Vosátková, Veronika ; Lipský, Zdeněk (advisor) ; Matějček, Tomáš (referee)
The aim of this study is to bring a light into the situation of wind calamity which happened 19.11.2004. After the physicographical analysis of this locality, I will try to bring the whole picture of this catastrophe, its causes and mostly consequences left on the tatra nature. I will pay special attention to regeneration of the country and following steps in dealing with this calamity because of two different opinions on the picture of Tatras. Finally, I will discuss future progress in Tatra mountains and i will try to answer the question, whether was a worse catastrophe a wind calamity or human intervention in this locality afterwards.

Stav obnovy lesa po vichřici Emma na lesní správě Lanškroun - revír Letohrad
Černohousová, Jana
The main objective of submitted thesis was the assessment of the state and a development of forest regeneration of selected areas devastated by the wind caused by the wind disturbance Emma in 2008 in the hunting ground of Letohrad (Forest management Lanškroun). The state of recovery has been analyzed based on registration documents and a field survey. Furthermore, the analysis in the area of interest has been performed focusing on the growth of Norway spruce and a common fir in different microclimate conditions. Next it was monitored which species grows out the most in extreme conditions of clearing area. Another part of the piece dealt with the costs of sites regeneration. Based on the results, the aim of the thesis was to optimize the process of regeneration of disturbed sites in the area of interest. At selected sites of Letohrad area were identified the biggest issues connected to Norway spruce and a common fir planting. Among the main limiting factors were recognized unsuitable choice of site, extreme climatic conditions, weed infestation and a high amount of game. Spruce and fir had the most significant increment in the sites of small area element character. Planting of spruce in the third altitudinal forest zone did not increment well and was visibly lagging. On the contrary, an oak followed by a beech thrived under the same conditions. The highest costs were identified at problematic, still not established disturbed area of 309G11.

Průběh sukcese lesa na kalamitní holině Soběšice
Žouželková, Lenka
This bachelor thesis has been processed on the territory of SLP ML Křtiny - Soběšice. The aim of the study was to evaluate the development of the succession focusing especialy on woody component (years 2012-2014) on salvage glade after the disintegration of young pine small pole stage by wet snow. Data collection and analysis was conducted on the network of 87 inventory plots in 3 variants of soil preparation: without intervention (41), chemical (23) and mechanical (23). On the plots were registered seven kinds of trees, the numbers per hectare decreased gradually from 7500 to 5000 units / ha. On the whole area was dominated by hornbeam and oak. The largest occurrence and density of trees was registered in mechanical preparation. In the first two years was dominated second high-rise category. (20-50 cm) and in 2014 it was the third category from 50 to 130 cm. Altogether were found 34 kinds of herbs and shrubs. The average coverage increased from 43% in 2012 to 81% in 2014. The greatest coverage was in 2014 detected in mechanical preparation and chemical variant was the lowest. Dominating substrate of soil all the time was the mineral soil. Under current legislation the state determined of ascertained state regeneration after 5 years since the establishment of clearing does not meet the time nor the space beyond regeneration, or minimum numbers per hectare. The results showed the best use of self-development with assuming completion artificial regeneration, and interventions against weeds. It must be long-term monitoring.
