Vegetation of the supralittoral and upper sublittoral zones of the Western German Baltic Sea coast: a phytosociological study : Vegetation of the Western German Baltic Sea coast

• Supralittoral and shallow water seaweed communities are particularly exposed to impacts such as climate change and disturbance by humans. Therefore, their classification, the study of composition, and the monitoring of their structural changes are particularly important. A phytosociological survey of the supralittoral and upper sublittoral vegetation of the South West Baltic Sea revealed eight phytobenthos communities with two variants comprising 35 taxa of macrophytes (18 taxa of Chlorophyta, 13 taxa of Rhodophyta and four taxa of Phaeophyceae, Ochrophyta). Five of the eight communities were dominated by Ulvales (Ulva intestinalis, Kornmannia leptoderma, and three Blidingia species), the other three by Fucus vesiculosus. Most Fucus vesiculosus-dominated communities contained U. intestinalis and U. linza as subdominants. Only one of the communities had until now been described as an association (Ulvetum intestinalis Feldmann, J. (1937). Les algues marines de la Cote des Alberes. Rev. Algol. 9: 141–335). The syntaxonomic composition of the investigated vegetation includes both phytocenoses with the domination of green algae (Ulvetum intestinalis Feldmann, J. (1937). Les algues marines de la Cote des Alberes. Rev. Algol. 9: 141– 335 and communities of Blidingia marginata, unidentified Blidingia spp. and Kornmannia leptoderma), as well as a number of communities dominated by Fucus vesiculosus. Mainly boreal Atlantic species and cosmopolitans make up the bulk of the species in these associations.
