DescriptionThe effect of a fuels reduction treatment on small mammals was investigated in lodgepole pine (Pinus contorta) and mixed conifer stands by trapping and track surveys in northeastern Oregon. The number of red squirrel (Tamiasciurus hudsonicus) and snowshoe hare (Lepus americanus) tracks decreased in all lodgepole pine treatments after harvest. Only two snowshoe hare tracks were detected in harvested stands of mixed conifer, compared with 46 tracks in unharvested stands. In most treatments the number of red-backed voles (Clethrionomys gapperi) decreased and chipmunks (Tamius spp.) increased after harvesting.
