Baltic hydrolittoral rock and boulders dominated by Fucus spp.

Description (English)

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 Fucus spp. constitute at least 50 % of the biovolume.
Physical environment

Fucus radicans, F. serratus, F. vesiculosus
Quality descriptors
Lower limit of vegetation, amount of epiphytic algae
Geographic range
