The overall goal of the strategy is, as an immediate challenge, to lift the threat of imminent extinction facing most populations of great apes, namely gorillas, chimpanzees, bonobos (pygmy chimpanzees) and orangutans, and, beyond that, to conserve in their natural habitats wherever they exist, wild populations of all species and subspecies of great ape, and to make sure that, where they interact with people, those interactions are mutually positive and sustainable.
