The Great Apes Survival Partnership (GRASP) is an innovative and ambitious project of the United Nations Environment Programme (UNEP) and the United Nations Educational, Scientific and Cultural Organization (UNESCO) with an immediate challenge - to lift the threat of imminent extinction faced by gorillas (Gorilla beringei, G. gorilla), chimpanzees (Pan troglodytes), bonobos (Pan paniscus) and orangutans (Pongo abelii, P. pygmaeus) across their ranges in equatorial Africa and south-east Asia.
