Razvoj planinskega smrekovega gozda v dolini Lopučnice v obdobju 1983-2022 [Elektronski vir] : magistrsko delo - 2. stopnja = Development of mountain spruce forest in Lopučnica Valley from 1983-2022 : M. Sc. Thesis - master study programmesPuhek, AidaPlaninski smrekov gozd v dolini Lopučnice se nahaja v Triglavskem narodnem parku in je del gozdnega rezervata Savica-Ukanc. Po leta 1883 opuščenemu gospodarjenju je prepuščen naravnemu razvoju. V ... dolini Lopučnice smo po 39 letih od prve meritve (Cvenkel in Mlinšek, 1983) in 24 letih od druge meritve (Poljanec, 1998) ponovili meritve na trajni raziskovalni ploskvi, ki jo je Cvenkel leta 1983 postavil kot del raziskav gozdnih rezervatov v Sloveniji. Namen naloge je bil predstaviti spremembe v zgradbi in razvoju planinskega smrekovega gozda v obdobju 1983–2022. Raziskovali smo spreminjanje velikosti vrasti in smrtnosti v obdobjih 1983–1998 in 1998–2022. Drevesna sestava je v proučevanem obdobju ostala nespremenjena. Osnovni kazalci sestoja za leto 2022 so imeli naslednje vrednosti: N = 388 dreves/ha, G = 57,60 m2/ha, V = 675 m3/ha. Skupna letna smrtnost se je v obdobju med letoma 1983 in 1998 iz 1,3 %/leto povišala na 1,5 %/leto za obdobje med letoma 1998 in 2022. Letne stopnje smrtnosti za obe opazovani obdobji so imele podoben vzorec, pri čemer so bile najvišje vrednosti v prvem debelinskem razredu. Skupna letna vrast 0,06 %/leto v obdobju med letoma 1983–2022 se je znižala na 0,04 %/leto v obdobju med letoma 1998–2022. Stopnja preraščanja med debelinskimi razredi za oba proučevana obdobja je bila najvišja v četrtem debelinskem razredu, najmanjša pa v prvem debelinskem razredu. V opazovanem obdobju (1983–2022) je prišlo do upada števila dreves, neznačilnih sprememb vrednosti temeljnice in manjše spremembe v lesni zalogi. Ta vzorec potrjuje, da se gozd še vedno nahaja v optimalni fazi, vendar je primerjava porazdelitve dreves po debelinskih razredih pokazala na postopno staranje sestoja.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
