Every ecosystem has a “keystone” species, crucial to its balance. The legal system mirrors this, where pivotal laws like the Endangered Species Act (ESA) influence broader policies. Recent U.S. Fish and Wildlife Service amendments threaten to significantly alter the ESA, a concern voiced by environmental activists and agency leaders. They argue changes in the ESA’s language, particularly the definition of “take,” could undermine its effectiveness.
Earthjustice attorney Tim Preso noted efforts to weaken the ESA from various angles, highlighting the deregulatory agenda. The ESA, since its 1973 inception, has balanced species protection with human land use, mainly through prohibiting “take,” now redefined to exclude indirect harm like habitat destruction. This pivotal change in the ESA’s “take” definition could diminish its protective power, as argued by experts like University of Montana’s Sandra Zellmer.
The Federal Register’s recent notice rescinded the ESA’s definition of “harm,” aligning with goals since 2025 under the Trump administration. The shift means habitat alteration, even if detrimental to species, isn’t a “take,” affecting species reliant on specific environments. Preso lists additional plans targeting ESA authority, including revoking the “blanket rule” that protected threatened species, and changes in U.S. Forest Service policies that might impact grizzly bears.
Trump’s 2025 executive orders viewed the ESA as an obstacle to energy projects. These concerns are now part of a congressional bill aimed at reforming project permits, nearing Senate approval. The bill could mark a significant rollback of environmental protections, warns Erik Schlenker-Goodrich of the Western Environmental Law Center. The ESA’s changes face legal challenges, with Earthjustice representing various groups, including the Center for Biological Diversity.
The ESA, managed by multiple agencies, regulates activities impacting endangered species. Despite significant public opposition, FWS declined to extend the review or hold hearings on these major policy shifts. The debate over the ESA changes reflects a broader legal and ecological struggle, with several lawsuits already challenging the new rule’s interpretation and application.
