Abstract
Cesto na Vršič ogrožajo snežni plazovi, gozdovi nad njo pa opravljajo zaščitno in varovalno funkcijo pred njimi. Analizirali smo potencialno ogroženost dela ceste in gozda nad njo, opravili presojo zaščitne funkcije gozda pred snežnimi plazovi ter določili smernice in ukrepe za nadaljnji razvoj gozda in krepitev njegovega varovalnega učinka. Na objekt raziskave smo postavili mrežo 21 raziskovalnih ploskev. Po modificirani metodi NaiS (Frehner in sod., 2005) smo izločili in opisali sestoje ter primerjali njihovo dejansko stanje s ciljnim, ki zagotavlja zaščito pred snežnimi plazovi. Glede na naklon in pokritost z gozdom smo naredili karto, ki kaže najbolj ogrožena območja pred snežnimi plazovi. Ugotovili smo, da noben sestoj ne zagotavlja popolne in trajne zaščitne funkcije. Največji problem sta pomlajevanje in zagotavljanje raznomerne strukture sestojev. Najpomembnejše smernice za nadaljnji razvoj gozda so pospeševanje raznomerne in raznodobne strukture, zagotavljanje pomladka, vzgoja čim večjega števila nosilcev stabilnosti ter zagotavljanje dobre vitalnosti in zadostne gostote dreves.

Title:Assessing the forest's protective effect against avalanches : the case of Russian road below Vršič
Abstract:
The road leading to the Vršič Pass is threatened by snow avalanches, and the forests above it are performing a protective function against them. We analysed potential hazard to the road and forests above it from snow avalanches, and evaluated the protective function of the forest. We defined guidelines and measures for further development of the forest to enhance its protective effect, and evaluated the actual spatial distribution of formalized protective function area of the forest within management plans. We set a network of 21 research sample plots. Using the modified method NaiS (Frehner et al., 2005), we defined the stand boundaries, analysed them and compared the actual state of the stands to the target situation. With regard to the slope and forest cover, we made a map of the sections most prone to formation of snow avalanches. We concluded that none of the stands provided complete and permanent protective function against snow avalanches. The greatest problems lay in poor regeneration and lack of unevenaged stand structure. The most important guidelines for the future development of the forest are favouring heterogeneous stand structure and regeneration, safeguarding good stability and vitality of the trees and providing for their sufficient density.

Keywords:protective forest, protective forest function, snow avalanche, management of protective forests, guidelines for forest management, silviculture of protective forest
