The impact of shelterwood and patch cuts harvests on bat communities was tested at three sites in Eastern Kentucky. Shelterwood harvests had 50% of the basal area and understory removed to create a uniform spacing of residual trees. Patch cuts had 1-hectare circular openings created to remove 50% of the basal area creating an aggregated spacing of residual trees. Acoustic detectors were deployed to assess activity levels pre-harvest. Sites were then sampled from 1 – 2 years post-harvest to determine differences. Pre-harvest data revealed little acoustic activity for the Myotis spp. at two sites. The remaining site had high activity of Myotis pre-harvest. All sites saw a large increase in bat activity post-harvest. Activity of low-frequency and mid-frequency bats increased in response to the harvests. Big brown and red bats were commonly captured within forest harvests. Tri-colored bats also captured, suggesting forest harvests could improve habitat. Myotis activity did not increase post-harvest at the site with a known population. Netting efforts revealed a remnant population of northern long-eared bats (Myotis septentrionalis). These bats were radio-tagged and tracked to day-roosts. All day roosts were in upslope habitats within 100 m of forest roads created for maintenance and logging operations.
