Naravna in umetna obnova v ujmah poškodovanih gozdnih sestojev v Območni enoti Bled : magistrsko delo - 2. stopnja = Natural and artifical regeneration of forest stands damaged by the storms in regional unit Bled : M. Sc. Thesis - master study programmesMedja, UrošLeta 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.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [U.
