MB4-21 - Bancs de maërl sur sédiment hétérogène de l'infralittoral en Atlantique

Maerl beds on Atlantic infralittoral mixed sediment

Classification des habitats EUNIS 2022

Descriptif de l'habitat

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 (MB3-221), whilst under variable salinity conditions in some sealochs beds of Lithothamnion glaciale (MB3-222) may develop.
