Trump administration narrows ‘harm’ under Endangered Species Act, allowing habitat destruction
Trump administration’s July 10, 2026 rule narrows ‘harm’ under the Endangered Species Act, allowing habitat loss critics say endangers wildlife across the US.
The Biden-era interpretation of the Endangered Species Act was replaced on July 10, 2026, when the Interior and Commerce Departments finalized a rule that narrows the definition of “harm.”
Under the new rule, activities that alter or destroy habitat will no longer automatically be treated as illegal “harm” unless they directly kill or injure a listed animal, a change officials say restores statutory intent.
Federal agencies frame the change as restoring statutory limits
The Interior and Commerce Departments issued a joint statement saying the rule returns the Endangered Species Act to its original meaning and limits federal reach.
Interior Secretary Doug Burgum said the prior interpretation had been used to block lawful land use and impose burdens on families and businesses, arguing the revision corrects regulatory overreach.
Supporters cast the move as a rollback of regulatory uncertainty that had delayed projects and raised costs.
Trade groups such as the National Mining Association praised the rule, saying the previous broader reading of “harm” served as an impediment to essential projects and investment.
What the rule changes in practice
For more than five decades, agencies treated “harm” to include significant modification or degradation of habitat that impairs an animal’s ability to feed, shelter or reproduce.
The final rule rescinds that broader definition and limits enforceable “harm” to direct injury or mortality of protected animals, meaning many alterations of nesting, breeding or feeding sites will not automatically trigger federal penalties.
The agencies said permits and prohibitions will still apply in cases where an action directly crushes, buries or injures an endangered animal.
But routine land uses such as tree felling, draining seasonal ponds or developing winter-vacant coastal sites may no longer be restricted under the same standards.
Scientists and conservationists warn of rapid habitat loss
Conservation groups and many scientists say habitat modification, not direct killing, is the primary driver of species decline and extinction.
They argue the new rule undermines decades of protections by allowing destruction of the places animals need to survive, reproduce and recover.
Experts point to species such as piping plovers that require undisturbed beaches for nesting, red-cockaded woodpeckers that depend on mature pine cavities, and California tiger salamanders that breed in seasonal ponds.
If those habitats are altered or removed during times when animals are absent, returning populations may find no viable breeding or foraging sites and decline precipitously, they warn.
Public response and state reactions were overwhelmingly negative
When the rule was proposed, it drew roughly 220,000 public comments, an analysis found, with the vast majority opposing the change.
State wildlife agencies in several Republican-governed states also urged reconsideration, warning that healthy habitats are essential to species survival.
Attorneys general from 16 states called the rationale “arbitrary, capricious, an abuse of discretion and contrary to law,” signaling legal challenges ahead.
Environmental law firms such as Earthjustice announced plans to sue, while conservation groups said the rule will reduce incentives for landowners to adopt habitat conservation plans or mitigation measures.
Industry backing and legal stakes
Oil, gas, mining and development interests supported the narrower interpretation, saying the broader reading of “harm” had been used to delay energy and infrastructure projects.
Trade associations argued the rule clarifies the scope of liability and reduces what they called unpredictable regulatory barriers.
Legal scholars note the next battles are likely to play out in federal courts and potentially the Supreme Court, where the current conservative majority could endorse or entrench the change.
If a court upholds the narrower definition, it could make it more difficult for future administrations to restore the prior interpretation without congressional action.
The rule is part of a broader pattern of deregulatory actions by the administration aimed at easing constraints on energy production, agriculture and development.
Critics say those steps, taken together, could accelerate biodiversity loss and make species recovery more difficult across the United States.
Public debate now centers on whether Congress or the courts will check the administration’s reinterpretation of the Endangered Species Act and on how states and private landowners will respond in managing critical habitat.
