Added to the Montreux Record, 6 June 2005. Floodplain forests, fishponds and extensive wet meadows subject to fluctuating water levels along the meandering Odra River. Vegetation includes climax, hardwood forest communities. Situated along an important bird migration route, the site supports numerous species of staging and breeding birds. Because the river remains unregulated, its natural hydrologic regime persists today. Human activities include recreation, agriculture and intensive fish production. Eutrophication due to substantial concentrations of agricultural runoff, unsuitable agricultural management and intensive fishpond management are the primary threats to the site.
