Ekologija pomlajevanja robinije(Robinia pseudoacacia) v gospodarskih gozdovih na Dolenjskem

Povše, Špela (author), Roženbergar, Dušan (mentor), Nagel, Thomas Andrew (co-mentor)

Robinija spada med najinvazivnejše tujerodne drevesne vrste v Sloveniji in Evropi. V diplomski nalogi smo predstavili robinijo na Dolenjskem. Na treh raziskovalnih ploskvah v gospodarskih gozdovih, ki smo jih postavili v občini Sevnica, smo analizirali pomlajevanje in ugotovili, kakšna je invazivnost oz. razširjenost robinije, še posebej v plasti mladja. Ugotovili smo, da se robinija najintenzivnejše širi na območja, kjer so se zaradi ujm odprli sestoji. Na območjih, kjer prevladujejo starejši osebki, pa robinije skorajda ne zasledimo. Zaradi prisotnosti semenskih dreves smo robinijo zasledili tudi na razdalji, daljši od 60 metrov od matičnega sestoja. V gozdnogospodarskih gozdovih na Dolenjskem nismo opazili, da bi robinija lahko gradila čiste sestoje. Z ustreznimi gojitvenimi ukrepi bi se robinijo dalo nadzorovati, kar pa je v državnih gozdovih veliko bolj izvedljivo kot pri zasebnih lastnikih gozdov.

• Title: REGENERATION ECOLOGY OF BLACK LOCUST (Robinia pseudoacacia L.) IN THE DOLENJSKA REGION MANAGED FORESTS

Abstract

Robinia is one of the most invasive alien tree species in Slovenia and Europe. The diploma thesis is presenting robinia in Dolenjska region.Three areas in the municipality of Sevnica were explored, thus presenting how invasive and spread the species is. We analysed the regeneration of robinia in commercial forests in the Dolenjska region. We have come to the conclusion that robinia is most intensively expanding to areas where canopy was removed due to the natural disturbances. In areas where canopy is more closed, robinia was not present. Due to the presence of seed trees, robinia was also observed at a distance of more than 60 meters from the parent stand. In the managed forests of the Dolenjska region, no pure observed. Appropriate silvicultural measures would allow the robina to be controlled, which is far more feasible in state forests than in private forest.
