Site description
The Ner valley is a marshy stretch of the Warszawa-Berlin valley between the towns of £êczyca and D¹bie, and adjoins the Bzura river valley. Wet meadows dominate the area, but on low-lying land and adjacent to water there are reedbeds Phragmites in some places, as well as riverine forest and scrub, on the more elevated, drier ground, dry broadleaved forest. The easternmost part of the valley (around £êczyca and B³onia towns) was drained in 1980, and is now less attractive to waterbirds. Other parts of the valley flood annually. The most interesting area ornithologically is around D¹bie town.
