The Mexican gray wolf subspecies was listed as endangered in 1976. In 1998 a nonessential experimental population was established in New Mexico and Arizona. Eleven captive-born and reared animals were released into the Blue Range Wolf Recovery Area. In June 2007, the U.S. Fish and Wildlife Service contracted with D.J. Case and Associates to assist in planning and implementing public input for a scoping process to identify issues to consider in developing alternatives preparatory to development of a new Environmental Impact Statement for the Mexican gray wolf introduction program.
