INFLUENCE OF THINNING ON BIOLOGICAL AND FIRE SUSTAINABILITY OF PINE FOREST STANDS

In the article given the results of researches of the effect of thinning of different intensity on the biological and fire sustainabilityof high-density middle-aged pine forest stands of natural and artificial origin which grown in dry forest conditions(forest type C2) in the state forest natural fenced reserve «Semey ormany». The study of the biological sustainability of pineforest stands was conducted on the basis of the index of forest damage and a complex of the estimated indicators or coefficientof tension growth (CTG). It is noted that the studied pine forest stands before logging characterized as damaged and weakened.It is found that after thinning different intensity, there was a reduction of damage of the forest stand and the coefficient of tensiongrowth. In the results of thinning different intensity the studied pine forest stands on all sections on the index of forest damage(Dv) characterized as healthy and by the value of the coefficient of tension growth characterized as biologically stable. In thiscase, the value of the index of damage depending on the intensity of thinning is in natural stands 10.2; 7.8; 6.8 % in low, moderateand heavy thinning, and plantations of artificial origin 18.7; 12.1 and 12.4 percent, respectively. Coefficient tension growthin natural and artificial pine plantations after thinning weak, moderate and strong intensity amount to 8.3 ± 0.4; 7.6 ± 0.4; and7.0 ± 0.4 (for natural), 7.3 ± 0.3; 6.7 ± 0.4; 6.8 ± 0.3 cm/cm2 (for plantations). It is found that the removing of dry brancheson the trees to the height of 2.5–3 m contributes to the fire resistance of pine forest stands, as well as improves their aestheticperception and recreational appeal. These activities become important in forests growing around the human settlements.
