20.500.12556/RUL-173815 Naravno pomlajevanje na žičniških linijah Natural regeneration of forest stands following cable crane yarding Diplomsko delo vsebuje analizo naravnega pomlajevanja na dveh žičniških linijah na Ljubelju. Linije smo v vzdolžni smeri razdelili na tri dele in sicer na zgornjega, srednjega in spodnjega, v prečni smeri pa na zahodni, srednji ter vzhodni del. Na vsakem od teh delov smo postavili ploskve v velikosti 1,5 x 1,5 m v diagonalni smeri, znotraj katerih smo popisali pomlajevanje (gostoto in pokrovnost), določili kamnitost in skalovitost, ostanke dreves in določili ekspoziciji ter naklon. Namen te postavitve je bilo določiti ali prihaja o razlik v pomlajevanju med vzdolžnimi ter prečnimi deli tras. Ugotovili smo, da je bila spodnja trasa s ca. 3 osebki/m2 bolj pomlajena od zgornje z 0,9 osebki/m2. Na spodnji je prevladoval veliki jesen, na zgornji pa bukev. Na slednji so bili zahodni robovi s ca. 1,3 osebki/m2 bolj pomlajeni od vzhodnih. Na spodnji trasi pa je bil vzhodni rob bolj pomlajen od zahodnega, dobrimi 4,4 osebki/m2, kar je lahko posledica drugačnih drevesnih vrst v pomladku. Razlike so se pojavljale tudi glede na vzdolžne predele tras, predvsem zaradi konkurence zeliščne plasti. Rezultati nam lahko koristijo pri razumevanju dinamike pomlajevanja tras v povezavi z njihovim potekom ter razlik med vzdolžnimi ter prečnimi deli tras, ter zakaj do takih razlik prihaja. Vpogled v pomlajevanje nam lahko služi tudi kot pripomoček za odločanje o morebitni dopolnilni sadnji. The thesis contains an analysis of natural regeneration of target tree species (fir, spruce, beech, maple) on two cable crane lines. They have been devided for the purpose of the analysis on three longitudional sections (upper, middle and lowwer) and on three transverse section (west, middle an east). On each section we have placed a diagonal positioning of measuring plots 1,5 x 1,5 m in size. On each plot we measured the density and coverage of regeneration, estimated the coverage of stones and rocks as well as tree residuals. We also determined slope steepness and exsposition. The purpose of this plot arregement was to determine whether there were differences in regeneration between the longitudional and transverse parts of of the lines. We found that the lower line , with approx. 3 individuals/m2, was better regenerated than the upper line, with 0,9 individuals/m2. The lower line was dominated by common ash, while the upper line was dominated by beech. On the upper line, the western edges were more regenerated than the eastern edges, with approximately 1.3 individuals/m2. On the lower line, the eastern edges were more regenerated than the western edges, with 4.4 individuals/m2. The differences also apeared on the longitudional sections of the lines, manely due to the compettion of herbuos layer. The results can help us understand the dynamics of regeneration on the cable crane lines in relation to their direction and the differences between the longitudional and transverse parts of the lines. as well as why such differences occur. Insight into regeneration can also serve as and aid in diciding on possible supplementary planting. naravno pomlajevanje gorski gozd varovalni gozd zeliščna plast Ljubelj regeneration natural regeneration cable crane lines Ljubelj true false false [O.
