Willow and Aspen in the Ecology of Beaver on Sagehen Creek, California

Abstract

Like many other mammals, beavers thrive in sub-climax vegetation. Specifically, they often flourish where fire has been followed by appearance of Quaking Aspen, Populus tremuloides. This tree is the one most commonly felled for food and building material by beaver and its distribution is remarkably similar to that of the beaver.
