Effects of new forest management strategies on squirrel populations.

Abstract

Two strategies for managing forests for multiple values have achieved prominence in debates in the Pacific Northwest: (1) legacy retention with passive management and long rotations, and (2) intensive management for timber with commercial thinnings and long rotations. Northern flying squirrels (Glaucomys sabrinus), Townsend's chipmunks (Tamias townsendii), and Douglas' squirrels (Tamiasciurus douglasii) were studied retrospectively in Douglas-fir (Pseudotsuga menziesii) forests managed under the alternative strategies in the Puget Trough of Washington. Flying squirrels were twice as abundant under legacy retention as under intensive management for timber, almost as abundant as in old-growth western hemlock (Tsuga heterophylla) forests on the Olympic Peninsula of Washington, but
