SS.SSa.IFiSa.ScupHyd Sertularia cupressina and Hydrallmania falcata on tide-swept sublittoral sand with cobbles or pebbles.
Published date 2015-03Shallow sands with cobbles and pebbles, exposed to strong tidal streams, with conspicuous colonies of hydroids, particularly Hydrallmania falcata and to a lesser extent Sertularia cupressina and S. ar...
SS.SCS.ICS Infralittoral coarse sediment
Published date 2015-03Moderately exposed habitats with coarse sand, gravelly sand, shingle and gravel in the infralittoral, are subject to disturbance by tidal steams and wave action. Such habitats found on the open coast ...
IR.MIR.KT.FilRVS Filamentous red seaweeds, sponges and Balanus crenatus on tide-swept variable-salinity infralittoral rock
Published date 2015-03Tide-swept infralittoral rock subject to variable salinity and turbid waters occurs in the mid to upper reaches of the rias of south-west Britain, where riverine freshwater input reduces the salinity....
LS.LSa.MoSa.AmSco.Pon Pontocrates arenarius in littoral mobile sand
Published date 2015-03Mainly on the mid and lower shore on wave-exposed or moderately wave-exposed coasts of medium and fine sand, sometimes with a fraction of coarse sand, which remains damp throughout the tidal cycle and...
LR.FLR.Eph.UlvPor Porphyra purpurea and Ulva spp. on sand-scoured mid or lower eulittoral rock
Published date 2015-03Exposed and moderately exposed mid-shore bedrock and boulders occurring adjacent to areas of sand which significantly affects the rock. As a consequence of sand-abrasion, wracks such as Fucus vesiculo...
LR.FLR.CvOv.SpR Sponges and shade-tolerant red seaweeds on overhanging lower eulittoral bedrock and in cave entrances
Published date 2015-03Overhanging shaded bedrock on the open lower shore and at the entrance to inner reaches of caves (where light availability permits), which is not subject to appreciable wave-surge, characterised by a ...
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...
IR.HIR.KSed.XKScrR Mixed kelps with scour-tolerant and opportunistic foliose red seaweeds on scoured or sand-covered infralittoral rock
Published date 2015-03Bedrock and boulders, often in tide-swept areas, that are subject to scouring or periodic burial by sand, characterised by a canopy of mixed kelps such as Saccharina latissima, Laminaria hyperborea an...
LS.LCS.Sh.Ech Echinogammarus incertae sedis planicrurus in mid shore well-sorted gravel or coarse sand
Published date 2015-03Shores of well-sorted gravel with a predominant particle size of 4.0 mm but ranging between 3 and 6 mm support dense populations of the amphipod Echinogammarus incertae sedis planicrurus. Material fin...
IR.LIR.IFaVS Faunal communities on variable or reduced salinity infralittoral rock
Published date 2015-03Shallow subtidal rocky habitats which support faunal-dominated communities, with seaweed communities only poorly developed or absent. In some sealochs dense mussel Mytilus edulis beds (MytRS) develop ...
