Spread out between the Katingan and the Sebangau Rivers, just at the outskirt of Palangkaraya,, the Sebangau National Park in Central Kalimantan is one of the last remaining peat swamp forests in Borneo. The vast national park covering approximately 568,700-hectare is home to over 6,000 orangutans, forming one of the world’s largest populations in the wild. Aside from its rich biodiversity, the forest is also known for its special ecosystem: that of the black water ecosystem. This particular ecosystem was created from decomposing organic matter living in these peat swamps, resulting in the blackened water and the unique variety of organisms.

The World Wildlife Fund (WWF) Indonesia campaigned to establish the park, which was gazetted in 2004, and the organizaton remains at the forefront at involving nearby residents in low-impact logging, home industry, reforestation and ecotourism. Thus, providing balance harmony between the preservation of Orangutan and the community.
