Trump administration rescinds Endangered Species Act habitat harm rule, opening protected land to development

The rule change

On Friday the administration finalized a regulation that rescinds the definition of "harm" under the Endangered Species Act of 1973. For decades, federal agencies had interpreted the term to include any significant modification or degradation of habitat that kills or injures wildlife by impairing essential behaviors such as breeding, feeding or sheltering. The Supreme Court upheld that interpretation in 1995. The new rule removes this habitat-protection language, meaning that destroying a nest or the area where an imperiled animal lives would no longer be legally considered harm.

The change could open up vital ecosystems to farming, fossil-fuel extraction, real estate development and other commercial activities. Environmental lawyers warned that species already squeezed by habitat loss will face extreme added pressure. The text of the final rule had not yet been published in the Federal Register as of late Friday.

Justification from the administration

The Interior Department, which oversees federal lands, said the rollback restores the Endangered Species Act to its original intent and ends years of regulatory overreach.

For years, federal agencies abused the ESA to obstruct lawful land use and burden American families and businesses.

Interior Secretary Doug Burgum added in a statement that the previous rule turned routine activity into a regulatory trap and expanded federal authority beyond what Congress intended. The administration argued that environmentalists had weaponized the act to block drilling and other development nationwide.

Environmental response and legal threat

Conservation groups reacted sharply. Earthjustice attorney Kristen Boyles announced that the organization would challenge the repeal in court, calling the administration’s move unsupported by science, law or public sentiment.

Let's be clear: there is no support for the Trump Administration's rule -- no scientific support, no legal support, no public support.

Tara Zuardo of the Center for Biological Diversity framed the issue in stark terms.

If animals no longer have a place to live, they cannot survive.

The groups emphasized that habitat protection has been a cornerstone of the law’s success since its passage in 1973, credited with saving species such as the bald eagle and the American alligator.

Broader rollback of environmental rules

The habitat-harm repeal is one part of a wider effort by the Trump administration to weaken the Endangered Species Act. In March, a panel of administration officials voted to exempt oil and gas operations in the Gulf of Mexico from measures safeguarding whales and other marine species. The administration is also moving to repeal a regulation that gives threatened species the same protections as endangered ones, and to revise another rule so that regulators must weigh economic considerations when designating critical habitat. Officials indicated that further changes would be announced in the coming weeks.
