Book excerpt: Abstract: Total weights and volumes, above stump, were determined for 71 northern red oak (Quercus rubra L.) trees 6 to 24 inches d.b.h. growing in fully stocked oak-hickory stands in western North Carolina. Equations are presented for predicting green and dry weights and green volume of the total tree, above stump, and its components using d.b.h. and total height, d.b.h. and height to a 4-inch top, d.b.h. and saw-log merchantable height, and d.b.h. along. Tablesdeveloped from equations show weight and volume of the total tree and it components by d.b.h. and total height classes. Seventy-five percent of total-tree weight was in stem to a 4-inch top and 25 percent in crown. The average tree had 85 percent of its green weight in wood and 15 percent in bark. Total-tree wood had an average specific gravity of 0.581, and average moisture content of 80 percent, and an average green weight per cubic foot of 65 pounds. The average weightof wood and bark per cubic foot of wood for the total tree was 77 pounds.
