deciduous woodlands are home to a wide variety of animals, including deer mouse, chipmunk, red squirrel, white tailed deer and snowshoe hair. Bird species include warblers, ovenbird, rose-breasted grosbeak, red-eyed vireo, flycatchers, and yellow-bellied sapsuckers. Canopy-feeding insects are important in food webs, while toads, wood frogs, salamanders, and the Maritime garter snakes occur on the woodland floor.
