The tree is very sensitive indicator to the com-plex of ecological factors of variability of phytocenosis which is reflected in properties of its wood. Biological and technical properties of wood from positions of high-quality display of influence of climatic, anthropogenous, chemical and other ef-fects are important for ecological assessment of the tree. From ecological position various changes of properties of growing tree in mutual coordination with the complex of ecological factors forming for-est phytocenosis were considered. In ecological assessment central place is taken by the determi-nation of quantitative and qualitative parameters of wood. Indicators of the macrostructure of wood are indicators of ecological situation in forest phytocenosis. Researches included forest stands of a pine ordinary of natural origin, growing in various types of ecological conditions. At the statement of material usual standards and recommendations were used. In best ecological conditions species, larger by the sizes, were formed. It should be noted some tendency to increase in width of year layers, increase of percentage of late zones of wood of pine ordinary at improvement of forest vegetation conditions. Now the main attention is focused on ecological assessment of biological and technical properties of wood that improves tools of carrying out commercial assessment of forest phytocenosis. In this regard ecological requirements come to the forefront and become the basis for economic as-sessment of separate tree as system component of forest ecosystem. The obtained data can be rec-ommended for use in cultivation of quality forest plantings, and also at target forest growing of forest cultures with the best indicators of properties of wood.
