The Green Creek estuary has a small channel that is used by Myotis sp. One lactating female Myotis keenii was captured at Green Creek on July 8. There was feeding activity along the forest margins and marshes at high elevation. In this study we did not attempt to systematically compare bat activity with detectors in forests vs. clearcuts. Bats were also seen flying along trails in the forest, particularly on the section between Deer Drop and Cave 47H. One of the larger pits within the clearcut, Skypot Cave, is used by bats for feeding.
Bats do use caves under both old-growth and clearcuts as hibernacula and for swarming.
The presence of another hibernaculum is suspected in one of the large caves under the previously logged area. It is also possible that these were emergent bats and were close to an unknown entrance. We have also found evidence of cave use by bats on a subjacent ridge. Thanksgiving Cave, an eight kilometre long system, is located between 500-800m elevational range on a ridge, three kilometres southeast of the study area. At the main entrance, we netted for two hours on September 18 and caught two male Myotis keenii .
