Arizona at a glance

The Mexican gray wolf once roamed throughout most of Arizona, New Mexico, Texas and Mexico; however, persecution and, eventually, poisoning began shortly after European settlement. On March 29, 1998, eleven captive-reared wolves were released into the Blue Range Wolf Recovery Area. This reintroduced population is shared by Arizona and New Mexico. Main prey for wolves there are elk, deer and domestic livestock. Much controversy surrounds these wolves, due in large part to depredation (killing livestock) issues. Wolves in Arizona range in less than 5 percent of the map shown. Range lines are not depicted.
