Mudflats and sandflats not covered by seawater at low tide
Sands and muds of the coasts of the oceans, their connected seas and associated lagoons, not covered by sea water at low tide, devoid of vascular plants, usually coated by blue algae and diatoms. They are of particular importance as feeding grounds for wildfowl and waders.
Note: Eelgrass communities (Palaearctic 11.3) are included in this habitat type.

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 2007-2012 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.
