Hodnocení stavu lesních geobiocenóz přírodní rezervace Palkovické hůrky (okres Frýdek-Místek)
Žáček, Pavel
The aim of this thesis was to determine the current state of forest stands in the territory of the PR of Palkovické hůrky. On established areas, perform control measurements of dendrometric characteristics and perform phytocenological imaging on the most widespread forest types. As part of the field investigation, assess the occurrence of forestry-significant pests and pathogens on individual tree species. The results of individual phytocenological images show that herb species diversity has decreased in 75 % of forest types. However, the total cover of these species was reduced to only 58 % of forest types. From individual measurements on dendrometric plots, it was found that the vegetation stock increased in 66 % of cases. If there was a decrease in the vegetation stock, it was solely due to the death of a large number of individuals of Norway spruce, mountain elm or Norway ash. The highest increase in stock occurred in forest type 4S1, where the stock doubled. The significant die-off of spruce contributes to the improvement of the evaluation of the naturalness of forests. In the future, in the nature reserve Palkovické Hůrky, there is an assumption that within the framework of this assessment, a forest close to nature will become a natural forest. Finally, according to the facts and findings, forestry management was proposed in the given natural conditions.

Vegetation changes in transition bogs at fishpond epilitorals
Spilka, Josef ; Karlík, Petr (advisor) ; Kindlmann, Pavel (referee)
This study concerns in a three peatland sites: the epilitorals of Pilská reservoir and Hořejší Padrťský fishpond in Příbram region and Kamenný fishpond in Pilsen. These peat-bobg were affected by negative conseqences of human activities. The aim of this study is to find out what kind these changes was and what extent they were. The changes in vegetation were observed from two points of view. The GIS analyses of aerial photographs represent the macroscale view. Repeating of old phytosociological relevées was the microscale view. To understand the cause of vegetation changes, the species-environment analyses were used. Four transects were made for this purpose and a water table level, pH and conductivity were mesured monthly along these transects. One-shot measurements of N and P water concentration and a peat depth were also carried out. Measured data from transects were uses in multivariate vegetation analyses and also in one- way analysis, aimed to an expansion plant species. All three sites of concern came through strong changes in past. In all of them the area of biotops of great conservation importance decreased and some endangered plant species have been lost there. The changes in Pilská reservoir epilitoral were mostly anthropogenic, whereas the mires of Hořejší Padrťský fishpond and Kamenný...
