The New Hampshire Fish and Game Department (NHFG), Nongame and Endangered Wildlife Program, is soliciting proposals from qualified parties to conduct bat acoustic and capture surveys at talus slopes and rock face habitats throughout New Hampshire. The objective is to investigate whether bats use talus slopes and rock faces for winter hibernation in New Hampshire and the importance of these nontraditional hibernacula to Myotis bats. Work includes implementation of an acoustic survey protocol using acoustic recorders, and where feasible bats will be captured for both identification and potentially tracking to learn more about their winter habitat use. The project will inform habitat conservation for priority bat species in New Hampshire.
