Borean Orangutan

Bornean Orangutan

Bornean orangutan populations have declined by more than 50% over the past 60 years, and the species' habitat has been reduced by at least 55% over the past 20 years.

The Bornean orangutan differs in appearance from the Sumatran orangutan, with a broader face and shorter beard and also slightly darker in color. Three subspecies are recognized, each localized to different parts of the island:

• Northwest Bornean orangutans are the most threatened subspecies. Its habitat has been seriously affected by logging and hunting, and a mere 1,500 individuals or so remain. Many habitat patches in the area are small and fragmented.
• Northeast Bornean orangutans are the smallest in size and found in Sabah and eastern Kalimantan as far as the Mahakam River.
• Central Bornean orangutans are the subspecies with the most animals, with at least 35,000 individuals.
