Wetlands International Indonesia Programme

Rawa Lakbok has peat deposits which comprise an area of 3,000ha with a maximum depth of 6m. It is probably the largest peat area on Java and maybe even the largest topogenous peat marsh in Indonesia. The peat deposits originated in a basin which to the South and West is bordered by hills culminating in the Gunung Sangkur. To the Northwest the Gn. Mandalare is situated. Those elevations are separated by a depression through which in former times water from the Ci Tanduy flowed into the Rawa. A narrow mountain ridge at the Southeastern side separates Rawa Lakbok from Rawa Biuk. The Rawa Lakbok rises to 10m a.s.l. in the Northern part, gently sloping to 6.5m in the Southern part; drainage takes place through a gap in the mountain ridge which lies between the Lakbok and the Biuk. The Biuk drains through the Cilisung into the Ciseel; the Lakbok it self has no apparent drainage stream. Principal vegetation: Reclamation of the area was begun as early as 1924. Clearing of the original vegetation has been so drastic that the former impenetrable swamp was reshaped into a bare, tree-less plain with only sawahs and swampy fallow lands. In 1949 only at the plantation Langen a small patch of swamp forest was left. Species that are now rare in Java occurred there: Ficus retusa, Elaeocarpus littoralis, Nephralepis radicans, Scirpodendron ghaeri, Flascopa scandens, Stenochlaena palustris, Licuala sp. This forest can (could?) be regarded as a peatswamp forest in status nascendi, like the forest at Banjarmasin (Polak 1949). No information is available on the present situation, and the peatswamp forest may well have disappeared.
