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...
LS.LBR.LMus.Myt.Sa Mytilus edulis beds on littoral sand
Published date 2015-03This sub-biotope occurs on mid to lower shore sand and muddy sand. Mussels Mytilus edulis grow attached to shell debris and live cockles Cerastoderma edule, forming patches of mussels on consolidated ...
SS.SMu.ISaMu Infralittoral sandy mud
Published date 2015-03Infralittoral, cohesive sandy mud, typically with over 20% silt/clay, in depths of less than 15-20 m. This habitat is generally found in sheltered bays or marine inlets and along sheltered areas of op...
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...
CR.MCR.EcCr.FaAlCr.Flu Flustra foliacea on slightly scoured silty circalittoral rock
Published date 2015-03This variant is typically found on the upper faces of moderately wave-exposed circalittoral bedrock or boulders subjected to moderately strong tidal streams. These rocky patches may be interspersed wi...
CR.MCR.CSab.Sspi.ByB Sabellaria spinulosa with a bryozoan turf and barnacles on silty turbid circalittoral rock
Published date 2015-03This variant is typically found encrusting the upper faces of exposed and moderately exposed circalittoral rock and mixed substrata, subject to strong and moderately strong currents and high turbidity...
CR.MCR.EcCr.CarSp.PenPcom Caryophyllia smithii and sponges with Pentapora foliacea, Porella compressa and crustose communities on wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on the upper faces and vertical sides of wave-exposed bedrock or boulders subject to moderately strong to weak tidal streams. The fauna is often sparse with the frequen...
