In the Batang Toru watershed with 380 tail pupulasi density of about 0.47 to 0.82 fish per square kilometer. The population of Sumatran orangutans (Pongo abelii lesson) is now estimated at 7500 head. Whereas in the era of the 1990s, an estimated 200,000 fish. Their population is at 13 separate geographical regions. These conditions led to their survival increasingly threatened with extinction. Currently almost all sumatera orangutans are found only in the province of North Sumatra and Aceh province, the Lake Toba as the most southern boundary spreading. 2 Only a relatively small population in the southwest of the lake, the East Sarulla and forests in the West Batang Toru. Largest orangutan population in Sumatra, found in the West Leuser (2508 individuals) and East Leuser (1052 individuals), and Swamp Singkil (1500 individuals). Another population estimated potential to survive in the long term (viable) is in Batang Toru, North Sumatra, with a size of about 400 individuals.

In Borneo, orangutans can be found in Sabah, Sarawak, and almost all the lowland forests of Borneo, except South Kalimantan and Brunei Darussalam.
