Northern Long-eared Bat

Final 4(d) Rule

Section 4(d) of the Endangered Species Act directs the Service to issue regulations deemed “necessary and advisable to provide for the conservation of threatened species.” It allows the Service to promulgate special rules for species listed as threatened (not endangered) that provide flexibility in implementing the ESA. We use 4(d) rules to target the take prohibitions to those that provide conservation benefits for the species. This targeted approach can reduce ESA conflicts by allowing some activities that do not harm the species to continue, while focusing our efforts on the threats that make a difference to the species’ recovery.

 

For the northern long-eared bat, the 4(d) rule tailors protections to areas affected by white-nose syndrome during the bat’s most sensitive life stages. The rule is designed to protect the bat while minimizing regulatory requirements for landowners, land managers, government agencies and others within the species’ range.
