Site description The widest part of the valley of the middle Obra river is characterized by forests and meadows, without larger settlements or a developed road system. The valley is divided up by channels and ditches which drain to the west (two main channels) or to the east to the Warta river via the Mosiñski channel. The principal valley habitats are wet fields, marshes, and swamp forests of Alnus. Fields are intensively cultivated; wet grassland and scrub are not common. Forest of pine Pinus and oak Quercus covers the higher elevations.
