The relationship D = β(H − 1.3) / ln (N) illustrated for 202 measurements in 25 plots of even-aged Eucalyptus grandis in Queensland, Australia, with 2 trajectories illustrating the temporal development of individual forest stands. Data span the years 1941–87, and a range of stocking 80–1075/ha, of mean diameter 1–72 cm, and of stand height 1–56 m (Data from Mattay and West 1994).
