On Aug. 27, final revisions to the federal Endangered Species Act’s implementing regulations were published by the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) (collectively, the services). The Endangered Species Act (ESA) and its accompanying regulations and guidance have not undergone many changes since the law’s 1973 enactment. The Trump administration promulgated these changes to align the ESA program more closely to the administration’s goals of reducing regulatory constraints and increasing transparency. According to Commerce Secretary Wilbur Ross, the changes “fit squarely within the president’s mandate of easing the regulatory burden on the American public, without sacrificing our species’ protection and recovery goals.” As with many environmental policy developments in this current political atmosphere, however, public reaction has been split—many members of the regulated community have welcomed the changes, while environmental groups and several state attorneys general have sued the administration to overturn the rulemaking.

The ESA was enacted to aid in conservation of threatened and endangered plants and animals by providing them (and their critical habitats) with certain protections. According to the USFWS’ website, the ESA has prevented extinction for 99% of the species it protects. Among others, the ESA has protected several species previously at risk of extinction such as the humpback whale, grizzly bear and bald eagle.
