  1. Release captive-bred individuals to re-establish or boost populations in native range

    A review in 2008 of 49 studies in 1990–2006 of carnivore reintroductions in Africa, Europe, and North America (Jule et al. 2008) found that captive-bred animals released into the wild had lower survival than did wild-born translocated animals. Survival of captive-born carnivores following release (32%) was lower than survival of wild-born translocated animals (53%). The review analysed 20 reintroductions of 983 captive-bred carnivores and 29 reintroductions of 1,169 wild-caught carnivores. Post-release monitoring ranged in duration from 6 to 18 months.
