Unvegetated Atlantic littoral mixed sediment

Description (English)

Eulittoral mixed substrata where the substratum is too mobile or disturbed to support a seaweed community (MA4-231). 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.
