H.R. 4255 — Enhancing Safety for Animals Act of 2025

This section delists the Mexican wolf (Canis lupus baileyi) by removing it from the lists of endangered and threatened species published pursuant to section 4(c) of the Endangered Species Act of 1973 (16 U.S.C. 1533(c)), notwithstanding any other provision of law. It nullifies two U.S. Fish and Wildlife Service final rules on the Mexican wolf: (1) "Endangered and Threatened Wildlife and Plants; Endangered Status for the Mexican Wolf" (80 Fed. Reg. 2488; Jan. 16, 2015); and (2) "Endangered and Threatened Wildlife and Plants; Revision to the Nonessential Experimental Population of the Mexican Wolf" (87 Fed. Reg. 39348; July 1, 2022). Additionally, if the Mexican wolf is relisted under the Endangered Species Act, it prohibits the Secretary of the Interior from considering the status of Mexican wolves in Mexico when developing recovery plans under ESA section 4(f) (16 U.S.C. 1533(f)) or making future listing determinations under ESA section 4(c) (16 U.S.C. 1533(c)).
