Abstract
Stumpwood biomass was estimated as part of a whole project in estimating the total biomass of tropical hill forest stand. Stumpwood is defined as having two components: the visible stump and the stump-root zone. Twenty-nine stumpwood samples were excavated. Their biomass, both green and oven-dry were regressed with all the measurable parameters and their transformations. It was found that the logarithmic transformation gave the best fit equation. Crown length instead of stump parameters and form product were two important variables in the equations. The equation predicted the stumpwood biomass of the hill stand, to be 10.83 tonne per hectare or 3.18% of the total above ground biomass. On the average the equation over estimated by 2.24%.
