Gunung Leuser National Park

Gunung Leuser National Park is a national park covering 7,927 km2 in northern Sumatra, Indonesia. It straddles the border of North Sumatra and Aceh provinces. This national park, settled in the Barisan mountain range, is named after Mount Leuser (3,119 m), and protects a wide range of ecosystems. An orangutan sanctuary at Bukit Lawang is located within the park. Together with Bukit Barisan Selatan and Kerinci Seblat National Parks, it forms a World Heritage Site, the Tropical Rainforest Heritage of Sumatra. Gunung Leuser National Park is one of the two remaining habitats for Sumatran orangutans (Pongo abelii). In 1971, Herman Rijksen established the Ketambe Research Station, a specially designated research area for the orangutan. Other mammals found in the park are the Sumatran elephant, Sumatran tiger, Sumatran rhinoceros, siamang, Sumatran serow, sambar deer and leopard cat. Low-impact ecotourism can be one of the most important sustainable, nonconsumptive uses of Leuser, thereby giving local communities powerful incentives for conservation. Given the opportunities to view wildlife such as orangutans, some experts view ecotourism as a major potential source of revenue for communities living around Leuser.
