The park is covered by a huge Tropical Rainforest comprising of about 2500 different species of plants thus forming a habitat for different living creatures. It is a continuation of the famous Eastern Arc Mountain chains with their origin in the southern part of Kenya (Taita hills) running through North and South Pare, East and West Usambara, Nguu, Nguru, Uluguru, Ukaguru, Rubeho, Malundwe, Mahenge, Udzungwa and ending in Makambako Forest. The park is unique by harboring some of the endemic flora and fauna which cannot be found anywhere on earth except Udzungwa hence referred to as the ”centre of endemism”.
