Site Description
Jelai river is one of the main rivers that run through peat swamp forest on Gambut Land System. The estuary of Jelai river is about 700 m wide with some nypa palm belt and coconut plantation at the river banks. No mangrove vegetation occur at the estuary. Kuala Jelai village is located at the Central Kalimantan-side river bank of this estuary. Some small villages and sawmills occur along the river, including the Nataikuini village. The banks of Jelai river are vegetated with 10-m wide nypa belt. At the back of nypa belt, some open areas (with bushes and alang-alang) commonly occur, particularly at the Central Kalimantan side. At this eastern bank, a broad cleared belt of riparian forest which stretches more or less uninterrupted from the distance, occur. On the western bank, there is a mosaic of forest and clearings. Further upland peat extensive peat swamp forest occur on a deep peat soil. Some lake systems occur. One of the largest is known as Lake Gelanggang. This lake is a blackwater oxbow lake which originally from Jelai river. The lake is 5 km long and 2.5 km wide with a depth between 1.5-3 metres. Some smaller lakes occur upstream of Jelai river. Peat swamp forest on Gambut and Mendawai land systems are the main water catchment area for Jelai river. The peat swamp forest is relatively in good condition and undisturbed, particularly near lake Gelenggang (WIBOWO, 1997). Further upstream, the some forest clearings occur. The Gambut land system in this site is the only remaining peat swamp forest occur at the south part of West Kalimantan.
