The Trump administration has finalized a rule restricting the legal definition of “harm” under the Endangered Species Act (ESA), removing protections for critical habitats if the damage does not directly kill or injure a protected animal. According to U.S. officials, this change aims to reduce regulatory burdens on private landowners and businesses by adhering strictly to the 1973 text of the law.
Trump Administration Narrows “Harm” Definition in Endangered Species Act
The U.S. government has officially tightened the legal interpretation of what constitutes “harm” to a protected species. For nearly 30 years, federal agencies interpreted “harm” to include the “significant modification or degradation of habitat” that resulted in the death or injury of wildlife by disrupting essential behaviors like breeding, feeding, or sheltering. That interpretation is now over.

Doug Burgum, the U.S. minister charged with managing federal lands, stated in an official communiqué that federal agencies previously “diverted the ESA to hinder the legitimate use of land.” Burgum argues the new measure restores “common sense” and protects private property rights by applying the law exactly as Congress wrote it in 1973.
Environmental Groups Warn of Habitat Destruction
Conservationists argue that removing habitat protections creates a legal loophole for industrial expansion. Because the ESA prohibits the “taking” of species—which includes harassing, harming, pursuing, hunting, shooting, wounding, killing, trapping, capturing, or collecting—the definition of “harm” was the primary tool used to protect the land where these animals live.
Kristen Boyle, an attorney for the association Earthjustice, stated that this is the first time a presidential administration has asserted that protected species should not be shielded from habitat modifications that destroy their living and breeding grounds. Earthjustice has announced plans to challenge the measure in court.
Tara Zuardo of the Center for Biological Diversity warned that the change threatens the very survival of these animals, noting that “if the animals no longer have a place to live, they cannot survive.”
Comparing the Regulatory Shift
| Previous Interpretation (30 Years) | New Trump Administration Rule |
|---|---|
| “Harm” includes significant habitat degradation. | “Harm” is restricted to direct physical injury or death. |
| Protects breeding, feeding, and sheltering areas. | Prioritizes private property and “legitimate land use.” |
Potential Legal and Ecological Consequences
The shift moves the burden of proof. Under the previous rule, a developer or landowner might be barred from clearing a forest if that forest was essential for a species’ survival. Under the new rule, the activity may proceed as long as it doesn’t directly “kill” or “wound” the animal, even if the loss of the forest eventually leads to a population collapse.

Frequently Asked Questions
What is the Endangered Species Act (ESA)?
Adopted in 1973, the ESA is a major U.S. law designed to protect species at risk of extinction and the ecosystems they depend on.
What does “taking” mean in the context of the ESA?
According to the law, “taking” includes harassing, harming, pursuing, hunting, shooting, wounding, killing, trapping, capturing, or collecting a protected species.
How does the new rule change habitat protection?
It removes the interpretation that “harming” a species includes modifying its habitat. This makes it easier to develop land that was previously protected because it served as a critical home or breeding ground for wildlife.
