Sediment-affected or disturbed kelp and seaweed communities

English name: Sediment-affected or disturbed kelp and seaweed communities

Description (English)

Infralittoral rock habitats, subject to disturbance through mobility of the substratum (boulders or cobbles) or abrasion/covering by nearby coarse sediments or suspended particulate matter (sand). The associated communities can be quite variable in character, depending on the particular conditions, which prevail. The typical Laminaria hyperborea and red seaweed communities of stable open coast rocky habitats (A3.21) are replaced by those, which include more ephemeral species or those tolerant of sand and gravel abrasion. As such Laminaria saccharina, Saccorhiza polyschides or Halidrys siliquosa may be prominant components of the community.
