| Definition | Exposed lower eulittoral rock or moderately exposed lower eulittoral vertical rock that supports a dense turf of the red seaweed Corallina officinalis, often on wave surged rocky slopes. There is usually a low abundance of other turf-forming red seaweeds such as Lomentaria articulata, Mastocarpus stellatus, Palmaria palmata and Osmundea pinnatifida. Other seaweeds that occur in low abundance includes the wrack Himanthalia elongata and the kelp Laminaria digitata, while the brown seaweed Leathesia difformis can be found growing on and around the other seaweeds. Green seaweeds such as Enteromorpha intestinalis, Ulva lactuca and Cladophora rupestris are also present. The coralline turf creates a micro-habitat for small animals such as the colonial tube building polychaete Pomatoceros sp. and the barnacle Semibalanus balanoides. The mussel Mytilus edulis is often found in small cracks and crevices while the sponges Halichondria panicea and Hymeniacidon perleve can be found in shaded areas or on overhangs. The limpets Patella ulyssiponensis and Patella vulgata can be found on the bedrock underneath the turf. The brown seaweed Bifurcaria bifurcata and the barnacle Balanus perforatus may occur in the extreme south-west. | |
