Iowa, caves, bats, hibernacula
Nineteen caves in the eastern Iowa counties of Dubuque, Jackson, and Jones were surveyed for bat usage during the winter of 1983-84. A total of 1548 hibernating bats of 4 species (Myotis lucifugus, Myotis keenii, Pipistrellus subflavus, and Eptesicus fuscus) were counted in 12 of the caves. Only the previously reported federally endangered Myotis sodalis was not found.
