LS.LSa.MoSa.Ol Oligochaetes in littoral mobile sand
Published date 2015-03A species-poor community of oligochaetes occurring in estuarine conditions where sands and gravel are associated with the lower shore river channel in estuaries. The sediment is relatively coarse and ...
LR.HLR.MusB.Cht.Lpyg Chthamalus spp. and Lichina pygmaea on steep exposed upper eulittoral rock
Published date 2015-03Areas of steep and vertical rock in the upper eulittoral on very exposed to moderately exposed shores characterised by tufts of the dark brownish lichen Lichina pygmaea and the barnacles Chthamalus mo...
IR.HIR.KFaR.LhypPar Sparse Laminaria hyperborea and dense Paracentrotus lividus on exposed infralittoral limestone
Published date 2015-03This biotope is known from only one location, the Aran Islands, Co. Galway. Here, a limestone platform between 3 m and 6 m of depth is dominated by a dense population of the urchin Paracentrotus livid...
CR.HCR.FaT.BalTub Balanus crenatus and Tubularia indivisa on extremely tide-swept circalittoral rock
Published date 2015-03This biotope typically occurs on upward-facing, extremely tide-swept, circalittoral bedrock, boulders and cobbles found in a broad spectrum of wave-exposures. It is characterised by a few species that...
IR.LIR.K.LhypLoch Mixed Laminaria hyperborea and Laminaria ochroleuca forest on moderately exposed or sheltered infralittoral rock
Published date 2015-03Mixed Laminaria hyperborea and Laminaria ochroleuca forest on upper infralittoral moderately exposed or sheltered rock is restricted to the coast of Cornwall and the Isles of Scilly. Unlike L. hyperbo...
CR.HCR.XFa.ByErSp.Eun Eunicella verrucosa and Pentapora foliacea on wave-exposed circalittoral rock
Published date 2015-03This variant typically occurs on wave-exposed, steep, circalittoral bedrock, boulder slopes and outcrops, subject to varying tidal streams. This silty variant contains a diverse faunal community, domi...
LS.LMx.Mx.CirCer Cirratulids and Cerastoderma edule in littoral mixed sediment
Published date 2015-03Sheltered mixed sediments, usually subject to variable salinity conditions. Banks of shell may be present. The infauna is very diverse, dominated by a range of polychaetes including Exogone naidina, S...
