Abstract
Forest thinning is a complex of forestry measures aimed at improving the qualitative and quantitative indicators of the stand, the formation of highly productive, sustainable and economically valuable stands, by removing sick, damaged, fallow trees, as well as trees of undesirable species in young stands, stumps and middle-aged stands. The work presents a comparison of the normative indicators for the two rules of forest maintenance, the main difference of which is the approach to the allocation of the maximum allowable felling stock, based on the analysis of the absolute, for the new standard, and the relative, for the old, completeness of the stand. The evaluation and comparison of classes of marketability, percent of the harvested stock and its distribution across the plots were made in order to identify the differences and peculiarities of the approaches of the two normative approaches under consideration. By results of the carried out analyses it was revealed difference of the forest inventory data to real qualitative and quantitative indicators of a stand on the majority of plots, the big difference between classes of marketability on the considered standards that in turn leads to distinctions in an exit on stocks of business and wood, and as their qualitative distinction, and intensity of thinning of a canopy that is caused by the above-named features on allocation of the maximum allowable cut stock. In connection with the above stated, it is necessary to develop regional norms of forest tending on the basis of received long-term observations on permanent trial areas with a full cycle of conducted forest tending and, if necessary, to make corrections, the possibility of which is fundamentally excluded by the existing scheme of development and introduction of normative documents.
