Mixed‐severity wildfire and salvage logging affect the populations of a forest‐dependent carnivoran and a competitor

摘要: Effects of historical fire suppression in forested ecosystems, combined with increasingly frequent and prolonged periods of drought due to a changing climate, are predicted to drive increases in the extent and intensity of wildfires in western North America and elsewhere. Understanding the effects of wildfires on forest‐dependent species and interactions among species is important for conservation and management decisions. We used data collected from a long‐term carnivore monitoring program in northern California and southern Oregon, USA to investigate the effects of three mixed‐severity wildfires and salvage logging on a population of fishers (Pekania pennanti), forest‐dependent carnivoran of conservation concern, and a co‐occurring population of gray foxes (Urocyon cinereoargenteus), a competitor of similar body size. We developed a spatial capture‐recapture population model to estimate the short‐term …
