Range-wide Indiana Bat and Northern Long-eared Bat Survey Guidelines

The Indiana bat (Myotis sodalis) was originally listed as endangered under the Endangered Species Preservation Act of 1966 (32 FR 4001, March 11, 1967), and continues to be listed as endangered under the Endangered Species Act (ESA) of 1973, as amended. In 2015, the U.S. Fish and Wildlife Service (Service) listed the northern long-eared bat (Myotis septentrionalis) as threatened under the ESA and in 2022 the Service reclassified the northern long-eared bat as an endangered species. This survey protocol provides the Service's recommended guidance on survey methods and outlines additional reporting requirements for surveyors for Indiana bat and northern long-eared bat.
