Cord, Volume, and Weight Relationships for Small Ponderosa Pine Trees in the Black Hills

摘要

Wood volume and oven-dry weight of wood and of bark can be reliably estimated from the combined green weight of wood and bark, with 97% of the variation being accounted for in predicting wood volume (cubic feet), 99% in predicting oven-dry weight of wood, and 91% in predicting oven-dry weight of bark. The average wood volume in sample cords was 72.8 cubic feet, for bolts from 5-7 inch trees, with a coefficient of variation of 3.2%.
