Baltic hydrolittoral rock and boulders dominated by perennial filamentous algae

Baltic bottoms in the hydrolittoral zone (with level fluctuations due to tide or weather) with at least 90 % coverage of rock, boulders or stones of more than 63 mm in diameter. Perennial attached algae covers at least 10 % of the seabed, and more than other perennial attached erect groups. Out of the perennial attached algae perennial filamentous species constitute at least 50 % of the biovolume.$$$Physical environment $$$Salinity range: all((( Exposure range: all((( $$$Characteristic species $$$Polysiphonia spp, Aegagrophila linnaei, Cladophora rupestris$$$Quality descriptors $$$Lower limit of vegetation, amount of epiphytic algae$$$Geographic range $$$Whole Baltic Sea
