Agencies Propose Definition of "Habitat" Related to Endangered and Threatened Species
The U.S. Fish and Wildlife Service and the National Marine Fisheries Service are proposing to add a definition of “habitat” to the regulations that implement section 4 of the Endangered Species Act (ESA). The proposed definition – which would be used in the context of making critical habitat designations – comes following a recent U.S. Supreme Court decision that concluded “critical habitat” must first be habitat (Weyerhaeuser Co. v. U.S. FWS, 139 S. Ct. 361 (2018)) (see AGC article). The Act prohibits adverse modification to “critical habitat” of listed species but it currently does not define “habitat.” A definition of habitat may help developers and contractors identify and avoid those areas, which would better inform ESA consultations during the planning and permitting process for projects.
