Moderately exposed to sheltered full salinity upper eulittoral mixed substrata characterised by a band of the wrack Fucus spiralis. Occasional clumps of the wrack Pelvetia canaliculata can be overgrowing the black lichen Verrucaria maura and the olive green lichen Verrucaria mucosa. On the more stable boulders underneath the fronds the red crust Hildenbrandia rubra can be found along with the barnacle Semibalanus balanoides and the limpet Patella vulgata. The winkles Littorina littorea and Littorina saxatilis can be found on and among the boulders and cobbles, while amphipods and the crab Carcinus maenas can be present either underneath the boulders or among the brown seaweeds. The green seaweed Ulva intestinalis can occur in some abundance especially during the summer.
