Activity of bats in thinned, unthinned, and old-growth forests in the Oregon Coast Range

Creator:

Humes, Marcia Lynn

Abstract:

Ten species of bats occur in the Oregon Coast Range and are hypothesized to be associated with late-successional forests. The development of characteristics of late-successional forests in young forest stands can be accelerated through silvicultural practices such as thinning I examined the effects of thinning on the use of forests...
