Prirodna regeneracija bukovih šuma u Srbiji
Natural regeneration of beech forests in Serbia
Izvod: Prirodna regeneracija bukovih šuma je istraživana u jedanaest visokih sastojina bukve na području Srbije. Sastojine su vrlo heterogene i po strukturi pretežno raznodobne, te se u njima preporučuje grupimično-oplodna seča, kao način obnavlјanja. Proces podmlađivanja je neplanski, a brojnost i kvalitet podmlatka nezadovolјavajući. Optimalan sklop za uspešno podmlađivanje bukve je od 0,6-0,7. Ukoliko je sklop veći, spontavno pojavlјen podmladak izumire, a ukoliko je ispod optimalnih vrednosti dolazi do zakorovlјavanja.
Abstract: Natural regeneration of beech forests has been studied in eleven high beech stands in Serbia. The stands are very heterogeneous and predominantly uneven-aged in terms of structure, owing to which group-shelterwood felling was recommended as a means of regeneration. The regeneration process is unmethodical, while the number and quality of young growth are unsatisfactory. The optimum canopy closure for a successful beech regeneration is from 0.6 to 0.7. If canopy closure is higher, a spontaneously occurred young growth will die out, while in case it is lower than the optimum value, weed infestation occurs.
