Northern Long-Eared Bat

The listing status of the northern long-eared bat (NLEB) under the Endangered Species Act (ESA) has been the subject of litigation since the U.S. Fish and Wildlife Service (Service) originally listed it as threatened in 2015. At that time, the Service also issued an ESA Section 4(d) rule that allowed incidental take resulting from development activities to occur within its range and habitat where white nose syndrome (WNS) was not present, so long as certain best management practices, such as time of year restrictions on tree removal, were followed. In 2021, the U.S. Court of Appeals for the D.C. Circuit found that the Service’s 2015 listing decision did not adequately explain why the bat was not listed as endangered, and failed to address how impacts, such as habitat modification allowed under the 4(d) rule, affected the NLEB. The court remanded the 2015 rule to the Service for further consideration, but allowed the threatened listing and 4(d) rule to stay in place while the Service reconsidered the listing status for the species.
