Species Re-Establishment Within Pima County: Sonoran Desert Conservation Plan

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.
