Gorilla [SEP] Conservation status
All species (and subspecies) of gorilla are listed as endangered or critically endangered on the IUCN Red List. Now, over 100,000 western lowland gorillas are thought to exist in the wild, with 4,000 in zoos, thanks to conservation; eastern lowland gorillas have a population of under 5,000 in the wild and 24 in zoos. Mountain gorillas are the most severely endangered, with an estimated population of about 880 left in the wild and none in zoos. Threats to gorilla survival include habitat destruction and poaching for the bushmeat trade. In 2004, a population of several hundred gorillas in the Odzala National Park, Republic of Congo was essentially wiped out by the Ebola virus.
