The majority of Uganda's biodiversity is found in southwestern Uganda along the Albertine Rift Valley. The western arm of Africa's 4,000 mile Great Rift Valley was created by two parallel tectonic plates that crashed together millions of years ago. As the plates pulled apart, huge landslides, erosion and the collapse of the plate edges fromed the rift. The Albertine Rift is edged by some of the continent's highest mountains, including the Virunga, Mitumba and Rwenzori Ranges, and the rift floor includes some of the world's deepest lakes.
The Ugandan portion of the Albertine Rift enjoyed its heyday in the late 1950's and early 1960's when tourists flocked to the game parks around Queen Elizabeth and Murchison Falls, instead of going to Kenya and Tanzania, These parks were homke to more than 30,000 elephants, 7000 rhinos, 10,000 zebras, 26,000 hippos, 60,000 Cape buffalo and 25,000 hartebeest. The Ugandan Albertine Rift had the highest recorded mammalian biomass for any place on Earth. But high human density, conflict and poaching have taken their toll, leaving only about 20% of these levels and rhinos are unfortunately extinct.
The Albertine Rift stretches from the northern tip of Lake Albert in Uganda to the southern tip of Lake Tanganyika in northern Zambia. The natural habitat within this eco-region, comprised of portions of the Democratic Republic of Congo (Zaire), Uganda, Rwanda, Burundi, Zambia and Tanzania, is equally diverse, ranging from glaciers at the top of the fabled Rwenzori Mountains, down through alpine moorland, forest lands and savanna grasslands.
These landscapes support high levels of species richness and endenism. According to Wildlife Conservation Society, the Rift is the most species rich Africanregion for vertebrates, This area of Africa contains 52% of all bird species anf 39% of all mammals species found on the African continent. However, this eco-regionis even more important for the number of endemic species - those that are unique to this area and found no where else on Earth. The Albertine Rift has more endemic species of plants and animals than any other eco-region on the African continent.
