Northern Long-Eared Bat (Myotis septentrionalis)
Service Protects Northern Long-eared Bat as Threatened Species under Endangered Species Act with Interim 4(d) Rule
The northern long-eared bat is one of the species of bats most impacted by the disease white-nose syndrome. Due to declines caused by white-nose syndrome as well as continued spread of the disease, the northern long-eared bat will now receive protection as a threatened species under the Endangered Species Act.
The Service proposed the northern long-eared bat as endangered in October 2013. During review of the threats, we determined the northern long-eared bat meets the Endangered Species Act’s definition of threatened. Under the Act, a threatened species is likely to become endangered in the foreseeable future, while an endangered species is currently in danger of becoming extinct.
The listing becomes effective on May 4, 2015, 30 days after publication of the final listing determination in the Federal Register.
Also effective May 4 is an interim 4(d) rule that provides flexibility to landowners, land managers, government agencies and others as they conduct activities in northern long-eared bat habitat. Given the significant number of comments received in response to the 4(d) rule as proposed on January 15, 2015, we also opened a 90-day comment and will accept further input on the interim rule through July 1, 2015.
