For the third year in a row the Forestry Crew has performed service with the North Carolina Wildlife Resources Commission to aid in their efforts to understand White-Nose Syndrome. This is an introduced fungal disease that has decimated bat populations in the eastern part of the United States over the last several years.

Bat with White-Nose Syndrome |
The Forestry Crew drives on a route through the Craggy Mountains on the Blue Ridge Parkway recording bat calls twice each summer. Each species of bat has a specific call signature. By recording the calls wildlife biologists can know how many bats of each species are located along the route. By recording calls before White-Nose Syndrome came to the North Carolina mountains, a baseline was established. As the disease affects populations along the route recordings of these calls allow an understanding for which species are being affected, and to what extent.
