Vpliv redčenj na poškodovanost dreves po žledolomu leta 2014 na območju Slanic v okolici Idrije : diplomsko delo - univerzitetni študij - 1. stopnja = Effect of thinning on tree damage from the 2014 ice storm in the Idrija region : B. Sc. Thesis - academic study programmesGrahelj, PrimožFebruarski žledolom leta 2014 je na Idrijskem naredil ogromno škode. Da bi izvedeli še kaj več smo se podali na teren, kjer smo analizirali negovane in nenegovane sestoje in ugotavljali, ali redčenja ... v bukovih sestojih vplivajo na poškodbe dreves po žledu, ali pa je bila ujma tako neselektivna, da teh razlik ni bilo zaznati. Glede na negovanost smo v vsakem sestoju postavili 12 ploskev v velikosti 200 m2. Na terenu nas je najbolj zanimala stopnja poškodovanosti na izbranih ploskvah, ugotavljali pa smo tudi število mrtvih dreves in socialni položaj dreves ter še nekatere druge parametre. Ugotovili smo, da je v negovanih sestojih značilno manjše število dreves z močno poškodovanimi krošnjami. Razlike v pojavljanju drugih tipov poškodb v negovanih in nenegovanih sestojih niso bile značilne, kar kaže na to, da je bila ujma zelo močna in zato tudi delno neselektivna. Največ nepoškodovanih dreves je bilo med podstojnimi drevesi, največ močno poškodovanih pa med soraslimi drevesi. Nadrasla drevesa so imela najmanj močnih poškodb. Poškodovanost se je povečevala z večanjem naklona, vendar so bile razlike majhne in v našem primeru naklon ni bil najpomembnejši dejavnik, ki vpliva na poškodbe. Najbolj prizadeta drevesna vrsta je bila bukev, najmanj poškodb pa smo zabeležili za jelko.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana, 2018 : [P.
