Nekateri ukrepi za omejevanje širjenja visokega pajesena (Ailanthus altissima (Mill.) Swingle) in smernice za gozdnogojitveno ukrepanje ob vdoru potencialno invazivnih tujerodnih drevesnih vrst v ohranjene gozdove v Sloveniji

Visoki pajesen je ena bolj razširjenih tujerodnih drevesnih vrst v Sloveniji. Najpogosteje se razrašča zunaj gozda, včasih pa ga najdemo tudi v gozdnem prostoru. V naših gozdovih je kemično zatiranje prepovedano, zato smo preizkusili tri vrste mehanskega zatiranja te vrste. Najuspešnejša metoda je bila puljenje celotnih osebkov, najmanj pa lomljenje enoletnih poganjkov. Mehansko zatiranje je najučinkovitejše, če ga kombiniramo z drugimi ukrepi, kot so: malopovršinsko pomlajevanje, skrb za polnilno plast, uporaba gozdnogojitvenih sistemov, ki pospešujejo vrstno in strukturno pestrost sestojev ter pospeševanje in sajenje hitrorastočih, rastišču primernih domorodnih vrst. The tree of heaven is one of the most widespread non-native tree species in Slovenia. In most areas, its spread occurs in non-forested areas, yet recent observations indicate it is becoming more common within some forest ecosystems as well. Because chemical treatment is banned in Slovenia, this study tested the effectiveness of three mechanical control treatments. Breakage of annual and biennial shoots was not successful the best treatment was total removal by pulling seedlings and saplings. Mechanical control of invasive tree species is more effective if combined with other management approaches, such as practicing silviculture that promotes vertically diverse stands of native tree and shrub species, particularly small-scale silviculture that maintains a subcanopy layer.
