The Udzungwa rainforest is a remnant of the ancient Eastern arc rainforest that stretched along the eastern rift. It has similarities with forests in Madagascar and West Africa. However, Madagascar split from the mainland 165 million years ago and the Udzungwa forests have remained isolated from those in West Africa for the last 5 million years so that there exists a high degree of endemism with 25% of the plant species unique, 4 species of endemic primate, and several recently discovered endemic bird species.
