Abstract

V luči klimatskih sprememb, vse pogostejših naravnih motenj in oteženih ekonomskih razmer se srečujemo z vprašanjem, kako z omejenimi sredstvi pravočasno negovati čim večje površine mladega gozda. V magistrskem delu smo si zastavili dva primarna cilja: s kvantitativnimi metodami oceniti uspešnost obnove gozdnih površin po vetrolomu in gradacijah podlubnikov ter izvesti primerjavo situacijske in tradicionalne nege z odkazilom na dveh ploskvah s starejšo razvojno fazo, poškodovanih po ujmah. Pri uporabi kvantitativnih metod smo ugotovili, da so se površine najbolj obnovile skladno s cilji ekološke sanacije, kar pomeni visok delež pionirskih in drugih gospodarsko manj pomembnih vrst. Metode bi potrebovale izboljšave, saj najverjetneje zaradi preveč konservativnih referenčnih vrednosti pri izračunih prikazujejo sliko obnove, ki se ne sklada nujno z dejanskim stanjem. Analizo starejših razvojnih faz po metodi strukturne in ekološke obnove s pomočjo celic smo zaradi njene preglednosti in preprostosti ocenili kot uporabno orodje za hitro ocenjevanje razvoja gozda po ujmah. Na obeh ploskvah smo imeli večji uspeh pri doseganju ciljev ekološke obnove kot pa strukturne. Obe ploskvi, kjer smo opravili primerjavo tradicionalne in situacijske nege zaradi nadmorske višine in strani neba, sta zelo izpostavljeni vetrolomom, zato bi bilo pri odkazilu smiselno slediti načelom situacijske nege ali redčenja v skupinah. Za območje naše raziskave, ki bo najverjetneje tudi v prihodnosti zelo izpostavljeno ujmam, kot so vetrolomi, je situacijska nega primernejša od tradicionalne tudi zaradi svojih tehničnoekonomskih lastnosti.

Secondary title:	Traditional and situational young forest tending following natural disturbances in the Kamnik area
Secondary abstract:	In the light of climate change, natural disturbances and difficult economic conditions, we are faced with the question of how to do tending of largest possible areas of young forest quickly and with limited resources. Our two primary goals in this Master's thesis were to evaluate the restoration of forest areas affected by natural disturbances such as windthrow and gradations of bark beetle using quantitative methods, and to perform a comparison of situational and traditional forest management on two plots with an older development phase restored after natural disturbance. Comparison of quantitative methods has shown, that the areas were mostly restored in accordance with the goals of ecological rehabilitation, which means a high proportion of pioneer and other economically less important species. The methods might need improvement, because, most likely due to overly conservative reference values in the calculations, they display an image of restoration that may not match the real restoration progress. Due to its transparency and simplicity we evaluated the analysis of older development phases using the method of structural and ecological restoration using cells as a useful tool for rapid assessment of forest development after natural disturbances. On both plots, we found higher percentage of successfully restored plots within the goals of ecological, rather than structural restoration. Since both plots where we compared traditional and situational management are highly exposed to windthrows, due to their altitude and aspect, following the principles of situational management or thinning of clusters might be better suited than traditional management. Also due to the technical and economic properties of situational tending, it is more suitable than traditional tending for the area of our research, which will most likely also be exposed to windthrows in the future.
