Udzungwa Mountains National Park is lies in the Iringa and Morogoro regions of south-central Tanzania where it is bordered by the Great Ruaha River to the north and by the road between Mikumu and Ifakara to the east. The major attraction of the park is its bio-diversity and unique rainforest where many rare plants, not found elsewhere in the world, have been identified. For this reason Udzungwa is being proposed as Tanzania's eighth World Heritage Site. The park is home to eleven types of primate. Five of these are unique to Udzungwa, including the endangered Iringa red colobus monkey and the Sanje crested Mangabey. The plateau also supports populations of elephant, buffalo, lion and leopard. Visitors should not expect to necessarily see these larger species however as they tend to be found in the less accessible area of the park. Bush baby or galago, bush pig, civet, duiker, honey badger and three types of mongoose are more likely to be seen. The park is also home to a number of rare forest birds many only found in this area of Tanzania.
