The forest plays vital role in economy of the most countries.

It is a source of wood and food, has recreational, sanitary-hygienic, curative, soil-protective, water regulative and other significances. Increase of necessities of societies and economies in wood and useful functions of the forest causes new requirements to forestry.

Scientific researches, which perfect knowledge about the features of growth, morphology and ecology of stands in general, help to find solution to these requirements. Study about the features of yield of beech stands is necessary and substantial element of general cognition about morphology of the forest, elaboration of scientific theoretical conclusions and applied recommendations concerning utilization of forest resources.

The goal of work was comparison of growth and productivity of beech stands of plane part of western Ukraine and southern Sweden and determination of reliability of the comparable yield tables in both countries relying on data of permanent sample plots. Analysis of deviations of the basic inventory indexes on all sample plots regarding data of the yield tables and estimate of Student’s criterion point at possibility of reliable determining of the inventory indices by using Swedish and Ukrainian yield tables created on basis of site condition.

Site conditions and approaches concerning forming and growing in Ukraine and Sweden do not enable to recommend one of the type of analyzed yield tables for an estimation and prognosis of development of beech stands in both countries. This research is important first of all for determination of regularities of growth of the beech stands in different climatic conditions. Results demonstrate different character of growth and development of the stands in investigated conditions.
