Abstract:Varovalni gozdovi imajo pomembno vlogo pri zmanjševanju učinka različnih naravnih nevarnosti. Kljub pove- čevanju potreb po varovalni in zaščitni funkcij zaradi staranja gozdov in povečanega tveganja zaradi naravnih motenj ostaja aktivno upravljanje na nizki ravni. Proučili smo učinkovitost varovalnih gozdov za zaščito pred drobirskimi tokovi na severozahodu Slovenije, v Soteski med Bledom in Bohinjem, kjer sta zaradi delovanja pobočnih premikov ogroženi državna cesta in železnica. Na podlagi geološke karte in karte podvrženosti drobirskim tokovom smo ugotovili vplivno območje drobirskih tokov. Pri modeliranju njihovega širjenja smo uporabili program TopRunDF. Podatke o gozdu smo zbrali na 26 vzorčnih ploskvah, kjer smo izmerili vsa živa drevesa s prsnim premerom več kot 10 cm. Podrobno smo opisali sestoje in jih ovrednotili po metodi NaiS. Ugotovili smo, da ima gozd pomembno vlogo pri zaščiti infrastrukturnih objektov. Za uresničevanje trajnosti zaščitne vloge je treba enomerne sestoje prevzgojiti v mozaično enomerne. V sestojih, kjer gozdnogojitveni ukrepi ne zadostujejo, je treba uporabiti tehnične ukrepe. Ker s sestoji niso gospodarili več desetletij, so motnje (najpogosteje v obliki vetrolomov) pogoste. Izsledki kažejo, da je potrebno objektivno ovrednotenje varovalne in zaščitne funkcije takšnih gozdov. Priporočamo tudi aktivno nego, kar je v nasprotju z dosedanjo prakso v teh gozdovih.

Title:Assessment of forest protective function against debris-flows
Abstract:Protection forests play an important role of mitigating the influence of various natural hazards. Despite the growing need for protective functions due to aging forests and increased risk of natural disturbances, active forest management has become increasingly uncommon. Study of protection efficiency against debris flow of beech dominated forests in the Soteska gorge in NW Slovenia, where a main state road and railway are endangered was done. We assessed the starting points of the debris flow natural hazard based on a small-scale geological survey of the terrain characteristics and local debris flow susceptibility map. For determination of the run-out zones, we used the TopRunDF model. Forest structure data was obtained from 26 sample plots where all trees with DBH % 10 cm were measured. A detailed description and delineation of forest stands following NaiS methodology was performed. Results showed that the forests stands play a crucial role in protection of infrastructural objects. For long-term protection efficiency, introduction of spatial-variable regeneration patches is needed in uniform forest stands. In areas where silvicultural measures could not provide sufficient protection, technical measures are needed. Since these forests have not been managed for several decades, natural disturbances are frequent. Research findings suggest that assessment and management of these beech dominated protection forests is necessary, contrary to the current practice of non-management in protection forests in Slovenia.
