Site description This storage reservoir on the Ma³a Panew river is used for facilitating navigation on the Odra river. The eastern part of this long reservoir, between the Lubawka river mouth and Szczedrzyk village, is important for birds. The water-body is surrounded mainly by forest. The western and part of the southern shores are embanked, the northern and eastern shores are covered with water-fringe vegetation, mainly reed-grass Glyceria and willow Salix bushes. There are considerable fluctuations in water-level. At low water a large area of sandy and muddy bottom is exposed at the eastern end. The reservoir is only periodically full.
Key Biodiversity More than 20,000 ducks and waders occur here on migration or in winter, the main species being Anas platyrhynchos, A. crecca, Gallinago gallinago, Calidris alpina, C. ferruginea, C. minuta, Tringa nebularia, T. glareola, and Actitis hypoleucos. Since 1976 the abundance and species-richness of birds have grown as the vegetation has developed. Breeding species of global conservation concern that do not meet IBA criteria: Crex crex (1-2 pairs).
