Korup Jungle

The Korup forest forms part of the great belt of evergreen rainforest between the Cross River and the Gulf of Guinea. It shelters the drill, a large forest monkey, and Preuss's red colobus, whose range is restricted to forests of the Nigeria–Cameroon borderlands. Streams in the Korup country belong to several different drainage systems, including the upper Cross and the Ndian. The forest was part of a refuge for rainforest species during the last glacial period.
