Abstract

V goratih območjih je padajoče kamenje naraven proces, vendar lahko zaradi svojega spontanega sprožanja in izjemnih hitrosti povzroča nevarnost za prometne ceste in naselja. Na strmem pobočju nad vršiško cesto so številni izvori kamenja, ki ogrožajo pomembno prometno povezavo med Kranjsko Goro in Bovcem, kot tudi vse uporabnike te regionalne ceste. Presodili smo varovalno funkcijo gozdov pred padajočim kamenjem nad delom ceste na kranjskogorski strani v bližini ruskega križa. Izločili in popisali smo sestoje ter jih ovrednotili po metodi NaiS. Dejansko stanje smo primerjali s ciljnim stanjem, ki zagotavlja trajno zaščito pred padajočim kamenjem. Podatke smo analizirali s programom Excel in ugotovili, da znaša delež bukve v lesni zalogi 54 %, delež smreke 26 % in delež macesna 20 %. Porazdelitev dreves po debelinskih stopnjah nakazuje na premajhen delež dreves v tretji debelinski stopnji in premajhen delež bukve v višjih debelinskih razredih. Za trajno zaščitno funkcijo je potrebno z gozdovi gospodariti raznomerno in raznodobno ter zagotavljati pomlajevanje. Kjer gozdnogojitveni ukrepi ne zadostujejo, je potrebno uporabiti tudi tehnične ukrepe. Priporočamo načrtno gospodarjenje z varovalnimi gozdovi, ki vključuje aktivno nego za zagotavljanje trajne zaščitne funkcije.

Secondary title:	Assessment of protective effect of forest against rock falls above Vršič pass road
Secondary abstract:	In mountain areas, rockfall is a natural process, nevertheless it can present a risk for transportation routes and nearby villages due to its spontaneous release and extreme velocities. On steep slope above the Vršič pass road, there are many rockfall sources that threaten not only an important transportation connection between Kranjska gora and Bovec but also all users of this regional road. An assessment of protection function of the forest against rockfall above a part of the road has been made. We specified the stand boundaries and evaluated them by the NaiS method. Current state has been compared to the target state that provides protection against rockfall. Data were analyzed using Excel program and we determined the proportion of total wood stock of beech 54%, of spruce 26% and of larch 20%. Frequency distribution of tree species indicated insufficient portion of trees in the third dbh class and lack of large beech trees. In order to provide a long-term protection efficiency, both multi-aged forest management and regeneration are necessary. In areas where silvicultural measures do not suffice, an introduction of technical measures is need. We recommend planned management of protection forests, including active care to provide protective role in a sustained way.
