Site description
A marshy stretch of the Narew valley, spanning 58 km between Sura¿ town and ¯ó³tki village, and from 300 m to 4 km wide. The valley has a natural character between Sura¿ and Rzêdziny towns and is periodically flooded. The Narew is a braided, meandering river, and creates a system which occupies the whole width of the valley floor in some places. There is a very rich mosaic of plant communities˜mainly beds of reed Phragmites and sedge Carex, alder Alnus forest and riverside scrub of willow Salix.
