Published date 2015-03Shingle or gravel shores, typically with sediment particle size ranging from 4 - 256 mm, sometimes with some coarse sand mixed in. This biotope is normally only found on exposed open coasts in fully m...
SS.SSa.CMuSa.AalbNuc Abra alba and Nucula nitidosa in circalittoral muddy sand or slightly mixed sediment
Published date 2015-03Non-cohesive muddy sands or slightly shelly/gravelly muddy sand characterised by the bivalves Abra alba and Nucula nitidosa. Other important taxa include Nephtys spp., Chaetozone setosa and Spiophanes...
LR.FLR.Lic.YG Yellow and grey lichens on supralittoral rock
Published date 2015-03Vertical to gently sloping bedrock and stable boulders in the supralittoral (or splash zone) of the majority of rocky shores are typically characterised by a diverse maritime community of yellow and g...
CR.MCR.EcCr.CarSp Caryophyllia smithii, sponges and crustose communities on wave-exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the upper and vertical faces of wave-exposed, moderately strong to weakly tide-swept, circalittoral bedrock or boulders, with a water depth range of 20-30m. This often...
LS.LMu.UEst.Hed.Cvol Hediste diversicolor and Corophium volutator in littoral mud
Published date 2015-03Sheltered estuarine shores of sandy mud, which may become firm and compacted if present in the upper shore where there is more time for drainage between high tides. An anoxic layer is usually present ...
LR.LLR.FVS.FserVS Fucus serratus and large Mytilus edulis on variable salinity lower eulittoral rock
Published date 2015-03Areas of very sheltered lower eulittoral rock or mixed substrata subject to variable salinity, which support an impoverished community dominated by the wrack Fucus serratus. The hydroid Dynamena pumil...
LR.HLR.FR.Pal Palmaria palmata on very exposed to moderately exposed lower eulittoral rock
Published date 2015-03Very exposed to moderately exposed lower eulittoral rock which supports a pure stand of dulse Palmaria palmata as a dense band or in large patches above the main kelp zone. P. palmata favours shaded o...

SS.SMx.CMx.FluHyd Flustra foliacea and Hydrallmania falcata on tide-swept circalittoral mixed sediment
Published date 2015-03This biotope represents part of a transition between sand-scoured circalittoral rock where the epifauna is conspicuous enough to be considered as a biotope and a sediment biotope where an infaunal sam...
