| Definition | Exposed to moderately exposed steep, lower littoral fringe rock and mixed substrata characterised by the wrack Pelvetia canaliculata and sparse barnacles Chthamalus montagui and Semibalanus balanoides. On sheltered shores the biotope is restricted to vertical faces. The limpet Patella vulgata and the wrack Fucus spiralis are usually present as well. P. canaliculata typically overgrows a crust of the black lichen Verrucaria maura or on occasion Verrucaria mucosa, in contrast to the red crust Hildenbrandia rubra on very sheltered shores. The winkle Littorina saxatilis is frequently present underneath the fronds of P. canaliculata. Some geographical variation are present and southern and western shores are typically characterised by the barnacle C. montagui or Chthamalus stellatus while S. balanoides dominates on northern and eastern shores. On mixed substrata the barnacle Elminius modestus may be present. | |
