On June 24, 2022, the U.S. Fish and Wildlife Service (“FWS”) and the National Marine Fisheries Service (collectively, the “Services”) rescinded their 2020 final rule that established a regulatory definition of “habitat” for the purpose of designating critical habitat under the Endangered Species Act (“ESA”) (“Final Rule”). 87 Fed. Reg. 37,757. That 2020 final rule defined “habitat” as “the abiotic and biotic setting that currently or periodically contains the resources and conditions necessary to support one or more life processes of a species.” The Final Rule rescinding this definition goes into effect on July 25, 2022. After the rescission is effective, though critical habitat designations may proceed, they will do so under a cloud of uncertainty due to the lack of a regulatory definition for “habitat.”
Specifically, rescission of the 2020 “habitat” definition, without replacement, returns the Services to an approach that the Supreme Court in Weyerhaeuser Co. v. U.S. Fish & Wildlife Service, 139 S. Ct. 361 (2018) found to be an inadequate foundation for designation of critical habitat. Because the Services appear to be claiming broad discretion and flexibility in designating areas of critical habitat, this is likely to mean uncertainty, inconsistency, and lack of transparency in critical habitat designations, particularly for unoccupied areas. For example, it is not clear what type of “reasonable restoration” is necessary for an area to be designated critical habitat. The expanded regulatory authority and uncertainties over what may qualify as critical habitat under the ESA are likely, at least for now, to result in the requirements for such designations being resolved and clarified through litigation.
More broadly, the Final Rule is the first in a series of anticipated actions by this Administration that will significantly revise the ESA regulatory framework. As the Services have noted in the Spring 2022 Unified Agenda, other forthcoming actions include, but are not limited to, those related to:
- Rescission of critical habitat exclusion procedures (expected July 2022).
- Revising regulations for listing species and designating critical habitat (expected October 2022).
- Revising regulations for permits for take of endangered species (expected October 2022).
- Revising regulations governing experimental populations (expected November 2022).
- Reinstating protections for species listed as threatened under ESA (expected January 2023).
- Revising regulations for interagency cooperation (expected February 2023).

In a related development, on July 5, 2022, the U.S. District Court for the Northern District of California vacated three Trump era ESA rules: Regulations for Listing Species and Designating Critical Habitat, 84 Fed. Reg. 45,020 (modified how the Services add, remove, and reclassify endangered or threatened species and the criteria for designating listed species’ critical habitat); Regulations for Prohibitions to Threatened Wildlife and Plants, 84 Fed. Reg. 44,753 (eliminated the FWS’s former policy of automatically extending to threatened species the protections against “take” that Section 9 automatically affords to endangered species); and Regulations for Interagency Cooperation, 84 Fed. Reg. 44,976 (changed how the Services work with federal agencies to prevent proposed agency actions that could harm listed species or their critical habitat). The Services had filed a motion to remand without vacatur, but the court deemed vacatur appropriate at this time.
