CR.FCR.FouFa Circalittoral fouling faunal communities
Published date 2015-03This biotope complex contains two biotopes which, although have different physical habitat characteristics, share the fact that they colonise new areas of artificial substrata relatively quickly. The ...
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...
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...
IR Infralittoral rock (and other hard substrata)
Published date 2015-03Infralittoral rock includes habitats of bedrock, boulders and cobbles which occur in the shallow subtidal zone and typically support seaweed communities. The upper limit is marked by the top of the ke...
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 ...
LR.HLR.FT.AscT Ascophyllum nodosum, sponges and ascidians on tide-swept mid eulittoral rock
Published date 2015-03Very sheltered to extremely sheltered areas of mid eulittoral rock that are subject to strong to moderate tidal streams, such as the narrows in sea lochs, and characterised by the wrack Ascophyllum no...
