Marshes and reed-beds
  Reed-beds steadily took over in the well-watered valleys as they were abandoned by farmers. They also colonised the lakes as they are rich in organic matter.


They all have much the same flora, ideal nesting ground for the Common Reed Bunting (Emberiza schoeniculus),

the Reed Warbler, the Grasshopper Warbler and the Water Rail (Rallus aquaticus).

On chalky soil, the sedge marshes are covered in such typical plants as the Black Bog-rush, Grass of Parnassus (Parnassia palustris)

and Marsh Helleborine (Epipactis palustris). The Meadow Pipit nests here and the Common Snipe stays over on occasion.
