Site description A stretch of the Barycz river valley between ¯migród in the west and the vicinity of Przygodzice in the east. Habitats include five large and five small complexes of fishponds, totalling 130 ponds in all, as well as surrounding meadows, arable fields, marshy areas and forests. Extensive meadows at Odolanów are mainly wet and have a dense drainage system which is cleared every few years with limited effectiveness. Mechanized hay-cutting is carried out in June and July. Some fish-eating birds are controlled (mainly Ardea cinerea and Phalacrocorax carbo).

Key Biodiversity An important area for breeding, moulting and migrating waterbirds. A total of 276 bird species have been recorded (including 126 waterbirds), of which 166 have bred (including 56 waterbirds).
