Baltic hydrolittoral mixed sediment characterized by sparse or no macrocommunity

Description (English)

Baltic hydrolittoral bottoms (with level fluctuations due to tide or weather) in the photic zonewith less than 90 % coverage of mixed soft and hard substrata. Sparse (less then 10% cover) or no macrovegetation, no macro- epi- or infauna
Physical environment
Substrate is soft or crystalline rock, boulders or stones mixed with mobile substrates such as sand or coarse substrate. Depth range: photic zone
Characteristic species
meiofauna, bacteria
Geographic range
Whole Baltic Sea
