Diameter and height distribution recovery, in combination with standlevel projection modelling, is generally used in Southern Africa for predicting growth and yield in even-aged pine plantations. A different approach for modelling diameter and height distributions for five pine species commercially grown in this area, is investigated and described. Predicting standard deviation of diameters and the minimum diameter of the distribution, using inventory data are the key issues addressed. The height distribution is recovered indirectly from the predicted diameter distribution.
