Bwindi Impenetrable National Park 

It is one of the largest places in East Africa with Afromontane lowland forest that extends well into the montane forest zone, covering 32,092 ha. The property, which is thought to be a Pleistocene refugium and is located on the eastern end of the Albertine Rift Valley, is a biodiversity hotspot with possibly the greatest number of tree species for its altitude in East Africa.

It also has a rich biodiversity, including several rare butterflies and one of Africa's most diverse mammalian assemblages. As an isolated forest of extraordinary biological richness surrounded by an agricultural landscape supporting one of the highest rural population densities in equatorial Africa, the property represents a conservation frontline as home to over half of the world's mountain gorilla population. Mountain gorilla and other ecotourism-related community benefits may be the sole hope for the continued protection of this unique environment.

The Bwindi Impenetrable National Park was named a UNESCO World Heritage Site in 1994.
