Vultures populated the Causses region until the 19th century. Victims of their bad reputation, these birds of prey had completely disappeared - hunted, poached, or for lack of food - and were last seen in 1945. From the beginning of the 1980s, a reintroduction program was launched by the Cévennes National Park, the LPO (League for the Protection of Birds) and the Raptor Intervention Fund on the cliffs of Jonte site, around the ravine of Cassagnes. After an inaugural failure, the operation finally succeeded thanks to a different method. The vultures are bred in an aviary and released only after couples have been formed.
