White birch is the earliest successional, most shade-intolerant species of the four species in our study; red oak and yellow birch have intermediate shade tolerance and are considered mid- to late-successional species; and red maple is fairly shade tolerant and is considered a subclimax species (Burns and Honkala 1990).
These may become the dominant tree species in subclimax old growth forests, and may persist on into the climax forests.
This model assumes continuous and reversible transitions along a single, monotonic gradient between an overgrazed subclimax and an undisturbed climax state of vegetation and assumes that grazing and interannual variation in rainfall cause vegetation to change in the same way.
