Abstract

Analizirano območje v GGE Blagovica je leta 2008 prizadel vetrolom, leta 2014 pa žledolom. Analizirali smo razvoj mladja, drevesno sestavo in višinsko strukturo mladja na prizadetih površinah, ki so sedaj prepuščene naravnemu procesu obnove. V oddelkih na objektih Golčaj (pred ujmo normalen sestojni sklep), Golkar (pred ujmo vrzelast sestojni sklep) in Vetrolom (poškodovan zaradi vetra) smo postavili 12 ploskev, na vsaki poškodovani površini po štiri in dve z namenom kontrole v sestojih, ki v ujmah niso bili poškodovani. Ploskve so bile v velikosti 5 x 5 m. Na ploskvah se je najpogosteje pojavljalo mladje bukve, črnega gabra, velikega jesena, gorskega javorja, malega jesena, gorskega bresta, smreke. Gostota mladja na objektu Golkar je večja kot na objektu Golčaj zaradi večjega dotoka svetlobe v sestoj pred ujmo, zeliščnega sloja pa je več na objektu Golčaj. V obeh objektih je največ mladja do višine 20 cm, nasemenitev je potekala ob istem času. Mladje, ki je višje od 50 cm, se je nasemenilo že pred ujmo. Na objektih Golkar je največ mladja bukve in velikega jesena, na objektih Golčaj pa je največ velikega jesena. V prihodnosti bi bila potrebna izvedba ustrezne nege, predvsem obžetev grmovnega sloja leske in zeliščnega sloja malin, robid in trav, da bi tako zagotovili dobro kakovost osebkov v naslednjih razvojnih fazah.

Secondary title: Forest development in areas damaged by ice and wind
Secondary abstract: The forest analysed in this diploma thesis was damaged by a windstorm in 2008, and in 2014 it was affected by sleet. We have analysed the regeneration in the affected area in terms of its tree structure and height. We have set up 12 plots in total in the following damaged areas: Golčaj (dense canopy before the ice storm), Golkar (scattered canopy before the ice storm), and Vetrolom (stands damaged by wind). The size of plots was 5 x 5 metres. The regeneration that was most commonly found in these plots was of the following tree species: European beech, European hop-hornbeam, European ash, sycamore maple, South European flowering ash, wych elm, and Norway spruce. Due to the fact that before the disturbance there was more light in Golkar area, the regeneration density there was higher compared to Golčaj area. The density of herb layer, however, was higher in Golčaj area. In both areas most regeneration was up to 20 cm high. Natural seeding that took place before the disturbance was the source for the regeneration that was higher than 50 cm. To achieve good quality of future stands the appropriate silvicultural measures should be carried out, primarily removal of common hazel and herb layers of raspberry, blackberry, and grass.
