Bwindi Impenetrable National Park lies on the edge of the western rift valley. In the local Lukiga language, Bwindi means 'Impenetrable.'
The name is appropriate, for Bwindi Impenetrable National Park is 331 square kilometers (205 square miles) of tangled vegetation draped over a deeply fissured landscape of steep, slippery valleys and high, draughty ridges. The park, located at an altitude of 1,160 to 2,607 meters (3,800 to 8,550 feet), occupies different vegetation zones but predominantly is a tropical rain forest.
Bwindi Impenetrable National Park is a home to roughly half of the world's mountain gorillas. The park was established as a safe habitat for several families of mountain gorillas, and it is now the location of an important scientific conservation program. The park was declared an animal sanctuary in 1961, a national park in 1991, and a World Heritage Site in 1994.
Bwindi Impenetrable National Park is the richest, most species-diverse forest in Uganda and one of the richest ecosystems in Africa. Apart from the rare mountain gorillas, the park also has over 120 other species of mammal including 11 primates, including chimpanzee, black-and-white colobus, l'hoest monkey, and red tailed monkeys.
The forest is also rich in birdlife with 360 species, including short-tailed warbler, gruer's rush warbler, bar-tailed trogon, yellow-eyed black fly-catcher, dusky crimson wing, white-tailed blue monarch, wilcock's honey-guide, rusty-faced woodland warbler kivu ground thrush, among others. These birds cannot be easily cited anywhere in east Africa.
