The U.S. Fish and Wildlife Service (FWS) announced the removal of the gray wolf (also known as the “grey” wolf) from the ESA in March 2019, citing the overall population's health in all nine extant states. The species had spent 45 years on the list, and the two primary populations greatly exceeded recovery goals among the Northern Rocky Mountains and Western Great Lakes.
