Povzetek

aravne nesreče so zadnja desetletja vse bolj pogoste. V raziskovalni nalogi smo se osredotočili na površine prizadete zaradi vetroloma leta 2017 v Gozdnogospodarskem območju Slovenj Gradec. Želeli smo ugotovili, kakšno sposobnost naravne obnove ima gozd po tovrstnih ujmah. Podatke smo pridobivali v dveh stratumih gozdov. Enega so pred ujmo pokrivali čisti smrekovi sestoji, drugega pa mešani bukovi sestoji. V vsakem stratumu smo postavili 12 ploskev, velikih 10 x 10 m. Ugotovili smo, da v obeh stratumih na raziskovalnih ploskvah prevladuje zastiranje zeliščne plasti. Med stratuma smo ugotovili razlike, in sicer v bukovem stratumu je bilo z 11.117 osebki/ha več mladja kot v smrekovem stratumu s 6292 osebki/ha. Bukov stratum je imel bolj ugodno višinsko strukturo in drevesno sestavo z manjšim deležem problematične smreke in velikega jesena. Čeprav smo tudi na smrekovih rastiščih zabeležili nekatere ugodne znake, kot so manjši delež zastiranja talne vegetacije in večja raznolikost drevesnih vrst, ima smrekov stratum slabše možnosti za nemoten razvoj v primerjavi z bukovim stratumom.

Sekundarni naslov: Comparison of post disturbance regeneration in spruce and mixed beech forest stands following severe windthrow
Sekundarni povzetek: Natural disturbances have become more common in recent decades. In this research, we focused on the areas affected by the 2017 windstorm. We wanted to find out the resilience capacity of the forest after such disturbances. The data was obtained in two areas, that were before the windstorm covered by pure spruce stands and mixed beech stands. In each area 12 plots were placed, 10 x 10 m in size. We found out that in both areas research plots are predominantly covered by the herbaceous vegetation. We found significant differences in regeneration density between the areas. In the beech area the total regeneration density was 11.117 per ha, which was more compared to the spruce area with the regeneration density of 6292 per ha. Beech area also had a more favorable height structure and tree composition with a smaller proportion of problematic Norway spruce and common ash. Although some favorable indices have also been recorded in spruce area, such as a lower proportion of ground vegetation and greater tree diversity, the spruce area nevertheless shows smaller capacity to recover compared to the beech one.
