We, the U.S. Fish and Wildlife Service (Service), determine endangered status under the Endangered Species Act of 1973, as amended, for the Mexican wolf (Canis lupus baileyi). The effect of this regulation will be to revise the List of Endangered and Threatened Wildlife by making a separate entry for the Mexican wolf. We are separating our determination on the listing of the Mexican wolf as endangered from the determination on our proposal regarding the delisting of the gray wolf in the United States and Mexico. This rule finalizes our determination for the Mexican wolf.
