Razvoj gozdov v gozdnogospodarski enoti Leskova dolina : diplomsko delo - univerzitetni študij = Forest development in the Leskova dolina forest management unit : graduation thesis - university studiesKogovšek, TadejAvtor je analiziral razvoj gozdov na ravni oddelkov v gozdnogospodarski enoti Leskova dolina od leta 1912 do danes. Primerjal je podatke iz načrtov za osem urejevalnih obdobij z začetkom veljavnosti ... leta 1912, 1936, 1954, 1964, 1974, 1984, 1994 in 2004. Po oddelkih je spremljal razvoj lesne zaloge, razmerje mediglavci in listavci, spremembo prirastka, debelinske strukture in sečnje. Vdveh oddelkih je analiziral starost posekanih dreves. Lesna zaloga je v preučevanem obdobju stalno naraščala. Delež iglavcev v lesni zalogi je do leta1936 naraščal, v obdobju do leta 1974 je variiral, potem je začel upadati.Delež jelke se je po letu 1974 stalno zmanjševal, povečeval pa se je delež bukve in smreke. V letu 2004 je delež listavcev dosegel 30 % celotne lesne zaloge. Na krepitev listavcev v lesni zalogi je vplivalo opuščanje prebiralnega načina gospodarjenja in slabša vitalnost jelke. Spremembe prirastka so bile v tesni korelaciji s spremembo lesne zaloge. Prirastek iglavcev je bil v preučevanem obdobju vseskozi večji od prirastka listavcev. Debelinska struktura se je v preučevanem obdobju 92 let spremenila. V letu 1912 je bila večina lesne zaloge v debelinskih razredih A (10-30 cm) in B (30-50 cm). V analiziranem obdobju se je delež lesne zaloge v razredu C povečal. Sečnja je bila v preteklosti odvisna od socialnega in gospodarskega položaja ljudi, po letu 1974 se je ustalila. Analiza starosti dreves je pokazala, da so se dominantne jelke pomladile v obdobju 1836-1842, smreke pa vobdobju med letoma 1831 in 1849.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
