Preferred label [Osmundea pinnatifida] on moderately exposed mid eulittoral rock
Definition Exposed to moderately exposed lower eulittoral rock characterised by extensive areas or a distinct band of [Osmundea pinnatifida] and [Gelidium pusillum] (either together or separately). This community usually occurs on shores on which a fucoid canopy is reduced in extent, or even absent. Other turf-forming red seaweeds, such as [Corallina officinalis, Mastocarpus stellatus], [Ceramium] spp. and [Callithamnion hookeri] may be present, although [O. pinnatifida] always dominate. On flatter, more sheltered shores, [Osmundea hybrida] may also occur. Small patches of bare rock amongst the algal turf are occupied by barnacles [Semibalanus balanoides], the limpet [Patella vulgata], the whelk [Nucella lapillus] and small individuals of the mussel [Mytilus edulis]. The winkles [Littorina littorea] and [Littorina saxatilis] can be present on the rock or among the seaweeds. A variation of this biotope has been described for the chalk platforms in Kent where extensive turfs of [G. pusillum] occur in the mid eulittoral above the main [O. pinnatifida] zone. Situation: This biotope can be found below barnacles [S. balanoides] or red seaweed dominated community, which includes the species [Palmaria palmata], [C. officinalis] or [M. stellatus] (Sem; Coff; Cor). It is found above biotopes dominated by the wrack [Fucus serratus] and red seaweeds (FcdR; MytFR; Fser.R) or above biotopes dominated by the kelp [Laminaria digitata] (Ldig.Ldig).
