The distribution of chest-level diameters was simulated in two different ash stands of uniform age. Present distribution is simulated on the basis of arithemtic means, standard deviations and the number of trees. Future distribution (after 10 years) is simulated by the addition of the one- year radial growth of each tree for a series of 10 years. This growth is calculated for each simulated tree as a linear function of its diameter with the addition of the product of standard deviation in the direction of equalized growth and the u-variable, the value of which is determined by random number.
