A very large and outstanding habitat complex of archipelago, sea bays, river mouths, lagoons and eutrophic lakes at the delta of the Kokemäki river. Large areas of meadow, marsh and deciduous forest on shores considerably increase the diversity of the avifauna. Fishing, boating and hunting are common in some parts of the site.
