Vpliv sečnje in spravila na razvoj vegetacije vetrolomnih površin : diplomsko delo - visokošolski strokovni študij - 1. stopnja

Na treh lokacijah mešanega bukovega gozda smo postavili raziskovalne ploskve v velikosti 100 m2, na katerih smo preučevali pomlajevanje gozda po ujmi. Ploskve so bile zakoličene na območju Črmošnjic, ki je bilo v letih 1983 in 2006 podvrženo žledolomu, in na območju Zadloga in Nemškarice, kjer je leta 2006 prišlo do vetroloma. Kot spravilno sredstvo so na vseh treh območjih uporabili žičnico. Ploskve, na katerih se je popisovalo drevesne vrste, višinski razred, objedenost, poškodovanost, prirastek in mikrorastišče, so bile enakomerno razdeljene na saniranem in nesaniranem področju. Na ploskvah, kjer je bila opravljena sanacija, je bilo popisanih 43.200 osebkov/ha, na ploskvah brez ukrepanja pa 50.380 osebkov/ha. V mladju je prevladovala bukev s primesjo gorskega javorja, velikega jesena in črnega gabra. Delež objedenega mladja je bilo s 14.333 osebki/ha (33 %) na saniranih ploskvah manjše v primerjavi s 27.466 osebki/ha (55 %) na nesaniranih ploskvah. Erozija je bila veliko močnejša na saniranih delih in je na nekaterih ploskvah pokrivala 90 % površine.

Abstract

Research plots were established on three different locations of mixed beech forest which formed the basis of assesing forest regeneration following natural disturbance. Plots were formed around area of Črmošnjice, which was affected by icestorm in 1983 and 2006 and the area of Zadlog in Nemškarica which were affected by windthrow in 2006. Logging was carried out by cable crane on all three areas. Plots were evenly distributed on both logged and unlogged areas and were used for comparing browsing demage, tree diversity and density, seedling growth and microsites. On logged areas there were 43.200 specimens per ha compared to 50.380 specimens per ha on unlogged areas. Seedling were composed mostly of beech with admixture of sycamore, ash and european hop-hornbeam. Browsing demage was less severe on logged plots with 14.333 browsed specimens per ha (33 %), while 27.466 specimens per ha (55 %) were browsed on unlogged plots. The erosion was more intense on logged plots and was affecting 90 % of the area on some plots.
