LR.HLR.FR Robust fucoid and/or red seaweed communities
Published date 2015-03This biotope complex encompasses those seaweeds that are able to tolerate the extreme conditions of very exposed to moderately exposed rocky shores. The physical stresses caused by wave action often r...
SS.SMx.IMx.VcorAsquAps Venerupis corrugata, Amphipholis squamata and Apseudes latreilli in infralittoral mixed sediment
Published date 2015-03Sheltered muddy sandy gravel and pebbles in marine inlets, estuaries or embayments with variable salinity or fully marine conditions, support large populations of the pullet carpet shell Venerupis cor...
SS.SSa.IMuSa.AreISa Arenicola marina in infralittoral fine sand or muddy sand
Published date 2015-03In shallow fine sand or non-cohesive muddy sand in fully marine conditions (or occasionally in variable salinity) a community characterised by the polychaete Arenicola marina may occur. This biotope a...
LR.MLR.BF Barnacles and fucoids on moderately exposed shores
Published date 2015-03Moderately exposed rocky shores characterised by a mosaic of fucoids and barnacles on bedrock and boulders, where the extent of the fucoid cover is typically less than the blanket cover associated wit...
IR.LIR.K Silted kelp communities (sheltered infralittoral rock)
Published date 2015-03Infralittoral rock in wave and tide-sheltered conditions, supporting silty communities with Laminaria hyperborea and/or Saccharina latissima. Associated seaweeds are typically silt-tolerant and includ...
CR.MCR.CMus Circalittoral mussel beds on rock
Published date 2015-03This biotope complex occurs on moderately wave-exposed upper circalittoral bedrock subject to strong or moderately strong tidal streams. This complex is characterised by dense aggregations of the muss...
CR.HCR.XFa.FluCoAs Flustra foliacea and colonial ascidians on tide-swept moderately wave-exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the upper faces of moderately tide-swept, moderately wave-exposed circalittoral bedrock or boulders (although a variant is found on mixed substrata). It most frequentl...
SS.SMp.Mrl.Pcal.Nmix Phymatolithon calcareum maerl beds with Neopentadactyla mixta and other echinoderms in deeper infralittoral clean gravel or coarse sand
Published date 2015-03Lower infralittoral maerl beds characterised by Phymatolithon calcareum in gravels and sand with a variety of associated echinoderms. The echinoderm Neopentadactyla mixta is frequently observed in thi...
CR.MCR Moderate energy circalittoral rock
Published date 2015-03This habitat complex mainly occurs on exposed to moderately wave-exposed circalittoral bedrock and boulders, subject to moderately strong and weal tidal streams. A few biotopes (FluCoAs.X, FluHocu) al...
CR.FCR Features of circalittoral rock
Published date 2015-03Circalittoral rock features include circalittoral fouling communities (CR.FCR.FouFa) and circalittoral caves and overhangs (CR.FCR.Cv). These features are present throughout the circalittoral zone in ...
