Fort Drum Military Reservation – Bat Survey and Radio Telemetry Study

Lewis and Jefferson Counties, NY

In March 2015, Copperhead Consulting was contracted by the United States Army to conduct a mist net and radio telemetry study designed to determine the presence and roosting preferences of bats on the Fort Drum Military Reservation. Survey efforts primarily focused on the federally-threatened northern long-eared bat (Myotis septentrionalis), the federally-endangered Indiana bat (Myotis sodalis), little brown bat (Myotis lucifugus), big brown bat (Eptesicus fuscus), and silver-haired bat (Lasionycteris noctivagans) roosting within and adjacent to the reservation boundaries. Over the course of the project, 20 bats were radio-tagged and with the assistance of Copperhead’s aerial telemetry capabilities every radio-tagged bat was located. One of the radio-tagged bats was located over 9 miles away from its previous roost, a distance over which this bat most likely would not have been found using traditional ground tracking methods. By the end of the project, Copperhead was able to locate 51 individual roosts, one of which was a maternity roost being used by more than 200 little brown bats.
