Abstract

V diplomskem delu smo ugotavljali, kako se visoki pajesen pomlajuje v ohranjenih gozdovih. Zanimalo nas je, kako okoljski dejavniki in druge drevesne vrste vplivajo na pomlajevanje visokega pajesena. V ta namen smo na vsaki lokaciji postavili v bližini semenskih dreves visokega pajesena dva transekta, ki smo ju vlekli v notranjost gozda. Na vsakem transektu je bilo 6 ploskev velikosti 5 x 5 metrov. Rezultati kažejo, da se visoki pajesen zelo dobro pomlajuje ob večjem deležu svetlobe in v bližini semenskih dreves. Pokazalo se je tudi, da visoki pajesen hitro preraste avtohtone drevesne vrste in zasede zgornje socialne položaje ter s tem vpliva na manjši delež avtohtonih vrst. Edina vrsta, ki mu uspe konkurirati, je robinija. Za omejitev širjenja visokega pajesena moramo v prihodnje več pozornosti nameniti gozdnogojitvenim ukrepom, ki so že del obstoječega gospodarjenja z gozdovi. Tak primer je npr. malopovršinsko gospodarjenje pod zastorom matičnega sestoja ter izvedba negovalnih ukrepov, ki zagotavljajo čim boljšo stabilnost in odpornost sestojev proti naravnim ujmam.

Secondary title: Regeneration ecology of tree of heaven (Ailanthus altissima (Mill.) Swingle) in managed forest in Goriško region
Secondary abstract: In the thesis, we tried to find out how successful is Ailanthus altissima regeneration in managed forests. We were interested in how environmental factors and other tree species affect the regeneration of the mentioned species. For this purpose, we set up two transects at the locations in the vicinity of the seed trees of Ailanthus altissima, which were positioned into the interior of the forest. On each transect 6 plots of size 5 x 5 m were established. The results show that Ailanthus altissima rejuvenates very well with greater proportion of light and near the seed trees. It was also shown that this tree quickly outgrows the native species and occupies the upper social positions and with this decreases the proportion of indigenous tree species. The only tree species that manages to compete with it is the black locust. To limit the spread of Ailanthus altissima in the future, we should pay more attention to the silviculture measures that are already part of the existing forest management. As an example; small surface management under the canopy of the parent stand, and implementation of nursing actions that ensure the best possible stability and resistance of stands to natural disasters.In the thesis, we tried to find out how successful is Ailanthus altissima regeneration in managed forests.
