Trump Redefines ESA 'Harm,' Dropping Explicit Habitat Protections for 1,600 Species
3 articles · Updated · Vox.com · Jul 20
Summary
A new Trump administration rule published this month says destroying habitat for endangered and threatened species is no longer explicitly illegal under the Endangered Species Act; it takes effect in September.
The change scraps a decades-old definition of “harm” that covered habitat damage impairing breeding, nesting or other essential behavior, and instead backs a narrower view focused on direct, intentional injury to individual animals.
That shift could weaken Habitat Conservation Plans that let developers and utilities operate legally while offsetting incidental harm, because those permits were built around the broader definition now rescinded.
Federal critical-habitat protections for agency actions remain in place, but environmental groups have already sued, setting up a court fight that could reach the Supreme Court after the 2024 end of Chevron deference.
The rule follows other July ESA rollbacks, including easing protections for threatened species, and critics say it could strip the 1973 law of much of its power to prevent extinctions.

The 2026 ESA Rollback: How New Rules Threaten U.S. Species and Spark Legal Uncertainty
Overview
On July 10, 2026, the Trump administration finalized major changes to the Endangered Species Act, officially publishing a new rule that eliminates automatic protections for threatened species. Now, the U.S. Fish and Wildlife Service decides protections on a case-by-case basis, which could allow activities like killing or trapping species such as the pygmy rabbit or Florida manatee. The rule also redefines what counts as 'harm,' narrowing protections and sparking widespread concern among conservation groups. These changes mark a significant shift in how threatened species are managed and have immediate impacts on wildlife protection.
