Mentawai have the highest levels of endemic primates in the world.

We are working to stop them from going extinct

The Mentawai Islands are made up of 4 islands: Siberut, Sipora, North Pagai, and South Pagai. The tropical rainforest on these islands holds some of the most endemic biodiversity in the world. In 1993, the western part of the island of Siberut, covering 190,500 hectares, was designated as a National Park. However, the Islands of: Sipora, North Pagai, and South Pagai remain unprotected, leaving many endemic primates today on the brink of local extinction.
