Nowadays, more information is available about the activities of the Eurasian beaver (Castor fiber) as an ecosystem engineer species and the resulting ecosystem services. The environment-shaping activity of beavers not only affects the bed conditions of a given body of water but also affects the degree of diversity of the vegetation and fauna surrounding it. The research published in connection with this topic has only in recent years begun to deal more intensively with the condition characterisation and function analysis of the flooded areas under constant beaver influence, called beaver meadows. The focus of this paper is the investigation of beaver meadows directly connected to the dam system consisting of 19 beaver dams located along the Ablánc stream. The research examines the effect of the activity of the beaver colony, which has been continuously monitored for almost two years, on the soil moisture conditions of the beaver meadows in the Natura 2000 nature conservation area and to what extent this is reflected in the characteristics of the plant community. The focus of the analysis is the vertical distribution of soil moisture in the upper soil layer. During the vegetation mapping, 10 squares were designated to determine plant community parameters. High soil moisture values were detected in the examined quadrates, which varied between 39.0 f% and a maximum of 50.0 f%. A significant number of taxa could be identified - such as Myosoton aquaticum and Petasites hybridus - whose primary ecological requirements are a permanent wet environment and continuous water impact. |
