Endangered and Threatened Wildlife and Plants; Interagency Cooperation Regulations

Document 2025-20551 is a Proposed Rule published by the Department of Interior in the Federal Register on November 21, 2025. We, the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS; collectively, the "Services") propose to revise portions of our regulations for section 7 of the Endangered Species Act of 1973, as amended (ESA or Act). The proposed revisions to the interagency cooperation regulations confirm the Services' application of statutory requirements for interagency cooperation, while continuing to provide for the conservation of listed species.
