Preferred label [Bifurcaria bifurcata] in shallow eulittoral rockpools
Definition Eulittoral rockpools in south-west Britain on very exposed to moderately exposed shores dominated by the brown seaweed [Bifurcaria bifurcata] and encrusting coralline algae and [Corallina officinalis]. Kelps are present and include the species [Laminaria digitata], [Laminaria saccharina] and the wrack [Himanthalia elongata]. Underneath the canopy formed by these species is a high diversity of red seaweeds including the foliose species [Chondrus crispus], [Palmaria palmata], [Osmundea pinnatifida] and [Mastocarpus stellatus]. Other red seaweeds include [Gastroclonium ovatum], [Ceramium nodulosum], [Calliblepharis jubata] and [Mesophyllum lichenoides]. The green seaweeds [Ulva lactuca] and [Enteromorpha intestinalis] occur where space allows. Often found in small cracks and crevices are the anemones [Actinia equina] and [Anemonia viridis], while the limpet [Patella vulgata] can be found on the rock surface. Coarse gravel, cobbles and mobile boulders often cover the bottom of these rockpools, where [Gibbula umbilicalis] can be found. Situation: Rockpools throughout the eulittoral to the upper littoral fringe in bedrock on very exposed to moderately exposed shores. [B. bifurcata] is at the edge of its range in Britain; in France it occurs in deeper lower shore pools where the alga forms a noticeable band in the mid pool level, below a band of [C. officinalis] and coralline crusts. Temporal variation: The ephemeral green seaweeds [Enteromorpha intestinalis] and [Ulva lactuca] can occur during the summer.
