Sanacije v ujmah poškodovanih gozdnih sestojev v območni enoti Tolmin : magistrsko delo - magistrski študij - 2. stopnja = Rehabilitation of stands after the storm in the tolmin area : M. Sc. Thesis - master study programmeŠkvarč, Jernej, gozdarNamen magistrskega dela je bil presoditi uspešnost sanacije na izbranih objektih in pripraviti usmeritve za podporo pri odločanju v prihodnje, saj pričakujemo večjo pogostost in jakost izjemnih ... vremenskih dogodkov. Na vetrolomni površini, ki je nastala julija 2008 je bilo postavljenih petnajst vzorčnih ploskev (10 m x 10 m) na naravno obnovljenih površinah in petnajst ploskev na umetno obnovljenih površinah, ki so bile posajene s navadno smreko in navadno bukvijo. Na ploskvah so bila izmerjena vsa dominantna drevesca in vse posajene sadike. Opravljen je bil tudi popis gostote in zastiranje naravnega pomladka ter zastiranje grmovne in zeliščne plasti. Gostota naravnega pomladka pri naravni obnovi je bila 8.000 drevesc/ha pri umetni obnovi pa 4.556 drevesc/ha. Zabeleţenih je bilo 8 različnih drevesnih vrst, med katerimi so prevladovale iva, navadna bukev, gorski javor in navadna jelka. Zeliščne in grmovne vrste so v povprečju zastirale 64 %, največje zastiranje je bilo zabeleţeno pri malinjaku. Gostota sadnje je znašala 2.765 sadik/ha. Uspeh sadnje je bil zelo dober, saj je bila mortaliteta tri leta po njej le 7 %. Zastiranje grmovne in zeliščne plasti ter malinjaka je negativno vplivalo na gostoto naravnega mladja. Rezultati raziskave so nakazali, da je bila umetna obnova uspešnejša od naravne obnove, ker pa je bistveno dražja se za umetno obnovo odločamo na najbolj rodovitnih rastiščih, erozijsko ogroženih površinah in tistih z bujno razvito pritalno vegetacijo in na površinah z majhnim številom semenskih dreves.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
