Baltic hydrolittoral mixed sediment characterized by Potamogeton perfoliatus and/or Stuckenia pectinata

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. Submerged rooted plants cover least 10 % of the seabed and more than other perennial attached erect groups. Out of the submerged rooted plants, pondweed constitutes at least 50 % of the biovolume.
Physical environment
Salinity range: <6 psu; Exposure range: sheltered;
Characteristic species
Potamogeton perfoliatus, Stuckenia pectinata
