The ecoregion covers an area of 3,600 square kilometers (1,400 sq mi) on both the eastern and western sides of the peninsula. The peat swamp forests have formed over hundreds of years, as sediment and organic debris deposited by rivers are trapped behind mangroves, gradually building up a layer of waterlogged, acidic, nutrient-poor soil.
Peat swamp forests occur where waterlogged soils prevent dead leaves and wood from fully decomposing, which over time creates thick layer of acidic peat.The peat swamp forests on Borneo occur in the Indonesian state of Kalimantan, the Malaysian state of Sarawak and in the Belait District of Brunei on coastal lowlands, built up behind the brackish mangrove forests and bounded by the Borneo ...
1.1 Tropical and subtropical moist broadleaf forests. 1.2 Montane grasslands and shrublands. ... Malaysia is a megadiverse country, with huge variety of biota.
About 62% of the world's tropical peat lands occur in the Indomalayan realm (80% in Indonesia, 11% in Malaysia, 6% in Papua New Guinea, and pockets in Brunei, Vietnam, the Philippines, and Thailand). [ 6 ] [ 7 ] Peat in Indonesia is distributed over three islands, Sumatra (8.3 million ha), Kalimantan (6.3 million ha) and Papua (4.6 million ha).
[clarification needed] [57] To create viable soil for plantation, the mires in tropical regions of Indonesia and Malaysia are drained and cleared. The peatland forests harvested for palm oil production serve as above- and below-ground carbon stores, containing at least 42,069 million metric tonnes (Mt) of soil carbon. [59]
Tropical peat is a type of histosol that is found in tropical latitudes, including South East Asia, Africa, and Central and South America. [2] Tropical peat mostly consists of dead organic matter from trees instead of spaghnum which are commonly found in temperate peat. [ 3 ]
The environment of Malaysia is the biotas and geologies that constitute the natural environment of Malaysia. Malaysia's ecology is megadiverse, with a biodiverse range of flora and fauna found in various ecoregions throughout the country. Tropical rainforests encompass between 59% and 70% of Malaysia's total land area, of which 11.6% is pristine.
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. Orangutan in Sabah, Borneo
