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

We, the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS; collectively referred to as the "Services") rescind the regulatory definition of "harm" in our Endangered Species Act (ESA or the Act) regulations. This rescission removes the regulatory definition of "harm" from the Code of Federal Regulations (CFR) in Title 50 parts 17 and 222.
