Abstract
During summers 2002 and 2003, I used mist nets, bat detectors, and radio-telemetry to investigate bat community structure, activity, and the day-roost selection of evening bats (Nycticeius humeralis) on mature longleaf and managed loblolly study sites in southwestern Georgia. The Seminole bat (Lasiurus seminolus), red bat (L. borealis), and evening bat were captured most frequently on each site. Bat activity was greater in mature pine than other habitats on the longleaf site, and activity was lesser in the hardwood habitat type on the managed site. Evening bats on the longleaf pine landscape selected roosts based on tree, plot, and landscape scale characteristics, while bats on the managed landscape selected roosts based on only the tree and plot characteristics. I hypothesized that the greater availability of roosting structures (abundant large trees and snags) on the longleaf site allowed evening bats to select roost sites that had more favorable landscape characteristics (i.e. closer to water and foraging sites).
