Abstract
The peat swamp forest, one of the most peculiar types of vegetation in Southeast Asia, is found in Borneo, Sumatra and Malaysia on domeshaped, oligotrophic and acid peat. The characteristics of this forest include the dominance of Shorea albida, which attains more than 60m height and covers extensive areas of Sarawak and Brunei in unistratal pure stands. The vegetation on the peat shows the zonation from the margin to the center of the peat, where the dwarfed, high density, pole-size forests appear. Major components in each zone and species characteristics of Shorea albida are described. Forest types in Sarawak and Brunei are compared with those in Sumatra and Kalimantan.
