Povzetek

V magistrski nalogi smo preučevali vpliv dveh tehnologij sečnje in spravila na pomlajevanje raznomernih mešanih sestojev. Raziskave so potekale na OE Novo mesto, v GGE Poljane, v oddelku 43. Namen naloge je preučevanje sprememb v strukturi, svetlobnih razmerah, zmesi in poškodovanosti mladja devet let po sečnji med dvema tehnologijama dela (prilagojena strojna sečnja in klasična sečnja). Po snemanjih iz leta 2009 in 2015 so bile opravljene dodatne terenske meritve izbranih znakov pomladka leta 2018. Ugotovitve kažejo, da pri poškodovanosti in razvoju mladja ni bistvenih razlik med prilagojeno strojno sečnjo in klasično sečnjo. Pri obeh načinih dela se je izkazalo, da so gostote mladja skozi vsa leta še vedno visoke, stopnja poškodovanosti osebkov in razlike med obema načinoma dela so se z razvojem mladja zmanjšale. Analize razvojnih gibanj in višinske strukture mladja kažejo, da skozi vsa leta z višino izrazito narašča delež bukve, zaradi pospešene obnove, pa obstaja tudi velik potencial za manjšinske drevesne vrste. Ugotovljeno je bilo, da se je zmes od leta 2009 do 2018 spremenila v želeno smer z manjšim deležem smreke, vendar, zaradi objedanja divjadi in ekstenzivne nege sestojev, analize kažejo na neuspešno preraščanje gorskega javorja in jelke.

Sekundarni naslov: Impact of two timber harvesting Technologies on regeneration of uneven-aged silver fir-beech stands
Sekundarni povzetek: In the master's thesis, we studied the influence of two methods of logging on regeneration in uneven-aged mixed mountain stands. The research was conducted in the Novo mesto forest management region, Poljane forest management unit, compartment 43. The purpose of the thesis was to analyze the changes in light conditions, regeneration structure, mixture and damage following two working methods (combined machine logging and motor-manual cutting). After the recordings in the years 2009 and 2015, additional field measurements of the selected parameters of regeneration were performed in 2018. The findings show that there were no essential differences between two working methods regarding damage and development of regeneration. In both treatments the density of regeneration remained high during the whole inventory period. The level of damage of to individual saplings and the differences between both treatments declined with the development of regeneration. The analysis of development and height structure of regeneration showed, that the share of beech distinctively increases. Because of swift removal of mature stand, a good potential for minority tree species was recorded. It was ascertained that the mixture changed into the desired direction from the years 2009 to 2018 with a declining share of spruce when compared to the mature stand. However, the analyses indicated unsatisfactory recruitment of sycamore maple and silver fir because of overbrowsing by ungulates and the lack of frequent tending of crop trees.
