LR.FLR.Lic Lichens or small green algae on supralittoral and littoral fringe rock
Published date 2015-03Lichen communities typically form a distinct zone or band in a 'splash' zone on most rocky shores. This splash zone occurs above the main intertidal zone (i.e. that subject to regular covering by the ...
LS Littoral sediment
Published date 2015-03Littoral sediment includes habitats of shingle (mobile cobbles and pebbles), gravel, sand and mud or any combination of these which occur in the intertidal zone. Littoral sediment is defined further u...
CR.MCR.SfR.Hia Hiatella-bored vertical sublittoral limestone rock
Published date 2015-03Moderately exposed vertical and overhanging soft rock (typically chalk), subject to moderately strong to weak tidal streams, bored by the rock-boring mollusc Hiatella arctica. As with other biotopes i...

SS.SCS.OCS Offshore circalittoral coarse sediment
Published date 2015-03Offshore (deep) circalittoral habitats with coarse sands and gravel or shell. This habitat may cover large areas of the offshore continental shelf although there is relatively little quantitative data...
SS.SCS.ICS.SLan Dense Lanice conchilega and other polychaetes in tide-swept infralittoral sand and mixed gravelly sand
Published date 2015-03Dense beds of Lanice conchilega occur in coarse to medium fine gravelly sand in the shallow sublittoral, where there are strong tidal streams or wave action. Several other species of polychaete also o...
