Endangered and Threatened Wildlife and Plants; Regulations for Listing Species and Designating Critical Habitat

Résumé

We, the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS) (collectively referred to as the "Services" or "we"), revise portions of our regulations that implement section 4 of the Endangered Species Act of 1973, as amended (Act). The revisions to the regulations clarify, interpret, and implement portions of the Act concerning the procedures and criteria used for listing or removing species from the Lists of Endangered and Threatened Wildlife and Plants and designating critical habitat.
