Canadian Range

The Canadian range extends from just west of Toronto through London to Windsor and south, through much of the Carolinian Zone (=Deciduous Forest Region) of Ontario (Figure 2). Although this species is no longer dominant in its forest habitat, remnant stump sprouts or occasional trees are found through much of its historical range.
