Whether reintroduction and recovery should be allowed, and if so where and how, were hotly debated through the 1990s, when reintroduction was formally proposed. They still are. Regardless, the proposal process ended with a nonessential experimental population rule (hereafter Final Rule) approved on January 12, 1998. In keeping with the stated experimental nature of the reintroduction effort, and respectful of the doubts expressed by many, the Final Rule required full evaluations after 3 and 5 years to recommend continuation, modification, or termination of the Reintroduction Project. The 3-Year Review, conducted in 2001, concluded that reintroduction should continue, albeit with important modifications. However, as we discuss elsewhere in this report, for many reasons the 3-Year Review recommendations were not implemented, at least not to the extent that interested parties and stakeholders expected or desired. Regardless of cause, the apparent lack of closure was a significant agency and public concern when the time came for the next review.

By agreement among the primary cooperating agencies, responsibility for the Reintroduction Project’s 5-Year Review fell to the Mexican Wolf Blue Range Adaptive Management Oversight Committee (AMOC) that oversees the Project on behalf of six Lead Agencies and various formal and informal Cooperator agencies. AMOC and the Project's Interagency Field Team conducted the 5-Year Review to comply with the Final Rule, but above and beyond that the intent was to identify and implement improvements in the Project. The Review consists of several primary components: Administrative, Technical, Socioeconomic, and Recommendations. Each is detailed in this report. Review and adaptive management of the Reintroduction Project will not stop with this review. Project cooperators will continue to seek internal and public input regarding Mexican wolf reintroduction to help achieve recovery goals and objectives.
