Atlantic and Baltic moist and wet dune slack

Description (English)

Dune slacks develop in Atlantic and Baltic dune systems as moist-wet depressions between dune ridges. Primary slacks originate from the development of the beach-dune-slack-system, while secondary slacks occur where blow-outs have lowered the sand level of dune systems to that of groundwater or, unusually in the Wadden Sea, where parts of barrier islands are occasionally flooded by tidal inundation (so-called

Indicator species

Diagnostic species
Constant species
Dominant species
Flowering Plants Salix repens
Flowering Plants Hydrocotyle vulgaris

Diagnostic species occur concentrated in the habitat in question, but are absent or rare in other habitats. They are good positive indicators of the habitat, but they do not need to occur in every location of the habitat.
