Meratus Mountains

The Meratus Mountains is a mountain range in the Indonesian province of South Kalimantan; it is located on Borneo island. The mountains run in a north-south arc that divides South Kalimantan province into two almost equal parts. Its highest peak is Mount Besar with 1,892 metres.
The mountains are inhabited by the "semi-nomadic" Meratus Dayak people.
In the 1990s the Borneo Orangutan Survival Foundation reintroduced 350 orangutans into the protected Meratus and Sungai Wain forests. Due to extensive deforestation the ecosystem of the mountains, including many flora and fauna species are endangered. Traditional Dayak villages are also disappearing.
