Concept: Maerl beds in the eunishabitats vocabulary

Concept URI	http://eunis.eea.europa.eu/eunishabitats/A5.51
Preferred label	Maerl beds
Definition	Beds of maerl in coarse clean sediments of gravels and clean sands, which occur either on the open coast or in tide-swept channels of marine inlets (the latter often stony). In fully marine conditions the dominant maerl is typically [Phymatolithon calcareum] (A5.511), whilst under variable salinity conditions in some sealochs beds of [Lithothamnion glaciale] (A5.512) may develop.
