Razvoj in rast mešanega jelovo-bukovo-smrekovega prebiralnega gozda Volčji štant na Borovški gori [Elektronski vir] : magistrsko delo - 2. stopnja = Growth and development of mixed fir-beech-spruce single-tree selection forest Volčji štant on the Borovška gora Mountain : M. Sc. Thesis - master study programmesJovanovič, LejaV raziskovalnem objektu Volčji štant na Borovški gori smo preučili razvoj in rast mešanega jelovo-bukovo-smrekovega gozda. Najprej smo izvedli ponovne terenske meritve objekta, kjer smo na 45 ... 5-arskih krožnih ploskvah popisali izbrane parametre dreves. Sledila je obdelava podatkov, v kateri smo analizirali sestojne parametre, rast dreves in sestojev ter primerjali ukrepanje v letih 2007 in 2022. Kljub stalnemu spreminjanju gozdnega ekosistema in 15-letni odsotnosti aktivnega ukrepanja, je bila prebiralna zgradba leta 2022 še vedno ohranjena, vendar v primerjavi z letom 2007 nekoliko spremenjena. Lesna zaloga se je v tem obdobju povečala za približno 10 %, povečal se je delež debelega drevja. V lesni zalogi je največji delež predstavljala jelka (67 %), sledile so bukev (17 %), smreka (15 %) in ostale drevesne vrste (1 %). V tem obdobju se je povečal delež jelke (za 28 %) in smreke (za 20 %), zmanjšal pa delež bukve (za 31 %). Kljub dokaj uravnoteženi zgradbi prebiralnega gozda, je bila vrast dreves nizka in blizu kritične mejne vrednosti. Povprečni debelinski prirastek dreves je znašal 0,31 cm/leto, medtem ko je bil povprečni volumenski prirastek 0,04 m3/leto. Iglavci so imeli višje prirastke kot listavci. Leta 2007 je jakost poseka predstavljala 21 % lesne zaloge, leta 2022 pa le 11 % (volumen odkazanih dreves je bil 136 m3). V poseku 2007 in odkazilu 2022 je prevladovala bukev. Glede na naše rezultate bi morali povečati jakost poseka in zagotavljati uspešno vrast jelke, saj se bo le na takšen način tudi v bodoče ohranjala prebiralna struktura sestojev.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
