    Description

    A large portion of logging residues and materials removed in thinning consists of trees 1 to 10 inches dbh (diameter at breast height). As part of research to achieve increased utilization of these small trees, whole-tree weight tables and prediction equations were developed for small Appalachian hardwoods, based on a sample of 200 trees of 17 species from a site in central West Virginia, Average green weight of the trees (all material above a 6-inch stump) was 433 pounds, 80 percent of which was in material greater than 3 inches d.o.b. (diameter outside bark). The weighted average moisture content of the 200 trees was 69 percent, oven-dry basis. Whole-tree weight tables (green and oven-dry basis) were developed from the formulas: Ln(GWT) = 1.54934 + 2.39376 Ln (DBH) and Ln (ODWT) = 0.95595 + 2.42640 Ln (DBH); where GWT= whole-tree green weight in pounds, ODWT = whole-tree oven-dry weight in pounds, DBH = diameter breast high, and Ln = natural logarithm function.
