MA4-21 - Communautés d'algues sur sédiment hétérogène du médiolittoral en Atlantique

Seaweed communities on Atlantic littoral mixed sediment

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Eulittoral mixed substrata subject to variations in salinity and/or siltation characterised by dense blankets of ephemeral green and red seaweeds (MA4-211). This is a biotope with a low species diversity and the relatively high number of species in the characterising species list are due to a variation in the species composition from site to site, not to high species richness on individual sites.
