Zasnova poskusa redčenj bukovih sestojev v raziskovalnem objektu Brezova reber

Z namenom analize učinkov redčenj bukovih sestojev so v raziskovalnem objektu Brezova reber postavili tri bloke, pri čemer vsak blok vključuje tri ploskve. Vsaki od ploskev znotraj blokov so naključno določili obravnave: klasično izbiralno redčenje (obravnava A), izbiralno redčenje s stalnimi izbranci (obravnava B), kontrolna ploskev, prepuščena naravnemu razvoju (obravnava C). Spomladi 2011 so izmerili in ocenili drevesa na ploskvah. Nato so analizirali ničelno stanje na ploskvah, določili izbrance in odkazali drevje za posek. Ugotovili so, da so razlike med bloki majhne, znotraj bloka pa precejšne. Obravnavi A in B sta se razlikovali zlasti v številu odkazanih dreves na izbranca in v deležu odkazanih dreves glede na celoten sestoj.In order to study thinning effects of beech stands on Brezova reber research three blocks with three plots within each block were set up by us. Following treatments were randomly selected for each plot within all block: classical selective thinning (treatment A), selective thinning with fixed crop trees (treatment B), control plot for natural development (treatment C). In spring 2011 the trees on plots were measured by us. Then starting points on the plotswere analyzed, the crop trees and their competitors were selected. The differences between the blocks were found out small, while within the block are being considerable. Moreover, the differences between treatments A and B in the number of selected competitors per crop tree and in the share of the competitors in total stem number were established by us
