Résumé

In Pseudotsuga menziesii stands in the Pacific Northwest, bat activity was higher in old-growth forests than in mature or young tree stands. In the S Washington Cascades, old-growth stands had 2.65-5.67 × higher bat activity than younger stands. In the Oregon Coast Range, old-growth stands had 2.54-9.75 × higher bat activity. Feeding activity was low in all forest stands and activity by bats occurred during the first 15 min of the evening, indicating that bats use old-growth forests only for roosting. Reproductive females were not captured at sites >300 m elevation in the Washington Cascades, but were common at elevations >300 m in the Oregon Coast Range. Reductions in old-growth forests may have a more severe impact on populations of breeding bats in the Oregon Coast Range. -from Author
