We argue that UMAshave resultedin increasedintroduction of exotic species in an attemptto diversifythe sport-huntingopportunities and failedto economicallybenefit local communities.A lack of technicalcapabilities needed to conduct wildlifepopulation studies and evaluationsto assess harvest rates, favoritismin establishingthe UMAnetwork, and the lack of institutionalregulation have also impactedprogram success. We propose some solutionsthat could enhance the performance of UMAsand wildlifemanagement and conservationin Mexico.(WILDLIFE SOCIETY BULLETIN34(5):1480-1488; 2006) Key words communities,conservation, exotics, hunting,management, Mexico, UMAs,wildlife.

Access to this resource is regulated "patrimony of the nation for all Mexicans," creating what through law enforcement and hunting licenses (Geist 1985, might be considered by some as a de facto "Tragedy of the 1988).
