Trump Announces New Wildlife Rule

The Trump administration has implemented a major change to the way the federal government enforces the Endangered Species Act, potentially reducing liability for businesses and landowners when protected wildlife is harmed indirectly during otherwise lawful activities.

The change could have significant consequences for logging, construction, farming, energy development and other industries that operate in areas inhabited by endangered or threatened species.

Under the new federal approach, the government has eliminated its longstanding regulatory definition of “harm,” which previously allowed certain habitat destruction that actually killed or injured protected wildlife to qualify as an illegal “take.”

The new rule became effective September 14, 2026.

Trump Administration Narrows Endangered Species Rules

The U.S. Fish and Wildlife Service and NOAA Fisheries formally removed the regulatory definition of “harm” from federal Endangered Species Act regulations.

For decades, that definition allowed federal officials to consider certain indirect actions — including significant habitat modification — when determining whether someone had illegally harmed a protected species.

The Trump administration argues that interpretation stretched the law beyond what Congress originally authorized.

The Interior Department says the change restores the Endangered Species Act to what officials believe is the proper reading of the statute while reducing unnecessary regulations for American businesses, farmers, ranchers and property owners.

Direct actions against protected wildlife remain prohibited under the law.

What the New Rule Could Mean

The practical difference centers on intent and the connection between a person’s actions and the death or injury of an animal.

For example, federal guidance has indicated that cutting down a tree containing protected bats would not necessarily amount to illegally taking those bats simply because they were harmed as a result.

That could represent an important change for companies conducting logging, construction or development projects.

Previously, businesses sometimes needed federal permits even when killing protected wildlife was not the purpose of a project.

The administration says the former system placed excessive burdens on lawful economic activity.

Environmental organizations argue the new interpretation could make it more difficult to protect animals from predictable habitat destruction.

Property Rights and Federal Regulation Take Center Stage

The dispute is also part of a much broader debate over the authority of federal agencies.

Supporters of narrower environmental regulations have long argued that agencies should enforce laws according to the language approved by Congress rather than expanding those laws through administrative interpretations.

The Interior Department says the policy will provide greater regulatory certainty for landowners, small businesses, energy producers, farmers, ranchers and local governments.

Officials also cited the Supreme Court’s 2024 decision in Loper Bright Enterprises v. Raimondo, which ended the Chevron doctrine that had previously given federal agencies significant latitude when interpreting ambiguous statutes.

That Supreme Court decision has prompted agencies across the federal government to reconsider regulations that depend heavily on administrative interpretations of federal law.

Endangered Species Protections Have Not Disappeared

Despite the regulatory change, the Endangered Species Act remains in effect.

Activities that directly kill, wound, hunt, shoot, trap, capture or collect protected wildlife can still violate federal law.

Existing permits and incidental-take statements also remain valid, according to the Interior Department.

The key change involves indirect harm associated with activities such as modifying or destroying habitat.

That distinction could affect how many businesses and property owners need federal approval before beginning projects.

Businesses Could Face Fewer Permitting Requirements

Under the previous approach, developers and businesses often worked with federal wildlife officials before proceeding with projects that could affect protected species.

Companies could obtain incidental-take permits that allowed limited harm to wildlife as part of an otherwise lawful activity.

Those permits frequently came with habitat conservation plans and other measures designed to reduce environmental damage.

Under the Trump administration’s narrower interpretation, some companies may conclude that such permits are unnecessary when their activities are not directly aimed at protected wildlife.

However, some businesses may continue seeking permits to reduce legal uncertainty.

Future presidential administrations could change the rules again, and environmental organizations may continue challenging particular projects in federal court.

Environmental Groups Warn About Habitat Loss

Conservation organizations strongly oppose the new approach.

Their primary concern is that habitat destruction is one of the leading threats to endangered wildlife.

Critics argue that limiting federal liability for indirect harm could allow development projects to move forward even when companies know protected animals are likely to be killed or displaced.

Environmental groups also contend that Congress intended the Endangered Species Act to provide broad protections capable of preventing extinction before populations reach a crisis point.

The administration rejects the argument that the change abandons conservation.

Federal officials say the government’s fundamental protections against directly killing or capturing listed wildlife remain intact.

A Supreme Court Battle From 1995 Remains Important

The controversy has a long legal history.

In the 1995 Supreme Court case Babbitt v. Sweet Home Chapter of Communities for a Great Oregon, the court upheld the government’s broader interpretation of “harm” under the Endangered Species Act.

The ruling supported the government’s ability to regulate certain habitat changes that resulted in the death or injury of protected wildlife.

Justice Antonin Scalia dissented and favored a narrower interpretation of the law.

The Trump administration’s current approach more closely reflects that narrower view while also relying on more recent Supreme Court decisions limiting federal agency authority.

The competing interpretations could once again end up before federal judges.

Why the Endangered Species Act Matters

Congress passed the Endangered Species Act in 1973.

Over the following decades, the law became one of the federal government’s most powerful wildlife conservation statutes.

It has been associated with recovery efforts involving well-known American species including the bald eagle, American alligator and California condor.

At the same time, the law has frequently generated disputes over land development, agriculture, logging, energy production and private property rights.

Those conflicts have made the Endangered Species Act a recurring issue whenever presidential administrations change.

Trump and Biden Took Different Approaches

The regulatory battle has shifted repeatedly in recent years.

During President Trump’s first term, his administration reduced several Endangered Species Act regulations.

President Joe Biden’s administration subsequently reversed a number of those policies.

After Trump returned to office, his administration began restoring several of the earlier regulatory changes.

In July 2026, the Fish and Wildlife Service announced additional revisions involving threatened-species protections and the designation of critical habitat.

Federal officials say those changes are intended to provide more flexibility while maintaining protections required by the law.

What Happens Next

Legal challenges are likely to determine how durable the new interpretation becomes.

Environmental organizations and several states have challenged various Trump administration environmental policies, while industry groups and property-rights advocates have pushed for limits on federal regulatory authority.

The stakes extend beyond wildlife conservation.

The dispute could affect construction projects, energy development, forestry, agriculture and private property across the country.

For businesses and landowners, the administration’s approach could mean fewer federal restrictions when protected wildlife is affected indirectly.

For conservation groups, it raises concerns that fewer habitat-related activities will face federal scrutiny.

The ultimate question now facing the courts is how broadly Congress intended the Endangered Species Act’s protections to reach — and how much authority federal agencies have to interpret those protections.
