"Clear-cut logging, which destroys habitat for some animals, offers good living conditions for Townsend's chipmunks. They find denning sites, cover, and food among the fallen, decaying logs and sprouting evergreens. In the 1830s, an explorer named Townsend collected a chipmunk he called a ""pretty little fellow."" Later it was given his name. Townsend's chipmunks favor fruits over seeds, though a variety of both are eaten, as are fungi, lichen, insects, and other invertebrates."
