Conservation and management of eastern big-eared bats

Big-eared bats (genus Corynorhinus) in the eastern United States are often associated with hardwood forest habitats and are potentially at risk due to factors such as habitat loss, disturbance to hibernacula and maternity sites, contaminants, genetic isolation, and disease. As a result, big-eared bats in the eastern US are species of special conservation concern. The Virginia (C. townsendiivirginianus) and Ozark big-eared bats (C. t. ingens) are federally listed as endangered and Rafinesque’s big-eared bat (C. rafinesquii) was a candidate species until 1996 when the U.S. Fish and Wildlife Service discontinued this list. Although much has been learned through research on these species, biologists have expressed concern that more knowledge is needed before effective management of these species is possible.

To address this need, a symposium was held in Athens, Georgia, in March 2010 to discuss research findings and future directions in research and conservation. The proceedings have been published by the Forest Service as General Technical Report SRS-145 Conservation and Management of Eastern Big-eared Bats: A Symposium ( It includes seven invited presentations on general ecological topics, 15 contributed oral presentations and three poster presentations on more specific research results, and a panel discussion on future directions in research and management. The editors are Susan C. Loeb (USDA Forest Service), Michael J. Lacki (University of Kentucky), and Darren A. Miller (Weyerhaeuser Co.). Sponsors of the symposium were USDA Forest Service, Bat Conservation International, University of Georgia Warnell School of Forestry and Natural Resources, Offield Family Foundation, and NCASI.
