Abstract
Leta 1991 je vetrolom prizadel 16,5 ha pretežno listnatih gozdov v Žagarjevem grabnu, GGE Notranji Bohinj, leta 1996 pa je žledolom prizadel še 2,6 ha teh gozdov. V tem območju smo izločili štiri objekte glede na način obnove ter opravljeno nego. Znotraj objektov smo skupno zakoličili 101 ploskev (10 x 10 m). Popisana so bila vsa drevesa, višja od 20 cm, ter ocenjeno njihovo zastiranje po višinskih razredih ter drevesnih vrstah. Za vsako ploskev smo popisali tudi splošne orografske značilnosti ter oddaljenost od gozdnega roba. Namen raziskave je primerjati uspešnost naravne in umetne obnove ter analizirati povezanost gostote mladovja in orografskih dejavnikov ter zastiranja. Pri analizi podatkov smo uporabili Kruskal-Wallisov test in Spearmanovo korelacijo. Pri naravno obnovljenih objektih je prevladovala bukev (4816 dreves/ha in 2929 dreves/ha), v umetno obnovljenih objektih sta prevladovali smreka (2971 dreves/ha) in iva (2960 dreves/ha), bukev je bila na drugem mestu (2044 dreves/ha in 2862 dreves/ha). Bukev je zastirala največ površine z izjemo enega objekta, kjer je več zastirala iva. Ugotovili smo različne vplive orografskih dejavnikov, zastiranja in oddaljenosti od gozdnega roba na gostote. Ti vplivi so se razlikovali glede na posamezne drevesne vrste in objekte. Ker se pričakuje vse več izjemnih vremenskih dogodkov, smo na podlagi rezultatov podali usmeritve za prihodnje gospodarjenje z gozdovi.

Title:Natural and artifical regeneration of forest stands damaged by the storms in regional unit Bled
Abstract:
Windthrow damaged 16.5 ha of deciduous forests in Žagar's gorge (Žagarjev graben), GGE Notranji Bohinj, in 1991. In 1996, sleet damaged another 2.6 ha of these forests. We have presented four facilities according to the renovation process and the care done. We have marked out 101 surfaces (10 x 10 m) altogether. We have registered all trees higher than 20 cm and evaluated their veiling according to the altitude class and tree species. We have also registered general orographic features and distance from the forest edge for every surface. The purpose of the research has been to compare successfulness of natural and artificial renovation and to analyse dependence of young trees density from orographic factors and veiling. We have used Kruskal-Wallis test and Spearman correlation for the data analysis. At naturally renovated facilities, a beech tree predominated (4816 trees/ha in 2929 trees/ha), in artificially renovated facilities, spruce (2971 / treesha) and goat willow (2960 trees/ha), beech tree was on the second place (2044 trees/ha in 2862 trees/ha). Beech tree has been veiling the most of the surface except one facility where pussy willow was more successful. We have discovered different influences of orographic factors, veiling and distance from the forest edge to density. These influences have been different according to individual tree species and facilities. Several exceptional weather events are expected, therefore, we have suggested some guidelines for managing forests in the future.
