Figure 1From: Linking acoustic velocity of standing Douglas-fir trees to veneer stiffness: a tree-log-product study across thinning treatmentsRelative density (top) and stand stocking density (bottom) from the time of establishment to harvest for Douglas-fir thinning treatments A through E at Sites 803 (left) and 808 (right). Vertical lines connect density before and after thinning. Darker colours represent increased thinning intensity.Back to article page
