According to Dr Ian Singelton of Sumatran Orangutan Conservation Program, the Tripa peat forest is home to the highest population density of Orangutan found anywhere on earth, but predicted to be locally extinct if current levels of forest clearing and conversion to plan oil plantation is not stopped immediately.

Oil palm producers have asserted that forests are not being cleared to grow oil palm. Our analysis of land-cover data compiled by the United Nations Food and Agriculture Organization suggests that during the period 1990–2005, 55%–59% of oil palm expansion in Malaysia, and at least 56% of that in Indonesia occurred at the expense of forests. Over Borneo and Sumatra as a whole, illegal logging has led to huge declines in orangutans and other wildlife. Where forests are converted to plantations of oil palm or other crops, the consequences are even more serious, with many orangutans starving.
The Sumatran orangutan is classified as Critically Endangered by IUCN. Since 1900, the number of Sumatran orangutans is thought to have fallen by about 91%, with a rapidly accelerating loss towards the end of the 20th century. Photo: Paul Hilton / Earth Tree Images
