Experimental conversion fellings in pine stands of East Polissya
Journal Title: Лісівництво і агролісомеліорація - Year 2015, Vol 126, Issue
Abstract
Experimental combined conversion fellings were conducted in weakened middle age pure artificial pine stands. Active experiments consisted of 5 variants of thinning: formation of square, rectangular, strip and rounded gaps, with the use of thinning in a renewal stripe joining to the gap and without it as well as even thinning. Intensity of the thinning on the plot was about 25 % of standing volume. For retention of pine stand stability the best results were obtained for variants with the rounded gaps having a cross-sectional size of 1,0 mid height of pine stand, and also for square and rectangular gaps (of 1,0–1,5 mid height of the stand). The best conditions for regeneration of principal species are formed in a seminal year on the plots of autumn and winter harvesting. After conversion felling in a spring and summer period it is required to implement measures for assistance to regeneration for the principal species (soil loosening, seeds sowing or planting of seedlings of principal species).
