Only two mountain gorilla populations exist in the world, but the good news is that the larger of two has grown by 10 percent in the past decade, according to conservation groups. About 355 gorillas live in the Virunga mountain range spanning Rwanda, Uganda, and the Republic of Congo, despite armed conflict in the area that has threatened the primate’s habitat for the past several years. About 15 gorillas have been killed as a “direct consequence of war,” says the African Wildlife Federation, although poaching and a general lack of resources for conservation have also taken a toll on the population. A second group of mountain gorillas, numbering about 300, lives in the Impenetrable Forest of Uganda.
