PHYSICOCHEMICAL PROPERTIESOF BEAVER WETLANDS WATER
IN THE KŁUDA VALLEY
Grażyna Szpikowska, Józef Szpikowski
Summary
Beavers settle entails various changes in the functioning of geoecosystems: hydrological (associated with the conditions of flow and drainage of water from the catchment and the conditions of retention), geomorphological, affecting the level of biodiversity and affecting the water quality. Research undertaken in the Kłuda catchment, a tributary of the upper Parsęta (Drawskie Lake), focused on knowledge of water chemistry within the beaver wetlands. The quality of these of waters compared with the chemistry of groundwater in the adjacent slope system and river water. It was changes in the oxygenation of groundwater and waters stagnant on the surface of beaver wetlands. Reducing conditions in the waters of beaver wetlands reduce the concentration of nitrate ions. The groundwater in the zones of beaver wetlands reduction of the concentration of sulphate ions and increase the concentration of ammonium ions and phosphate are observed. Beaver wetlands in the Kłuda catchment partially limit loads eutrophying components
