Baltic infralittoral rock and boulders characterized by annual algae

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. Annual algae cover at least 10 % of the seabed, while all other epibenthic biotic structures cover less than 10 %. Annual algae can live as epiphytes (e.g. Pilayella/Ectocarpus on Fucus spp.) Thus this biotope only occurs when annual algae dominate the substrate and not when they grow on perennial biotic structures.
