Site location and context
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

Pressure/threats to key biodiversity
Heavy water-pollution is a threat, originating from agriculture, industry (chemical, harbour operations, ships and energy) and domestic sewage (from local and upstream sources). Disturbance of birds also occurs.
