Abstract

V diplomski nalogi je analiziran vpliv mezoreliefa na objedanje mladja po velikih rastlinojedih parkljarjih. Rastlinojeda parkljasta divjad je naravni sestavni del gozdnega ekosistema. Med ostalim se prehranjuje tudi z mladimi drevesi in jih s tem lahko uniči ali poškoduje. Poškodovanost mladja drevesnih vrst smo merili na 238 ploskvah v GGE Mirna gora. Največjo stopnjo objedanja smo izmerili na grebenu 100 % in v vrtačah z prisojnim delom vrtač 82 %, na platoju 79 %, najmanjšo stopnjo objedanja smo izmerili na ravnem in na pobočju 70 %. Najbolj objedena drevesna vrsta je bil javor. Največ mladja vseh drevesnih vrst bilo objedenega v višinskem razredu 21-50 cm (76 %). Ugotovili smo povezanost med skalovitostjo in objedanjem mladja. Z večanjem skalovitosti se je večala stopnja objedenosti mladja vseh drevesnih vrst. Z večanjem razdalje do kritja (mladje do višine 5 m) se je znižala stopnja objedenosti jelke.

Secondary title:	The influence of meso-relief on browsing damage caused by large herbivores
Secondary abstract:	The thesis analyzed the impact of meso-relief on browsing of seedlings by large herbivores. Herbivore hoofed game is a natural part of the forest ecosystem. Because of herbivorous ungulates that feed on plant parts are consequently damaged also young trees. We studied the browsing damage on the total of two hundred and thirty eight plots at the location site in GGE Mirna gora. The highest level of browsing damage was measured at the ridges of 100 % and 82 % in sinkholes with sunny part of sinkholes, in the plateau 79 %, the lowest level of browsing damage vas measured on slope and on flat 70 %. Most heavily damaged species was sycamore maple. Most individuals of any seedlings together were damaged within the height class 21 to 50 cm (76%). We found statistical association between rockyness and damaged seedlings. By the increasing rockyness the damage rate of all tree species increased. By increasing the distance to cover (seedlings to 5 m height) is the damage rate of fir decreased.
