Humid dune slacks
Description (English)
Humid depressions of the dunal systems. Humid dune-slacks are extremely rich and specialised habitats very threatened by the lowering of water tables.
Subtypes:
Pal. 16.31: Dune-slack pools (Charetum tomentosae, Elodeetum canadense, Hippuridetum vulgaris, Hottonietum palustris, Potametum pectinati): freshwater aquatic communities (cf. Pal. 22.4) of permanent dune-slack water bodies.
Pal. 16.32: Dune-slack pioneer swards (Juncenion bufonii p.: Gentiano-Erythraeetum littoralis, Hydrocotylo-Baldellion): pioneer formations of humid sands and dune pool fringes, on soils with low salinity.
Pal. 16.33: Dune-slack fens: calcareous and, occasionally, acidic fen formations (cf. Pal. 54.2, 54.4, in particular 54.21, 54.2H, 54.49), often invaded by creeping willow, occupying the wettest parts of dune-slacks.
Pal. 16.34: Dune-slack grasslands: humid grasslands and rushbeds (see Pal. 37.31, 37.4) of dune-slacks, also often with creeping willows (Salix rosmarinifolia, Salix arenaria).

Conservation status
EU conservation status
Conservation status assesses every six years and for each biogeographical region the condition of habitats and species compared to the favourable status as described in the Habitats Directive. The map shows the 2013-2018 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.
