The Park sprawls across the floor of the Semuliki Valley on the remote, western side of the Rwenzori. The Park is dominated by the easternmost extension of the great Ituri Forest of the Congo Basin making the park to be one of Africa’s most ancient and bio-diverse forests. Semuliki Valley also contains numerous features associated with central rather than eastern Africa making it to be the only park in Uganda that perfectly combines the ecosystems of Eastern Africa with those of Central Africa. This park provides shelter for 120 mammals, including several primate species such as baboons and chimpanzees, as well as elephants and antelopes. There are around 350 species of birds hosted in this forest, including 23 Albertine Rift endemics.
