Abstract
Distributions of Scotch pine trees by categories of sanitary condition, Kraft classes and classes of merchantability, as well as by index of sanitary condition of plantation were analyzed after 30 years after their creation. It was found that influence of trees disposition in the plot and initial density of trees on their distribution by sanitary condition loses its significance over time. Index of sanitary condition of stands indicates their weakening on all sections of experimental plot. The part of trees belonging to І and ІІ Kraft classes amounts 87–98 %. It was proved that timeliness and quality of thinning affects essentially on the investigated parameters.
