In Western Europe, this habitat type includes a wide variety of dune habitats: stagnant water bodies, pre-vegetated areas, patches of minerotrophic fens, wet meadows (often with short willows, see habitat type 2170), sedge shrubs, and club-rush beds. This diversity of habitats also results in extremely diverse vegetation.
In Estonia, this habitat type should also include the black alder marshes behind or between old coastal dunes, which are flooded by seawater during storms.
Humid dune slacks can be found here and there on the entire continental coast and islands; the coastal marsh forests are more common in Pärnu County, in some places also on the coasts of the Lääne County and Lääne-Virumaa County (in Lahemaa).
