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.
