Muara Sebuku Nature Reserve

Sebuku

Latitude : 4 4 7 N Logitude : 117 22 27 E
Altitude : 0 to 100 metres
Area : 110000 ha Wetlands: 110000 ha

Site Description
The site is an estuarine system with deltas, where three rivers end: the Semanggaris, Sebakis, and Sebuku rivers. Tinabasan and Sebaung are the largest deltas. In this estuarine system, extensive mangrove forest occur. Principal vegettion incluses Rhizophora and Avicennia.These two genera dominates the sea-ward side of the estuary. Upstream of the three rivers, Nypa belt occurs along the river bank of the rivers. The mangrove forest is considered the remaining best and least disturbed mangroves left in the province East Kalimantan (55,000 ha). Also includes some peatswamp (10,000 ha) of high importance to fisheries and important as habitat for the Proboscis Monkey. To the south, outside the proposed conservation area, extrensive peat swamp forest occur on Gambut land system, particularly between Sebuku, Sembakung and Sesayap rivers. The condition of peat swamp forest during the 1997 airial survey, was relatively in good condition. Based on the survey, it was observed that the condition of mangrove forest at the south of the Sebuku estuary (e.g. Baru island, Bangkudulis besar island, Tibi island) is not as good as at Sebuku estuary. At these sites, a lot of clearings occur, and the mangrove forests are converted to fishponds (tambak). Cathment area of the above rivers are generally forested, although logging activities occur.
