Analiza nasada tujerodnih drevesnih vrst na Boču [Elektronski vir] : magistrsko delo - 2. stopnja = Analysis of non-native tree species plantation on Boč : M. Sc. Thesis - master study programmesLesičar, MitjaNasadi tujerodnih drevesnih vrst (TDV) v Sloveniji so bili osnovani že konec 19. stoletja. V nasadu TDV v arboretumu na Boču najdemo 23 različnih TDV. Namen dela je bil celostno analizirati nasad. S ... polno premerbo smo analizirali zgornji sloj, popis mladja smo izvedli na 12-ih naključno postavljenih ploskvah v 4-ih stratumih, arboretum smo posneli z brezpilotnim letalnikom za natančnejše karte in naredili presojo gozdnogojitvenih ciljev in predlagali ukrepe. Ugotovili smo, da je lesna zaloga nasada 290,2 m3/ha, v njej prevladujejo TDV (63,6 %), čeprav je gostota avtohtonih vrst večja (55,9 %), kar pomeni, da so drevesa TDV v povprečju debelejša in višja. V mladju prevladujejo avtohtone vrste, saj najdemo 34.375 osebkov mladja na ha avtohtonih in 10.000 osebkov na ha TDV. Med TDV se pomlajujejo samo velika jelka, rdeči hrast, nav. ameriška duglazija, kavkaški krilati oreškar in kavkaška smreka. Vse se pomlajujejo v bližini in večinoma pod zastorom semenskih dreves. Na odprtih površinah niso konkurenčne domačim vrstam mladja ter bujnemu zeliščnemu in grmovnemu sloju. V presoji gozdnogojitvenih ciljev smo predlagali razglasitev nasada kot gozd s posebnim namenom z načrtovanim ukrepom (GPN), saj ima izredno poudarjeno poučno in raziskovalno funkcije. V njem bo potrebno adaptivno in aktivno upravljanje, če želimo ohraniti TDV, saj njihova reprodukcijska sposobnost ne zagotavlja obnavljanja populacije, ki bo potrebna zaradi slabše vitalnosti nekaterih TDV.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
