Green and Dry-Weight Equations for Above-ground Components of Planted Loblolly Pine Trees in the West Gulf Region

Abstract

Prediction equations based on 130 sample trees from thinned and unthinned loblolly pine (Pinus taeda L.) plantations in central Louisiana are presented for the green and dry weights of aboveground tree components. Sample trees ranged from 2 to 21 in. dbh, 18 to 94 ft in height and from 9 to 55 yr in age. Significant differences in partial stem weight between trees from thinned and unthinned stands required development of separate sets of weight ratio equations. The range of the studies' observations increases the predictive applicability of planted loblolly pine biomass equations. South. J. Appl. For. 11(4):212-218.
