Mediterranean and Black Sea moist and wet dune slack

Description (English)

Small permanent or temporary freshwater bodies that develop in the depressions between sand ridges in the dune systems along the Mediterranean and Black Sea coasts. The constituent vegetation depends on the depth and persistence of the water which is very variable, and also on the level of enrichment, which is usually eutrophic to mesotrophic, though locally dystrophic. There can be aquatic communities in the open waters and swamps around the margins and, where the slacks dry out in summer, conditions can become saline with ephemerals colonising.

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.
