Green and Dry-Weight Equations for Above-ground Components of Planted Loblolly Pine Trees in the West Gulf Region
Prediction equations based on 130 sample trees from thinned and unthinned loblolly pine (Pinus taeda L.) plantations in central Louisiana re 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 stan...

متن کاملSimple, flexible, trigonometric taper equations
THOMAS, C. E., and PARKESOL, B. R. 1991. Simple, flexible, trigonometric taper equations. Can. J. For. Res. 21: 1132-1137. There have been numerous approaches to modeling stem form in recent decades. The majority have concentrated on the simpler coniferous bole form and have become increasingly complex mathematical expressions. Use of trigonometric equations provides a s imple expression of tap...
