Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus Pongo, orangutans were originally considered to be one species. Orangutans are the only great ape outside of Africa and they are uniquely adapted to the tropical forests of Southeast Asia. During the Pleistocene, orangutans ranged throughout forests in Java, Sumatra, Borneo, Vietnam and southern China. As climate slowly changed over nearly 1.8 million years, the orangutan range shifted southward. Orangutan populations have declined dramatically, perhaps by as much as 97%, in the 20th century (1) due to hunting and forest loss. Today orangutans are patchily distributed in fragmented lowland forests in Borneo and Sumatra. Tanjung Puting contains one of the largest and most concentrated populations of wild orangutans in the world.
