This week, the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS) (collectively, the Services) proposed revisions to the Endangered Species Act (ESA) regulations that, if finalized, will generally restore the regulations adopted in 2019, during President Trump’s first term.
