Survival Remains High in Griffon Vultures 40 Years After Reintroduction
Animal Conservation, EarlyView.The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management
