Baltic infralittoral bottoms dominated by Dreissena polymorpha
Description (English)
Baltic bottoms in the photic zone of which sessile/semi-sessile epibenthic bivalves cover at least 10 % of the seabed 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
Geographic range
Estonian west coast and eastern Gulf of Finland
