Identification of marine natural habitat types in the Wadden Sea of Schleswig-Holstein according to FFH

The Habitats Directive (FFH) of the European Union (EU) describes for coastal seafloors that are permanently covered by water (subtidal) three so called marine natural habitat types. These compartments have to be monitored and evaluated, and their status has to be reported every six years to the EU by the responsible authority.  The relevant habitat types are "subtidal sandbanks", "large shallow inlets and bays", and "reefs". In the scope of the implementation of the Habitats Directive mandatory definitions and mapping instructions have been recommended that mainly base on the geological setting of the site.
