The Site includes two fish pond complexes with a total of 35 ponds, together with adjacent wet meadows, reedbeds and riparian forests. It boasts an abundant birdlife: out of 216 species observed, 48 are waterbirds. The Site is one of the most important areas in this part of Europe for resting and feeding migratory birds, and especially for bean goose Anser fabalis, with 19% of its non-breeding population supported by the Site. It is also of great importance for breeding birds, with as many as 147 species recorded, including waterbirds of European importance such as the common kingfisher Alcedo atthis, the corn crake Crex crex and the red-backed shrike Lanius collurio. Various threatened amphibians, reptiles and mammals are also present. The Site plays a valuable role in flood control and soil formation, and provides recreational, educational and scientific opportunities. It is a model for local cooperation, with the Lower Silesia Landscape Park Complex, the Polish Angling Association, the Roma People Association and other organisations working together to support traditional fisheries, promote their products and raise the awareness of fishermen of the importance of birds to the health of the ecosystem.
