The United States has undergone significant regulatory shifts regarding the Endangered Species Act. Following reforms finalized by the Trump administration that narrowed habitat protections, legal scrutiny has intensified regarding wildlife fatalities caused by industrial operations. For instance, ESI Energy, a subsidiary of NextEra Energy, was ordered to pay over $8 million in fines and restitution and received five years of probation after findings that it killed at least 150 bald and golden eagles at wind facilities.

Building on these regulatory changes, the U.S. Fish and Wildlife Service issued a directive in September reinterpreting the legal definition of a ‘take.’ Under a memo signed by Director Brian Nesvik, the incidental or unintentional killing of protected wildlife may no longer be considered illegal if the action was not specifically intended to target the animal. This directive clarifies that indirect impacts, such as a vessel striking a whale or felling a tree used by bats, do not constitute a ‘take’ unless the action was performed with the explicit purpose of killing or capturing the species.

This redefinition effectively excludes accidental deaths resulting from lawful economic activities—including commercial fishing, logging, or industrial development—from federal prosecution. The administration maintains these changes return the law to its original intent, citing a 2024 Supreme Court decision regarding federal agency authority. Environmental advocacy groups and former wildlife officials have criticized the move, arguing it creates a ‘massive loophole’ that relieves industries of responsibility for the foreseeable consequences of their actions on imperiled species.

- Under the new interpretation, killing an endangered species is only illegal if the act is intentionally directed at the animal. (corroborated by 11 sources)
- The reinterpretation excludes deaths caused indirectly by activities such as commercial fishing or logging. (corroborated by 11 sources)
- The change allows companies to engage in activities like logging or dam building even if they know it could kill protected species. (corroborated by 4 sources)
- The administration claims the move returns the Endangered Species Act to its original intent following a 2024 Supreme Court decision. (corroborated by 4 sources)
