This project is a comprehensive investigation of the foraging and roosting ecology and distribution of bats in the mid-Atlantic and Northeast following White-nose Syndrome with emphasis on the threatened Northern long-eared bat and the endangered Indiana bat. Work has expanding to encompass Coastal Plain bat ecology including migratory patterns of non-hibernating bats. Project cooperators include US Fish and Wildlife Service, National Park Service, Department of Defense, NASA, and numerous state agencies and NGOs throughout the region.
