A Big Brown bat is checked after being caught in the netting they have set up. The UM Appalachian Lab is studying a large bat hibernaculum discovered in the abandoned Indigo Tunnel. Each week they trap, examine and release bats entering or leaving the tunnel, and try to locate radio-tagged bats in the area. Two objectives: to monitor bats (some endangered species) for signs of white-nose syndrome, and to document the population in the tunnel, which has been designated for a bike trail extension. Bats could block those plans.
