Core Action and Immediate Effect
On July 14, 2026, the U.S. Department of the Interior and the U.S. Department of Commerce issued a final rule rescinding the regulatory definition of “harm” from the 1973 Endangered Species Act (ESA). The rule, published in the Federal Register, takes effect on Sept. 14, 2026. Previously, “harm” encompassed “significant habitat modification or degradation” that could kill or injure wildlife by impairing essential behaviors such as breeding, feeding, or sheltering.
Historical Context
The definition was first added in 1975, revised in 1981, and upheld by the Supreme Court in 1995 ( *Babbitt v. Sweet Home Chapter of Communities for a Great Oregon* ) as covering habitat destruction. The ESA, enacted in 1973, has been credited with preventing extinction of 99 % of listed species.
Key Figures and Organizations
- Doug Burgum, Secretary of the Interior – announced the change.
- Howard Lutnick, Secretary of Commerce – co-announced the rule.
- Kristen Boyles, Earthjustice attorney – lead plaintiff in lawsuits.
- Tara Zuardo, senior campaigner, Center for Biological Diversity – co-plaintiff.
- Jane Davenport, senior attorney, Defenders of Wildlife – plaintiff.
- Swinomish Indian Tribal Community and Squaxin Island Tribe – tribal plaintiffs.
- Industry supporters include the American Petroleum Institute and the Associated General Contractors of America.
Official Statements & Responses
The Interior Department said the rule “returns the interpretation of the ESA back to its actual text and original intent,” aiming to reduce “unnecessary permitting, cut compliance costs and eliminate confusion.” A NOAA Fisheries spokesperson added that the revision will “maintain protections for endangered species while reducing unnecessary or duplicative permitting requirements.” Industry groups praised the move as relieving “unnecessary regulatory burdens” and supporting “American energy leadership.”
Criticism & Opposition
Environmental groups argue the rescission removes a critical tool for protecting habitats, risking species such as salmon, marbled murrelet, northern spotted owl, and Siskiyou Mountain salamander. Boyles called the repeal “a violation of the statute’s core purpose and decades of legal precedent, including from the U.S. Supreme Court.” Zuardo warned that eliminating habitat from the definition “means you’re not going to be able to protect any of the listed species.” Tribal plaintiffs contend the loss of habitat protection will “injure the Tribes and their members.”
Impact and Legal Outlook
Lawsuits have been filed in federal district courts in Seattle and Oregon, seeking to block the rule. Plaintiffs anticipate “countless individual projects will be held up in court” and an increase in litigation over projects that do not protect habitat. The rule could make logging, mining, and road construction easier on federal lands, potentially accelerating habitat loss.
Conflicting Reports & Gaps
The administration claims the rule will “maintain protections for endangered species,” while opponents cite scientific consensus that habitat loss is the primary driver of extinction. No independent impact assessment has been released, leaving uncertainty about how the narrowed definition will affect specific species recovery plans.
Verbatim Quotes
- “The Trump Administration repeal violates the core purpose of the statute and decades of legal precedent, including from the U.S. Supreme Court. Now more than ever, imperiled species from salmon to marbled murrelets to grizzly bears need habitat protection to survive and recover,” — Kristen Boyles, Earthjustice attorney
- “For years, federal agencies abused the ESA to obstruct lawful land use and burden American families and businesses,” — Doug Burgum, Secretary of the Interior
- “We’re returning the ESA to its foundational purpose to ensure legitimate conservation goals are met without sacrificing economic growth and American prosperity.” — Howard Lutnick, Secretary of Commerce
- “the loss of long-standing protection for the habitat of ESA-listed salmon species will injure the Tribes and their members.” — Swinomish Indian Tribal Community (complaint)
What’s Next
The rule becomes enforceable on Sept. 14, 2026. Ongoing litigation in Seattle and Oregon will determine whether the definition can be reinstated or further modified. Courts are expected to issue preliminary injunctions that could pause the rule’s application pending final decisions.
