Seagrass and rhizomatous algal meadows in Black Sea freshwater influenced infralittoral muddy sands

Description (English)

Sheltered shallow (0.5-2 m) coastal waters such as embayments, inlets, bights, harbours and estuaries, more or less influenced by freshwater (salinity 0.5-10 psu), where sedimentary stability leads to muddy sands. Mixed or monospecific meadows are formed by Zostera noltei, Ruppia maritima, R. cirrhosa, Chara spp.,Stuckenia pectinata (synPotamogeton pectinatus), Najas minor and Ranunculus baudotii. Algae commonly found include species of Cladophora and Ulva which are tolerant of very low salinities.
