The Endangered Species Act (“ESA”) has seen a 99% success rate in protecting listed species since its inception in 1973. After celebrating its 52nd anniversary this year, there are diverging views about how to continue to advance this success while developing efficiencies in the decision-making process. Most recently, the US Fish and Wildlife Service (“USFWS”) published four proposed rulemakings in quick succession that generated thousands of comments from the public, zoo and animal foundations, and other interested parties. The four proposed rules specifically relate to listing and delisting decisions, interagency cooperation and consultation, allowance of economic factors in decision-making, threatened species protection, and critical habitat exclusions. The comment deadline for all four proposed rules was December 22, 2025, despite requests from multiple organizations for an extension of the comment period to March 2026. Over 300,000 comments were received on each proposed rule prior to the deadline.
