Description: The article presents of the stem diameter distri bution rows in the natural diameter classes with considering of the trees quality categories. These rows are formed of six main tree species in Belarus: pine, spruce, oak, birch, black alder and aspen. The use of such series together with the assortment tables allows you to commodification of the rated cutting without the use of timber quality tables. Method of calculation is described in detail. To perform this operation it is necessary for each element of forest in the stand to know the average diamet er and height, absolute or relative density, and the proportion of merchantability trunks or class quality of wood. For the case where the proportion of the merchantability trunks don’t known, but there is only class quality of wood, the article presents the average percentage of merchantability trunks depending on the species and class quality of wood. Present method of fitting the series averaged distribu tion of the natural thickness steps of the concrete forest element preserves all the relationships that occur between the total number of trees, the number of merchantability and fuel trunks on the diameter clsass and for the whole element of forest.
