The paper presents of the research of the quality of the artificial Japanese larch stands established on the site of the mountain beech forests in Chemernik (Serbia). On the selected sample plots, based on the studied stand condition, environmental conditions and analysis of the development of trees and silvicultural needs, the low selective thinning of high and moderate weigh was suggested as the silvicultural measure. In addition, the trees were classified based on the biological location, as well as the quality of stems and crowns. The three-degree classification was applied, which means that the trees were classified as dominant, codominant, or depressed trees, and at the same time the quality of stem and crown of each tree on the sample plots was estimated. By analysing the obtained results of the quality and biological position of the trees, the quality of the stand was evaluated prior and after the marking for thinning. The stable stand of the better quality has a greater influence on the creation of the more favourable microclimate of the vinicity, on the mitigation of the temperature extremes, and it enables the increase of the relative air humidity by the evapotranspiration, as well as the reduction of the concentration of the air pollutions, etc.
