About 62% of the world’s tropical peat lands occur in the Indomalaya region (80% in Indonesia, 11% in Malaysia, 6% in Papua New Guinea, and pockets in Brunei, Vietnam, the Philippines, and Thailand. The spongy, unstable, waterlogged, anaerobic beds of peat can be up to 20 m deep with low pH (pH 2.9 – 4) and low nutrients, and the forest floor is seasonally flooded.[7] The water is stained dark brown by the tannins that leach from the fallen leaves and peat – hence the name blackwater swamps. During the dry season, the peat remains waterlogged and pools remain among the trees.
