The U.S. Fish and Wildlife Service (Service) and the National Oceanic and Atmospheric Administration's National Marine Fisheries Service (NOAA Fisheries) announce revisions to regulations that administer portions of the Endangered Species Act (ESA).

Final Rules

On July 10, 2026, the Service and NOAA Fisheries jointly announced a final rule removing the regulatory definition of “harm.”

Rescinding the Definition of “Harm” Under the Endangered Species Act

News Release

On July 17, 2026, the Service announced two additional regulatory revisions. The Service is removing the future use of its “blanket rule” option under section 4(d) of the ESA. This change does not affect the protections for species currently listed as threatened species but ensures that species listed as threatened species in the future receive the protections tailored to the species' individual conservation needs. 

Additionally, the Service is revising regulations related to section 4(b)(2) of the ESA to provide criteria and clarify the processes by which the Service will implement the statutory requirements of designating critical habitat. These revisions describe when and how we determine whether the benefits of excluding an area outweigh the benefits of designating the area as critical habitat.
