Aim of the work – to analyze the regularities of quality rates variation and to make the evaluation models of birch assortment structure, concerted with Europe Union standard’s requirements. Object of the work – semi mature and mature birch forests. During research there were used measurement data of birch stems quality rates (diameter, bark thickness at full stem length) and round wood defects. Methodology of the research – there were measured pruned birch stems, filled in the model wood card, indicating the forest and the model wood characteristics. After this empirical database was structured and normatives were made, which allow to evaluate the volume of timbers of various diameter and high trees A, B, C and D quality classes, paper wood, firewood and waste wood.
