The government of Cameroon --- with guidance from the Wildlife Conservation Society --- has created the world's first sanctuary exclusively for the Cross River gorilla, the world's rarest kind of great ape.
Classified as Critically Endangered by IUCN's Red List, the Cross River gorilla is the rarest of the four subspecies of gorilla.
The entire population numbers under 300 individuals across its entire range, which consists of 11 scattered sites in Cameroon and Nigeria.
