Small Mammal Responses to Diameter-Cut Logging in an Idaho Douglas-fir Forest

摘要

Relative small mammal populations were estimated on logged and unlogged plots from 1975 (first-year prelogging) through 1979 (third-year postlogging) by using live-trapping and mark-recapture methods. Three species made up 93 percent of 698 individual animals caught; deer mice (Peromyscus maniculatus), yellow-pine chipmunks (Tamias amoenus), and Gapper's red-backed voles (Clethrionomys gapperi). Deer mice populations were similar on both logged and unlogged plots. Numbers of yellow-pine chipmunks increased on logged sites. Red-backed voles disappeared from the small mammal community after logging.
