Site description A large unregulated stretch of the Wis³a (Vistula) river, from Go³¹b village to P³ock town (226 km long), with numerous sand islands. Some islands are bare, others have a herb layer, and high islands have scrub of willow Salix and poplar Populus. There are sand-dunes. The riverbanks and flood terrace are used mainly for intensive collection of willow Salix stems (for planting on riverbanks, dunes, etc., and as material for crafts), and intensive cattle-grazing on meadows and pastures. The river is used by boat traffic.

Key Biodiversity An important site for staging migrants such as waders and passerines, and for wintering waterbirds, of which more than 20,000 occur regularly, mainly ducks. Breeding species of global conservation concern that do not meet IBA criteria: Aythya nyroca (two pairs), Crex crex (five pairs).
