Site description
The valley of the Odra river between Kostrzyn town, Szczeciñski lagoon (c.150 km long) and D¹bie lake. At its widest part the Odra has two main channels˜the Eastern Odra and the Regalica. The area between the main channels is a marshy plain with oxbow lakes and many smaller channels, and is covered by fens, seasonally flooded meadows, swamps and riparian forest. D¹bie lake is a large, shallow delta-lake (5,600 ha, up to 4 m deep). Human activities include boat traffic, cattle-grazing and haymaking, angling, and hunting.

Key biodiversity
One of the most important places in Poland for roosting geese Anser and Grus grus on autumn passage, with up to 40,000-45,000 Anser fabalis and A. albifrons in the area.
