Siberut is the largest in the chain of four Mentawai Islands situated off the west coast of Sumatra. It has been isolated from the Sumatra mainland and the Sunda Shelf for at least 500,000 years, resulting in an exceptionally high degree of endemism, 15% of the animals, of which 65% of the mammals are thought to be endemic. The island is home to five types of forest ecosystems: lowland dipterocarp rain forest is the principal ecosystem, mixed primary forest, swamp forests, coastal forests and mangroves.
