Uspešnost naravnega pomladka na območjih prizadetih po ujmah = Performance of natural regeneration following natural disturbances : diplomsko delo - visokošolski strokovni študij : graduation thesis - higher professional studiesKvas, RokNa področju gozdnogospodarskega območja Tolmin smo postavili več raziskovalnih ploskev, na katerih smo preverjali uspešnost pomlajevanja gozda po ujmi. Prvi niz ploskev smo zakoličili na področju ... Jagršč, kjer je leta 2007 prišlo do vetroloma, dodatno pa je gozd poškodoval še snegolom. Drugi niz ploskev smo zakoličili v dolini reke Zale, kjer je leta 2005 vetrolom ustvaril številne vrzeli. V Jagrščah so za namene spravila zgradili novo gozdno prometnico, v dolini reke Zale pa so spravilo opravili z žičnico. Ploskve smo zakoličili tako na spravljenih kot nespravljenih področjih in primerjali gostoto in drevesno sestavo, objedenost mladja, mikrorastišča, erozijo in prirastek mladja. Ugotovili smo, da je bilo na ploskvah z ukrepanjem 34.200 osebkov na ha, na ploskvah brez ukrepanja pa 18.033 osebkov na ha. Med drevesnimi vrstami so prevladovali listavci - mali jesen, črni gaber, bukev in gorski javor. Skoraj polovico dreves na prizadetih območjih je spadalo v višinski razred med 21 in 50 cm. Objedanja je bilo veliko več na ploskvah z ukrepanjem, kjer je bilo objedenih 22.500 osebkov na hektar, na ploskavah brez ukrepanja pa je bilo objedenih 8.750 dreves na hektar. Mikrorastišče pri pomlajevanju ni igralo večje vloge, saj je večina dreves (96,8 %) rasla na navadnih gozdnih tleh. Višinsko priraščanje pomladka je bilo na ploskavah z ukrepanjem kar trikrat boljše kot na ploskvah, ki so bila prepuščena naravni obnovi.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
