Abstract

The article deals with the problem forest husbrandy of artificial pine forest, growing in rich, atypical for the Scots pine soil and environmental conditions. This question is particularly relevant for the Republic of Tatarstan, because there are large areas of pine forest plantations grow, and forest sites are represented mainly by heavy loamy and clayey soils. Thus, the purpose of the study was to evaluate the structure of artificial pine plantations growing under fresh surameney. The object of research was the plotted electronic database of forest and taxation indicators stands. The methodology of the study was consistent sorting and organizing raw data on the studied parameters. According to the research we revealed that plantations at the age of 31-50 years are dominated in the structure of artificial pine. According to participating the target type in the composition of shrub stands, the square of pure pine is dominated, linden participate in pine is 60-90%. Most pine forests are different by density of 0.7-0.8 relative units, but average density of older plantings is 0.6 and below. In conclusion it can be noted, that the most productive forest type within the TLU C2 are linden pines, which are mainly represented by Ia class of bonity and the stock more that 350 cubic meters per hectare at maturity. In the shrub pine forest management, it is necessary to give preference to mixed stands of hardwood with a share of 10-20% of the stock in the content. The main recommendations can be noted that the creation and cultivation of pine plantations in not peculiar to her circumstances fresh suremen, allows for intensive forest management.
