or Sabangau peat swamp forest (5,300 km2), between the Katingan and
Kahayan rivers. The peat swamp forest is a dual ecosystem, with diverse
tropical trees standing on a 10m - 12m layer of peat - partly decayed
and waterlogged plant material - which in turn covers relatively
infertile soil. Orang Utan in Sabah, Borneo
degraded eastern part of the forest, between the Sabangau and the
Kayahan, is officially designated for agriculture. However, since the

However, the western part is now protected as either
National Park or National Laboratory Research Area. A study of the area
shows that the hydrological integrity of the forest has been maintained,
and it is therefore ecologically resilient, although since it is
close to the regional capital Palangkaraya it remains at risk.

at 6,910 individuals in 2003, and other rare or unique species. The

monitoring in the forest.
