U.S. Fish and Wildlife Service Determines Critical Habitat is Not Prudent for Threatened Northern Long-eared Bat

 

Determination based on desire to reduce potential disturbance at hibernation sites, habitat requirements of species, and acknowledgement of white-nose syndrome as primary threat

Given the nature of the primary threats facing the species and the potential harm of publishing its hibernation locations, the U.S. Fish and Wildlife Service has determined that designating critical habitat for the northern long-eared bat under the Endangered Species Act (ESA) is not prudent. The Service’s determination does not affect the bat’s threatened status, which it received in 2015 due to white-nose syndrome, a deadly fungal disease impacting cave-dwelling bats.

 

Critical habitat is a designation under the ESA for lands that contain habitat features that are essential for the survival and recovery of a listed species, which may require special management considerations or protections. The ESA requires the Service to consider which areas are needed for a species’ recovery and to designate critical habitat accordingly, unless it determines that doing so is not prudent for the species.

 

In making its determination, the Service conducted an in-depth analysis of the bat’s seasonal habitat needs, which include mines and caves for hibernation in winter and forested areas for roosting and raising young in summer. Because designating critical habitat requires identification of specific tracts of land, the Service determined it is not prudent to designate hibernation sites as critical habitat. Doing so would increase the risk of vandalism and disturbance to bats at hibernation sites and could hasten the spread of white-nose syndrome.
