The biomass of various components of understorey plants of a Low land Dipterocarp Forest, between 1.5 and 5.0 m in height, was determined by harvesting 4 7 plants from a 0.01 ha plo t. The total above ground biomass was equivalent to 2 .7 8 tonnes/ha, and this was made up o f 81 percent stem , 7.5 percentbranch and 11.5 percent leaf. The le a f area index (L A I) o f the stratum was 0.36. Individual biomass of plant components and of the total plant was related to their collar girth. Using these regression equations, estimates based on m easurem ents o f collar girth in a 0.2 hap lot was found to be very close to that obtained by harvesting. This suggests that regression equations could be suitable for estimating biomass especially where no felling is allowed.
