Abstract

In this study, the we Passively recorded 28 nights at each of three survey location within Trout Park. Analyzed recordings using 2 auto-classification software programs, Sonobat and Kaleidoscope. Kaleidoscope identified 7,570 files as bat passes. Sonobat identified 9,938 files as bat passes. Identified 4 bat species: Big Brown, Eastern Red, Hoary, and Silver-haired Bats. Kaleidoscope indicated the presence of the Tri-colored Bat in the spring and summer survey periods. Bat populations may be helped by: Increasing the vegetation near the I90 overpass to add more connectivity between the 2 forest patches; Reducing understory clutter from invasive shrubs in the more heavily wooded areas to increase the availability of foraging habitat; Increasing available roosting habitat by maintaining snags and/or erecting bat boxes.
