| Definition | Moderately exposed lower eulittoral bedrock characterised by mosaics of the wrack Fucus serratus and turf-forming red seaweeds including Osmundea pinnatifida, Mastocarpus stellatus or Corallina officinalis. The hydroid Dynamena pumila can occur in dense populations on the F. serratus fronds whilst the sponge Halichondria panicea can cover the bedrock beneath. Underneath the canopy a number of other red seaweeds may be present including Palmaria palmata, Lomentaria articulata,Membranoptera alata and Chondrus crispus. Green seaweeds such as Cladophora rupestris, Enteromorpha intestinalis and Ulva lactuca are present though usually in small numbers. In addition, such shores provide a greater number of permanently damp refuges between the stones and underneath the seaweed canopy. Within these micro-habitats species such as the limpet Patella vulgata, the barnacle Semibalanus balanoides or the whelk Nucella lapillus can be found in lower abundance than higher up the shore. If a few boulders are present then the winkle Littorina littorea and the crab Carcinus maenas can be found on or underneath the boulders. | |
