| Preferred label | [Corallina officinalis] and [Mastocarpus stellatus] on exposed to moderately exposed lower eulittoral rock |
| 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. Situation: This community usually forms a distinct band just above the kelp zone (Ala, Ala.Ldig or Ldig). It can be found below the barnacle and [P. vulgata] dominated biotopes (Cht; Sem.Sem; Sem.FvesR). Temporal variation: If there is many of the characteristic [H. elongata] buttons present in early spring careful comparison with the Him biotope should be made (See Similar biotopes). |
