Deciduous Forest Region
	True deciduous forest (unlike the more extensive boreal-deciduous transition) is restricted to southwestern Ontario, although it occupies much of the eastern United States. Beech and sugar maple dominate, but the forest contains many more tree species than the boreal forest. The deciduous forest has a characteristic and moderately well-developed understory and ground flora. These plants provide a variety of microhabitats, even in the winter.
	The moderate, evenly distributed rainfall maintains a generally high humidity in summer, and the forest floor is covered with leaf mould which supports a rich microflora and microfauna. In Canada, much of the area originally occupied by deciduous forest has been cultivated.
	Many arthropod taxa occur in the deciduous forest. They include scattered representatives of basically subtropical groups (especially beetles) that do not live elsewhere in Canada, as well as herbivores, (leaf-feeders, wood-borers, and some fungivores).
