Abstract
Zaraščanje brežin gozdnih cest je odvisno od več dejavnikov. V nalogi smo pregledali in izmerili 240 prečnih profilov gozdnih cest in ocenili zaraščenost brežin le teh na območjih Menine planine in Kamniške Bistrice. Omejili smo se le na trdo podlago, t.j. 5 kategorijo hribine. Nezaraščene brežine pomenijo grožnjo za varnost v prometu, kvarijo estetsko podobo krajinein so potencialno erozijsko žarišče. Na zaraščanje brežin vplivajo naklon brežine, širina svetlega profila nad cesto in tla. Nasipne brežine se zaraščajo bolje od odkopnih, saj so v povprečju bolj položne in tudi zgrajene na način, ki omogoča hitrejše zaraščanje: zdrobljena matična podlaga spodaj, po vrhu pa posuta prst, ki jo dobimo pri odkopu. Brežine na toplih legah (J, Z) se zaraščajo uspešneje kot brežine na hladnih legah (S, V), ravno tako se brežine, kjer je dovolj svetlobe, zaraščajo uspešneje. Tako smo ugotovili, da sta ključna dejavnika pri zaraščanju brežin gozdnih cest ekspozicija, svetlobain naklon brežine ter z tem povezana količina organske snovi na brežini.

Abstract:
Revegetation of the forest road side slopes depends on several factors. In theses we reviewed and measured 240 transverse profiles of forest roads and assessed side slope revegetation in Menina highland and Kamniška Bistrica. Werestricted our research to solid grounds, that is a fifth slope category. Unrevegetated side slopes are threat to the traffic security, they spoil easthetic image of a countryside and are a potential erosion focal point. Influence on the side slope revegetation have inclination of the side slope, width of a light color profile and nevertheless the ground. Causeway side slopes are revegetating better than excavated side slopes, because they have on average lower inclination and are built in the way that ensures faster revegetation: granulated original foundation beneath, on top is strewed earth,which is produced by excavation. Side slopes on warm sites (S,W) are revegetating better than side slopes on cold azimuths (N, E), at the same time side slopes which get enough light revegetate more successfully. We concluded, that main factors for the forest side slopes revegetation are azimuth, a light, a slope inclination with connection to the amount of organic substance in the side slope.
