Like any typical tropical rainforest, the main forest types within DTC include the lowland mixed dipterscamp rainforest which stratifies into three main layers with the top one rising to 45m in height. Underneath, on the forest floor is a layer of leaf-litter in various stages of decomposition. Besides the Lowland Dipterocarp Forest, there are the Hill Dipterocarp Forest, the thpper Hill Dipterocarp Forest and the Lower Montane Forest. The main tree species are from the Dipterocarpaceae family dominated by important commercial species of Shorea, Diperocarpus, Dryobalanops and Neobalanocarpus. Members of the non-Dipterocarpaceae family are mainly from Leguminosae, Sapotaceae, Burseraceae, Anacardiaceae and Myristicaceae.
