SS.SBR.PoR.Ser Serpula vermicularis reefs on very sheltered circalittoral muddy sand
Published date 2015-03Large clumps (mini 'reefs') of the calcareous tubes of Serpula vermicularis, typically attached to stones on muddy sediment in very sheltered conditions in sea lochs and other marine inlets. A rich as...
IR.HIR High energy infralittoral rock
Published date 2015-03Rocky habitats in the infralittoral zone subject to exposed to extremely exposed wave action or strong tidal streams. Typically the rock supports a community of kelp Laminaria hyperborea with foliose ...
SS.SMx.CMx.ClloMx.Nem Cerianthus lloydii with Nemertesia spp. and other hydroids in circalittoral muddy mixed sediment
Published date 2015-03In sheltered muddy sandy gravel with appreciable quantities of surficial cobbles, pebbles and shells a community similar to SS.SMx.CMx.ClloMx may develop with frequent Cerianthus lloydii and other bur...
LR.LLR.F.Fves.FS Fucus vesiculosus on full salinity moderately exposed to sheltered mid eulittoral rock
Published date 2015-03Moderately exposed to sheltered mid eulittoral bedrock and large boulders characterised by a dense canopy of the wrack Fucus vesiculosus (Abundant to Superabundant). Beneath the seaweed canopy the roc...
LR.FLR.CvOv.RpurCla Rhodochorton purpureum and Cladophora rupestris on upper to mid-shore cave walls
Published date 2015-03Vertical and steeply-sloping upper walls at the entrances and inner reaches of upper to mid-shore caves that are partially sheltered from direct wave action characterised by a turf of the 'velvety' re...
LS.LBR.LMus.Myt.Mu Mytilus edulis beds on littoral mud
Published date 2015-03Dense mussel beds found in sheltered conditions on mud. There is a build up of pseudofaeces that results in a bed that is very soft to walk on, and sediment which is anoxic to the surface. Pools are o...
LR.LLR.FVS.PelVS Pelvetia canaliculata on sheltered variable salinity littoral fringe rock
Published date 2015-03Lower littoral fringe bedrock or stable boulders and mixed substrata on very sheltered to extremely sheltered variable salinity shores characterised by a dense cover of the wrack Pelvetia canaliculata...
CR.LCR Low energy circalittoral rock
Published date 2015-03This habitat complex occurs on wave-sheltered circalittoral bedrock and boulders subject to mainly weak/very weak tidal streams. The biotopes identified within this habitat complex are often dominated...
SS.SCS Sublittoral coarse sediment (unstable cobbles and pebbles, gravels and coarse sands)
Published date 2015-03Coarse sediments including coarse sand, gravel, pebbles, shingle and cobbles which are often unstable due to tidal currents and/or wave action. These habitats are generally found on the open coast or ...
CR.HCR.XFa.ByErSp.Cyl Mixed turf of bryozoans and erect sponges with Cylista elegans on tide-swept ciraclittoral rock
Published date 2015-03This variant is typically found on wave-exposed circalittoral bedrock and boulders, on steep slopes and upper faces in moderate tidal streams. This species-rich biotope is characterised by a dense spo...
