Baltic hydrolittoral mixed sediment habitats characterized by Zostera marina

Description (English)

Baltic hydrolittoral bottoms (with level fluctuations due to tide or weather) in the photic zone with more than 10 %, but less than 90 % coverage of both hard and soft substrata.dominated by Submerged rooted plants cover least 10 % of the seabed and more than other perennial attached erect groups. Out of the submerged rooted plants, common eelgrass constitutes at least 50 % of the biovolume.
Physical environment
Salinity range: >6 psu; Exposure range: moderate to high;
Characteristic species
Zostera marina
Geographic range
Whole Baltic Sea
