IR.HIR.KFaR.LhypR.Ft Laminaria hyperborea forest with dense foliose red seaweeds on exposed upper infralittoral rock
Published date 2015-03Very exposed to exposed upper infralittoral bedrock or large boulders characterised by a dense forest of the kelp Laminaria hyperborea. On the rock surface beneath the kelp canopy is a dense turf of r...
SS.SCS.CCS.Blan Branchiostoma lanceolatum in circalittoral coarse sand with shell gravel
Published date 2015-03Gravel and coarse sand with shell gravel often contains communities of robust venerid bivalves (SS.SCS.CCS.MedLumVen). Shallower examples, such as the biotope presented here, may support a significant...
SS.SMu.SMuVS.LhofTtub Limnodrilus hoffmeisteri, Tubifex tubifex and Gammarus spp. in low salinity infralittoral muddy sediment
Published date 2015-03Upper estuary muddy sediments with very low fluctuating salinity, characterised by the oligochaetes Limnodrilus hoffmeisteri and Tubifex tubifex. Other taxa may include Marenzelleria wireni, Gammarus ...
IR.HIR.KFaR Kelp with cushion fauna and/or foliose red seaweeds
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 ...
IR.FIR.SG.FoSwCC Foliose seaweeds and coralline crusts in surge gully entrances
Published date 2015-03This biotope is found on steep wave-surged entrances to gullies and caves and on unstable boulders in the entrance to caves and gullies. The rock may be abraded by the movement of the boulders and cob...
CR.MCR.EcCr.CarSwi.Aglo Caryophyllia smithii, Swiftia pallida and Alcyonium glomeratum on wave-sheltered circalittoral rock
Published date 2015-03This variant typically occurs on sheltered, ridged, circalittoral bedrock or boulders subject to only weak tidal streams, but may be found in somewhat more exposed conditions. It is found in water dep...
LS.LSa.MuSa.MacAre Macoma balthica and Arenicola marina in littoral muddy sand
Published date 2015-03Muddy sand or fine sand, often occurring as extensive intertidal flats both on open coasts and in marine inlets. The sediment is often compacted, with a rippled surface, areas of standing water, and g...
SS.SMp.SSgr Sublittoral seagrass beds
Published date 2015-03Beds of seagrass (Zostera subg. Zostera marina or Ruppia spp.) in shallow sublittoral sediments. These communities are generally found in extremely sheltered embayments, marine inlets, estuaries and l...
SS.SCS.SCSVS Sublittoral coarse sediment in variable salinity (estuaries)
Published date 2015-03Clean gravels that occur in the upper reaches of marine inlets, especially estuaries, where water movement is sufficiently strong to remove the silt content of the sediment. The habitat typically lack...
CR.HCR High energy circalittoral rock
Published date 2015-03This habitat complex occurs on extremely wave-exposed to exposed circalittoral bedrock and boulders subject to tidal streams ranging from strong to very strong. Typically found in tidal straits and na...
