East Kalimantan Sebuku Sembakung National Park

Sebuku Sembakung National Park

The Sebuku – Sembakung National Park is the most recent addition to Indonesian’s list of proposed National Parks. The park comprises an area of 400,000 ha. and is bounded on the west by the Kayan Mentarang National Park. Together with this park, the Sebuku Sembakung National Park contains an undisturbed sequence of all major habitats in Kalimantan, ranging from the mangrove forests, tidal swamp forests, fresh water and peat swamp forests, riverine forests and lowland forests of Sebuku Sembakung to the hill and mountain habitats from Kayan Mentarang.
The western area of the Sebuku watershed comprises forested hills with limestone areas and outcrops. Although limestone areas are recognized as areas with unique biological and cultural values they have been unrepresented in Indonesia’s protected area network so far. A current World Bank sponsored project is investigating limestone ecosystems in order to improve management and prevent unsustainable developments in these unique areas.
The central part of the reserve is a good quality example of lowland forest including a flat lowland plain supporting the only known population of Elephants in Kalimantan. Lowland forest is one of the most threatened habitats in Kalimantan both as a result of the 1997-98 forest fires and logging activities. WWF Indonesia hopes that the establishment of the Sebuku Sembakung National Park will compensate for the loss of this biodiversity-rich habitat type in other areas in Kalimantan.
Muara Sebuku, at the easternmost part of the site, is the best and least disturbed mangrove forest in Kalimantan, the only area left in the region without shrimp ponds. The area also comprises about 10,000 ha. of peatswamp forest.
The area is almost completely uninhabited and only accessible for the real adventurers. Nunukan could be your base. If you don’t know where to find this, don’t go.
There is no accommodation inside the reserve.
