Baltic photic mixed substrate dominated by perennial non-filamentous corticated red algae

Description (English)

Baltic bottoms in the photic zone with more than 10 %, but less than 90 % coverage of both hard and soft substrata. Perennial algae covers at least 10 % of the seabed and more than other perennial attached erect groups. Out of the perennial algae, perennial non-filamentous corticated red algae constitutes at least 50 % of the biovolume.
Physical environment
Salinity range: moderate to high; Exposure range: moderate to high; Depth range: photic zone from about 3 meters.
Characteristic species
Furcellaria lumbricalis
Geographic range
Baltic Sea up to the Archipelago Sea in the north and central Gulf of Finland in the east
