Structure and development of natural and combined regeneration in spruce stands affected by bark beetle disturbances in the Šumava Mts.
 Dorko, Jakub ; Vacek, Stanislav (advisor) ; Karel, Karel (referee)
This bachelor thesis is dealing with structure, progress and dynamics of mountain spruce forests in areas afflicted by large bark beetle gradation in area of National Park Bohemian Forest, specifically in the municipality of Modrava. The research was carried out on 9 permanent research plots and it was based on evaluation of structure of the forest reconstruction, height measurement and increments of each individuial tree of natural reconstruction. The measurement was made in autumn 2015. 3 plots of those 9 permanent research plots were situated in forest clearing and the rest in dead forest. Combination of natural and artifical restoration of forest was applied in these plots. Differences were found out in quantity and structre of reconstruction in connection with various stand types. It was discovered that in west oriented locations (PRP 1 to 6), the reconstruction prospers and grows quicker, compared with north orientation (PRP 7 to 9). The highest dimensions were reached by the reconstruction in the plots founded in the forest clearing, on the contrary the highest density of the reconstructon was discovered in the plots with dead forest. The highest value of average increment was discovered in PRP 4, which means in forest clearing where logging had been done.
