The U.S. Fish and Wildlife Service (Service) is the lead agency responsible for recovery of the Mexican wolf, pursuant to the Endangered Species Act. The Mexican Wolf Recovery Program essentially is separated into two, interrelated components: 1) Recovery – includes aspects of the program administered primarily by the Service that pertain to the overall goal of Mexican wolf recovery and delisting from the list of threatened and endangered species, and 2) Reintroduction – includes aspects of the program implemented by the Service and cooperating States, Tribes, and other Federal agencies that pertain to management of the reintroduced Mexican wolf population in the Blue Range Wolf Recovery Area, which consists of the entire Apache and Gila National Forests in Arizona and New Mexico. This report details all aspects of the Mexican Wolf Recovery Program.

Species re-establishment is the attempt to establish a species in an area which was once part of its historical range, but from which it has been extirpated or become extinct in the wild. Pima County and other agencies have proposed to re-establish species at a number of sites. Relevant laws and regulations governing re-establishment efforts are discussed. Case studies illustrate how previous efforts have been conducted and how the populations have fared.
