Trump Rules Weaken Endangered Species Act by Redefining 'Take' and 'Harm'

The Trump administration has finalized two regulations that narrow the meaning of 'take' and 'harm' under the Endangered Species Act, according to reporting from Grist and CleanTechnica. The changes remove longstanding regulatory language and, in effect, weaken protections for hundreds of listed species. Both outlets describe the move as a major rollback of the nation's cornerstone conservation law.

One rule rescinds the federal definition of 'harm' and took effect in mid-September. The Sierra Club and conservation partners filed suit to block it, CleanTechnica reports, while state officials and some lawmakers are also working to reverse the change. The rule is among the latest administrative actions to test how far the executive branch can go in reinterpreting existing environmental statutes.

The sources agree on the central facts: the administration is changing regulatory definitions, and environmental groups are pushing back. They differ mainly in framing. Grist treats the dispute as a contest over the meaning of two simple words, while CleanTechnica emphasizes the regulatory process and the immediate legal response. Neither outlet suggests the outcome is secure; the litigation and state actions are ongoing.
