The country is one of the most varied and important fauna reserves in Africa:[2] it is an important refuge for chimpanzees (whose number, in 2003, was estimated between 27,000 and 64,000)[citation needed] and gorillas (28,000-42,000 estimated in 1983).[3] The "Gorilla and Chimpanzee Study Station" inside the Lopé National Park[citation needed] is dedicated to their study.
