Primerjava situacijskega in izbiralnega prvega redčenja na Kočevskem [Elektronski vir] : magistrsko delo - 2. stopnja = Comparison of early selective thinning and situational thinning in the Kočevje region : M. Sc. Thesis - master study programmesLogar, Špela, gozdarstvoV nalogi smo primerjali dva načina prvega redčenja: klasično izbiralno in situacijsko redčenje. Zanimala nas je struktura konkurentov, razlike v stabilnosti ter katerim kriterijem pri izbiri dreves ... se pri izvajanju obeh načinov v praksi najbolj sledi. Raziskavo smo izvedli v revirju Vrbovec, GGO Kočevje, na rastišču podgorskih gradnovih bukovij na nadmorski višini od 520 m do 695 m. Objekt raziskave je bil razdeljen na osem 0,04 ha kvadratnih ploskev. Prve štiri ploskve so bile namenjene analizi situacijske nege, druge pa izbiralnemu redčenju. Med obema načinoma redčenja nismo ugotovili velikih razlik v količini izmerjene svetlobe po izvedenem ukrepu. Razlike so bile očitnejše, ko smo primerjali kandidate s konkurenti. V primeru situacijskega redčenja je bilo ukrepanje usmerjeno na plemenite listavce, nega poškodovanih dreves ni bila izvedena. Če primerjamo situacijsko nego z izbiralnim redčenjem, je bila jakost redčenja nižja, sproščanje ciljnih dreves pa je bilo intenzivnejše. Razlike med načinoma so se izkazale v kolektivnosti. Na ploskvah, kjer se je izvedla situacijska nega, je bila kolektivnost za drevesa v strehi sestoja bolj ohranjena. Če primerjamo povprečne vrednosti ocen kolektivnosti za izbrance oz. kandidate, so bile razmere pri situacijski negi ugodnejše, saj so imeli izbranci pri situacijski negi v povprečju bolj sproščene krošnje.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [Š.
