Weight and Volume of Plantation-Grown Choctawhatchee Sand Pine
The aboveground green weight of the total tree and its major components, the main stem and crown, were determined in eight stands of planted Choctawhatchee sand-pine ranging in age from 7 to 27 years. Eighty-three trees, ranging in d.b.h. from 0.7 to11.1 inches from 11 to 59 feet in total height, were sampled. After testing for significant differences, data were stratified to provide two sets of composite equations: one for the six stands with a closed canopy, i.e., ages 12 to 27 years, and one for the young stands where crown closure had not yet occurred. Equations for predicting individual tree green and dry weights and cubic volumes of wood, and of wood and bark, were developed for the main stem and crown of each canopy class.Ratio equations were developed to allow estimation of weights and volumes to specified top stem diameter. Tables for estimating green and dry weight and cubic volume are given for the total tree and its major components, based on d.b.h. and total height.
