Individual Tree Biomass Models for Plantation Grown American Sycamore

Abstract

Individual tree volume and green and dry weight equations are derived for American sycamore from a 5-year-old plantation in southeast Arkansas. Two trees have been destructively sampled each year from each of 20 plots. Observations from 168 trees are used to predict tree weight and volume as a function of dbh, total height, age, and initial number of trees. Separate component equations are given for bole wood, bole bark, branch wood, and branch bark. Additivity of the predicted component values is discussed. Based on fit index and the coefficient of variation. the sum of the predicted component values are good estimates of total bole, branch, and tree volume and weight.
