A new census finds a massive gorilla population previously unknown to scientists. WCS and the Government of Congo have tallied more than 125,000 western gorillas in the northern Republic of Congo. This is great news for the critically endangered western lowland gorilla, which had been believed to number only 50,000 in total.

A recent census conducted by WCS and other groups found that Uganda’s endangered mountain gorillas have increased in number, thanks in part to a thriving ecotourism program.

With support from WCS, the government of Cameroon creates the world’s first sanctuary exclusively for the Cross River gorilla, the rarest of the four gorilla subspecies.
