The aim of this thesis is to summarise the current knowledge of the effects of amelioration entervention especially drainage on wet meadow vegetation.

It describes how the loss of water and degradation of soil influence the plant communities of wetlands. Drainage of wetlands was very common due to the intensification of agriculture in the past. The amelioration intervension resulted in the loss of peat horizon in soil and reduction of biodiversity. This review explains the reasons to common drainage in the past. In conclusion of the review, the thesis evaluates the efficiency and possibilities of wetland biotopes restoration. The second part of the thesis describes the specific research in the village Senotín (running between 2015 and 2016) which compared the results of the studies from 1996 and 2016.
