Baltic infralittoral rock and boulders characterized by sparse epibentic bivalves

Description (English)

Baltic bottoms in the photic zone with at least 90 % coverage of rock, boulders or stones of more than 63 mm in diamete, characterized by epibentic bivalves. Sessile/semi-sessile epibenthic bivalves cover 10 % or less of the seabed and more than other perennial attached erect groups.
Physical environment
Salinity range: All; Exposure range: all, more common in exposed areas; Depth range: photic zone
Characteristic species
Mytilus spp, Dreissena polymorpha
Quality descriptors
Diversity, abundance and biomass of fauna associated with the mussel beds.
Geographic range
Whole Baltic Sea
