Baltic infralittoral rock and boulders characterized by sparse Dreissena polymorpha

Description (English)

Baltic bottoms in the photic zone with at least 90 % coverage of rock, boulders or stones of more than 63 mm in diameter. Epibenthic bivalves cover at least 10%of the seabed and more than other perennial attached erect groups. Out of the epibenthic bivalves Dreissena polymorpha constitutes at least 50 % of the biomass.
Physical environment
Substrate is rock and/or boulders. Depth is typically from 2 to 10 meters. Appears in sheltered to moderately exposed areas. Salinity must be less than 5 psu.
Characteristic species
Dreissena polymorpha
Quality descriptors
Amount of sediment and epiphytic annual algae. Diversity, abundance and biomass of fauna.
Geographic range
Estonian west coast and eastern Gulf of Finland
