Abstract

Female short-tailed weasels (Mustela erminea) used piles of logging residue more than expected and used areas without logging residue less than expected when they were in 3-year- old regenerating aspen (Populus tremuloides) cutblocks during summer and fall (P < 0.001). Female weasels may prefer piles of logging residue because they offer greater amounts of food, larger numbers of rest sites, and greater availability of travel corridors. Our data indicate that food abundance, specifically the southern red-backed vole (Clethrionomys gapperi), best explains the preferential use of logging residue piles by female weasels. Recommendations for the management of logging residue piles are discussed
