Abstract

Naravne ujme v kombinaciji s podnebnimi spremembami postajajo pomemben vplivni dejavnik na gospodarjenje z gozdovi. V okviru magistrskega dela so bili na podlagi prejšnjih raziskav v prvem delu analizirani različni kvantitativni načini preverjanja uspešnosti obnove gozdov po naravnih ujmah. V drugem delu magistrskega dela so bili izbrani trije primeri sestojev, na katerih je bila primerjana tradicionalna in situacijska nega. Ugotovljeno je bilo, da je kvantitativne analize mladja možno izpeljati sorazmerno hitro, njihova izvedba pa je smiselna tudi v sestojih, poškodovanih po naravnih ujmah. V raziskavi je bilo ugotovljeno, da je kvantitativna analiza pomlajevanja poleg kvalitativnih analiz pomemben del načrtovanja obnove poškodovanega gozda. Ugotovljeno je bilo, da so bili objekti raziskave dobro obnovljeni, pri čemer je nujno ustrezno upoštevati pionirske vrste. Za ustrezno obnovo gozdov je ključnega pomena ustrezna nega mlajših razvojnih faz. Na treh izbranih primerih strukture sestojev je bilo ugotovljeno, da je za dobro pomlajene površine smiselno uporabiti situacijsko in prilagojeno tradicionalno nego z manj izbranci. Na slabše pomlajenih površinah je smiselna uporaba situacijske in skupinske nege. Rezultati nakazujejo tudi na možnost racionalizacije nege preko zmanjševanja števila izbrancev, usmerjene odsotnosti izvedbe redčenja pionirskih drevesnih vrst ter prilagoditve ukrepov pri leskovih šopih.

Secondary title:	Regeneration success and young forest tending following natural disturbances in the Kočevje region
Secondary abstract:	Natural disturbances combined with climate changes are becoming important part of forest management. In this master's thesis, based on previous research, various quantitative methods of verifying success of forest restoration after natural disturbances were analyzed. In the second part of research, three examples of forest stands were analyzed, in which situational thinning and classical thinning were compared. It was established that quantitative analyses of seedlings could be performed relatively quickly. Implementation of these methods is reasonable especially in stands, damaged by natural disturbances. It was also concluded that, beside qualitative analyses, a quantitative analysis of forest regeneration represents an important part of damaged forest restoration. Research objects were proved to be well regenerated, with due regard to pioneer species. Adequate tending of younger forest stages is crucial for proper forest restoration. On three selected examples of forest structure analyses it was found that on well-rejuvenated stands it makes sense to use situational or adapted classical thinning. On poorly rejuvenated stands it makes sense to use situational and group thinning. Results indicate possibility of rationalizing tending by reducing number of selected trees, not reducing pioneer species and adjustment of reduction of hazel bushes.
