The thesis is a result of a 2-year floristic mapping (vegetation seasons 2007 and 2008) of basin of river Otava in the sector Strakonice {--} Zátavský most near Hradiště. The thesis includes characteristic of various vegetation biotopes, phytocoenosic recording, a short description and evaluation of distinctive species occurrence. A characteristic of area of interest geomorphologic, geologic, hydrologic, soil, climatic and other conditions) is provided in the form of a literary recherche.

The aim of this thesis is to evaluate the inter-annual differences in species composition of selected stands of a wet meadow ecosystem in relation to determining meteorological parameters. Changes in plant communities were studied in selected parts of the Wet meadows near Třeboň. Inter-annual differences were found only in the cover of dominant species, but not in the constancy of species.The average cover of Phalaris arundinacea was greater in 2007 than in 2006. A further increase was observed in 2007 in the cover of Calamagrostis canescens, whose presence on the wet meadows was previously limited by the floods in 2002. Calamagrostis canescens again appeared on the Wet meadows in 2006, but its growth was promoted only in the drier year 2007. The results show that the community is relatively stable in relation to short-term fluctuations of the weather.

The thesis deals with degradation of wetland vegetation in the southeastern Bohemian-Moravian Highlands. Based on detailed historical data, a comparison between the historical (20 years ago) and current state of selected wetland sites in the vicinity of Velké Meziříčí town was made. Historical development, current vegetation description and comparison with the historical situation are described for each locality. The results of the work are based on the testimony of witnesses, consultations with the author of the main historical source, maps and own floristic and phytosociological surveys that took place in 2015–2018. 23 sites were resurveyed in total, where 20 of them were found as more or less degraded. Seven of the wetland sites disappeared at all. Furthermore, local extinction is illustrated on six selected endangered wetland species. An integral part is the identification of the causes of degradation, where vegetation succession following the absence of management, drainage and nutrient input (eutrophication) are of the highest importance. Restoration options based on practical examples of good care are described to solve degradation. Phytosociological plots, photographs and lists of found species can be found in the annexes.

This thesis is focused on the evaluation of succession on spoil heap complex Petr Bezruč and spoil heap of the coking plant Svoboda since the last research carried by Koutecký (2004) and the care proposal of similar devastated sites. A total of 100 phytosociological relevés were made and 100 soil and 204 dendrochronological samples were taken on both sites. The analysis of the obtained data revealed identical changes of EIV on both sites, indicating the canopy increase of the tree species and alteration of the species composition, which was attributed to the ongoing succession. The difference among plots on spoil heaps and the difference among both spoil heaps was also evaluated. Spontaneous and directed succession was determined as the most appropriate means of restoration.

The theme of this diploma thesis was effect building a golf course on the environment - EIA Czech Krumlov. On location Kvítkův Dvůr in Czech Krumlov was suggested build an 18-hole golf course. Construction of a golf course in this area may significantly distort the historical landscape. On the given locality conducted a biological exploration. Research has proved that there are no rare or endangered plant and animal species, therefore, the realization was possible. However Kvítkův Dvůr is an important cultural monument, which falls into the protection zone urban conservation.

Vegetation sampling was carried out to determine processes of succession of aquatic and wetland plant species. Different stages of wetland and aquatic vegetation were analyzed in sand pits in the Třeboňsko Protected Landscape Area in the Czech Republic. Moreover different sizes of phytosociologial relevés of aquatic vegetation were analyzed to determine sufficient size for detection of successional changes.

The biodiversity of vascular plants and invertebrates (beetles) was studied on the strips by the railway track during two years in South Bohemia. The phytocenological mapping and pitfall trapping was used for the studying of model groups. The biodiversity of both studied groups was relatively high with different ecological characteristic of its communities. The both hygrophilous and xerophilous species occur in locality. The ubiquitous eurytopic species of beetles prevail in communities, but the rare specific species were found also. The number of specimen of both invasive and rare plant species was low. The railway track play the important role of biocentrum more for invertebrates than plants.

The point of that experiment was checking on status of selected areas with appearance of Dactylorhiza majalis and Dactylorhiza fuchsii around České Budějovice in south Bohemia. On 4 areas there were finding of biometric charakteristics always 40 selected plants and theirs mutual correlation in fact of more detailed knowing of status of individual population those kinds in particular area. There was always completed also phytocoenotic characteristics of the area. The graduation theses also includes updated information about few others tenths of areas of different kinds of orchids in České Budějovice and Český Krumlov area. Part of the experiment is map display of areas of the orchids. In map there are picture only areas with GPS not others.
