Abstract:

Twelve species of bats occur in Douglas-fir forests of the Pacific Northwest, of which nine are known to roost in tree cavities, bark crevices, or foliage, and several are closely associated with old-growth forests. Thus bat populations may be detrimentally affected by forest management practices involving the removal of large, old trees and snags. We review the life history characteristics and habitat relations of bats in the Pacific Northwest and provide information useful in managing forests for the persistence of native bat populations.
