Sampling for Above-Ground Biomass for Pinus radiata in the Bosboukloof Catchment at Jonkershoek

Abstract

A sampling trial for the estimation of the above biomass was undertaken in the Bosboukloof catchment at Jonkershoek State Forest. Eighty-five trees were felled, after which the oven-dry weight of stem-wood, bark, branches and foliage was estimated by subsampling. The weight of stemwood and bark of each sample tree was obtained from a subsample within each tree, that of branchwood and foliage by the application of regression analysis to combined subsamples of branches.
