The obtained regression model for the estimation of beech stand volume structure per diameter classes is intended for the case when the average volume per hectare is calculated using a model or tables. The model consists of two independent variables: mean diameter of a diameter class and the percentage of basal area of a diameter class. It is based on a high correlation between relative distributions of basal area and stand volume per diameter classes. The distribution of basal area per diameter classes in this case is determined by the relascopy method. The model is statistically precise, but its accuracy in practice depends directly on the accuracy of the calculated distribution of the stand basal area per diameter classes, i.e. on the accuracy of the calculated average stand volume per hectare.
