abstract = "A simulation model of diameter increment and thinning for Cupressus lusitanica, Pinus patula, and Pinus radiata growing in Kenya, Tanzania, Uganda, and Malawi is presented. The diameter distribution is defined by a vector of diameters corresponding to fixed cumulative probability points. Increment of the diameter vector is a function of basal area relative to maximum basal area, diameter relative to dominant diameter, and height as a site-dependent index of age. A general algorithm for simulating thinning of the cumulative distribution is developed based upon the probability that a given stem will remain after thinning. Validation studies using permanent sample plot data for the 3 species show a standard deviation of percentage residuals for total volume prediction of 12-19 percent; they also show, through simulation of spacing experiments, that the model is accurate over a range of initial stockings from 120 to 1,400 stems/hectare.
