The habitat of the mountain gorillas is the tropical rainforests between the elevations of 2000 and 4000 meters. Ruanda only has about 400 of the animals left. Dian Fossey the American gorilla researcher and environmentalist (Gorillas in the Mist), has played an important role in developing awareness for the protection of these extraordinary animals.
