4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

Vast dune area with dry, shifting and humid locations with a big variety of plant species. The adjacent salt marshes are included in the Waddenzee site (NL1000001), the beaches in Noordzeekustzone (NL9802001)

4.2 Quality and importance

One of the ten most important sites for the habitat types Fixed dunes with herbaceous vegetation ("grey dunes"; 2130). One of the most valuable dune-areas of Holland. Very important site for embryonic shifting dunes, white dunes, dunes with Salix repens and humid dune slacks. Important site for decalcified fixed dunes with Empetrum nigrum. Very important for birds of dunes, reedlands and forests and as roost for many migrating birds.
