20.500.12556/DiRROS-11356 The influence of abiotic and biotic disturbances on the protective effect of alpine forests against avalanches and rockfalls Vpliv abiotskih in biotskih motenj na varovalni učinek alpskih gozdov pred snežnimi plazovi in skalnimi podori Abiotic and biotic disturbances in alpine forests can reduce forest cover or change the structure of the forest and consequently reduce the protective effect of forest against natural hazards such as avalanches and rockfalls. In this review article, the effect of the main abiotic (forest fire, windthrow, ice break, snow break, avalanche and rockfall) and biotic (insects and pathogens) disturbances in protection forests are presented along with their potential influence on the protective effect of forest against avalanches and rockfalls. In general, natural disturbances negatively affect the protective effect of forest, especially in the case of large-scale and severe events, which in alpine areas are mostly caused by storms, bark beetle outbreaks, avalanches and forest fires. Climate change induced interactions between disturbances are expected to present challenges in the management of protection forests in the future. V gozdovih alpskega prostora lahko abiotske in biotske motnje vplivajo na porazdelitev in strukturo gozdov do te mere, da jim zmanjšajo varovalni učinek pred naravnimi nevarnostnimi, kot so snežni plazovi in skalni podori. V članku je zato predstavljen pregled glavnih vplivov abiotskih (gozdni požari, vetrolom, snegolom, žled, snežni plazovi in skalni podori) in biotskih (insekti in patogeni) motenj na varovalno in zaščitno funkcijo gozdov pred snežnimi plazovi in skalnimi podori. Naravne motnje na splošno negativno vplivajo na varovalni učinek gozda pred naravnimi nevarnostmi, še posebej v primeru veliko-površinskih dogodkov z visoko jakostjo poškodovanosti. Slednje so v alpskem prostoru najpogosteje posledica neviht, napada podlubnikov, snežnih plazov in gozdnih požarov. Podnebne spremembe in njihov vpliv na naravne motnje bodo v bodoče postale pomemben izziv pri upravljanju z gozdovi, ki opravljajo varovalno in zaščitno funkcijo. natural disturbances natural hazards abiotic disturbances biotic disturbances protection forests protective effect stand parameters rockfall avalanche naravna motnja naravne nevarnosti varovalna funkcija gozda varovalni učinek sestojni parametri skalni podori snežni plazovi zaščitna funkcija gozda true false true Angleški jezik Angleški jezik Neznano 2020-04-01 21:43:59 2020-04-01 21:44:01 2022-08-17 03:34:49 0000-00-00 00:00:00 2020 0 0 Besedilo v angl.; str. 1-18 Vol. 121 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*9:630*38:630*42(045)=163.6 2335-3112 10.20315/ASetL.121.1 5652134 266761216 RAZ_Oven_Domen_i2020.pdf RAZ_Oven_Domen_i2020.pdf 1 1F54B52BB6D89396E6B208CBB618515C a61768f1ee9d392ef41efde107c233b6fb49532ebf1f969f112b529bc7fb1e73 00c0bb79-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=13527 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
