Young growth Douglas-fir, 16 to 24 inches in diameter, were felled and allowed to remain in the woods with various proportions of their crowns intact. Those trees with the greatest proportion of crown intact and that were least shaded lost the greatest amount of sapwood moisture. Significant reduction in moisture content and weight occurred after one month, with the maximum reduction attained after 3 to 4 months in the summer. Little drying occurred in the winter. Trees left without limbs sometimes gained moisture. Sapwood moisture contents ranged from lows of around 40 percent for trees with crowns intact to 140 percent for those with all limbs removed. The maximum difference in weight of wood on the variously treated trees was 20 pounds per cubic foot with 10-pound reductions being common after 3-4 months of transpirational drying. Bark and timber beetle attack varied with the drying condition of the trees.
