The WVDNR monitors bat populations by conducting surveys of hibernacula, Virginia big-eared bats maternity colony counts, and acoustic routes statewide. These surveys help document the spread of WNS and its impact on bat populations in West Virginia. In addition, the WVDNR coordinates winter cave entrance surveys to document unusual bat behavior that may be a sign of WNS and compiles reports of unusual bat behavior received from the public. WVDNR biologists collect samples for and assist in the field with WNS research projects being conducted by various laboratories, colleges, and universities. WVDNR personnel participate in national working groups addressing WNS issues.
