Abstract

I used stepwise logistic regression to identify factors important for habitat use by Sierra Nevada mountain beaver (Aplodontia rufa californica). Elevation, stream gradient, and abundance of willow (Salix spp.), alder (Alnus spp.), and fir (Abies concolor and A. magnifica) had the strongest positive associations with habitat use. Mountain beaver probably did not respond to these factors directly, but rather to a cool thermal regime, adequate soil drainage, and abundant food supply. Comparison of current with historical beaver use indicated no marked change since 1935.
