Abstract

Aspen (Populus tremuloides) and biodiversity

Robert L. Beschta

Many years ago, as an undergraduate, I took a range course in which the concept of “increaser” and “decreaser” plants was presented. That is, on sites where significant herbivory by large mammals occurs, either from livestock or high densities of wild ungulates, plants that are more palatable or less tolerant of herbivory tend to decrease over time. Whereas other plants may increase if, for example, they are relatively unpalatable, have features that allow a plant to resist herbivory (e.g., thorns), or are simply capable of establishing, growing, and reproducing in the presence of significant herbivory.
