U.S. finalizes new Endangered Species Act rules for threatened species and critical habitat
The U.S. Fish and Wildlife Service finalized two Endangered Species Act regulatory revisions on July 17 that will change how federal agencies handle future threatened-species listings and critical-habitat designations nationwide.
One revision ends the future use of a blanket rule under Section 4(d) of the law. Instead of automatically receiving protections equivalent to those provided to endangered species, species listed as threatened in the future will receive protections tailored to the individual species.
The second revision changes procedures under Section 4(b)(2), which governs how the government evaluates proposed critical habitat. The revised process includes criteria for weighing economic impacts, national-security concerns and other relevant considerations. It also allows an area to be excluded from a critical-habitat designation when the exclusion would not cause the species to become extinct.
What changes for future listings
The Section 4(d) revision applies to future threatened-species listings. It does not, by itself, remove protections from species that are already listed as threatened, and it does not constitute a species-specific decision.
Under the revised approach, federal protections for a newly listed threatened species will be developed according to that species’ circumstances rather than through an automatic default framework. The Fish and Wildlife Service described the change as a way to make protections more tailored and predictable.
That means the practical consequences will emerge through later listing and implementation decisions. The July 17 announcement did not identify individual species or projects immediately affected by the change.
Critical-habitat exclusions
Critical habitat identifies areas that are important to the conservation of a species protected under the Endangered Species Act. The revised Section 4(b)(2) procedures address when the government can weigh impacts beyond the biological value of a proposed area.
Economic and national-security effects are specifically included among the considerations. The revised rules also address exclusions, allowing an area to be left out of a critical-habitat designation when doing so would not cause the species’ extinction.
The change could affect future decisions involving land use, infrastructure, development and conservation planning. It does not guarantee that any particular project will be approved or that any particular habitat will be excluded. Those outcomes will depend on future agency decisions involving individual species and locations.
A separate rule on “harm”
The July 17 action was the second major ESA regulatory development announced by the Fish and Wildlife Service in July. A separate final rule published July 14 rescinded the regulatory definition of “harm” from the federal Endangered Species Act regulations.
That rule involves the Fish and Wildlife Service and NOAA Fisheries and is identified as Federal Register citation 91 FR 43300. It is scheduled to take effect on September 14, 2026.
Together, the July actions represent three major Endangered Species Act regulatory actions announced or published during the month: the two revisions finalized July 17 and the separate rule concerning the definition of “harm” published July 14.
The revisions are administered through federal Endangered Species Act regulations and apply nationwide. The agencies’ stated policy goal is to make species protections more tailored and predictable, while the effects on species recovery, habitat protection, land use and conservation planning will depend on how the revised rules are applied in future cases.
