CWD Removal Effects on the Big-eared Woodrat in a California Oak Woodland
Two Key Findings:
(1) Coarse Woody Debris (CWD) is an important contributor to woodrat habitat quality, as it positively influenced both survival and reproduction.
(2) CWD promoted higher site fidelity, and therefore a safer environment, among resident woodrats.
Collectively, these findings have important population-level implications for big-eared woodrats, a keystone species on our study area. They may have particular significance given that California oak woodlands are currently faced with rapid and widespread environmental change.
