Ornithological information There are important numbers of breeding Botaurus stellaris and Alcedo atthis. Breeding species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (1-2 pairs) and Crex crex (a few calling males). Other notable breeding species include Aythya ferina (min. 20 pairs) and Dendrocopos medius (min. 6 pairs).
Site description This site covers the upper part of a reservoir used for generating hydroelectric power, and includes some islands as well as surrounding forests, swamps and meadows.

Management considerations Due to hydropower generation, the water-levels of the reservoir fluctuate between day and night by as much as 0.5 m, although by less in summer. A serious impact on birds is predicted, although this has not yet been investigated.
