Reintroduction, in the context of organisms, is a conservation method involving the deliberate translocation and release of individuals from captive populations or donor wild populations into parts of their historical range where the species has been extirpated. It is typically implemented under formal management plans that define source populations, genetic and demographic criteria, health screening, quarantine, transport protocols, soft- or hard-release strategies, and post-release monitoring. Methodological considerations include founder number and structure, minimizing inbreeding and outbreeding depression, habitat suitability assessment, threat mitigation, and adaptive management based on demographic, behavioral, and genetic feedback from the reintroduced population.
Another of the wolves released in Colorado earlier this year as part of the state's reintroduction effort has died, wildlife officials said Friday.
