Concept: [Lithothamnion glaciale] maerl beds in tide-swept variable salinity infralittoral gravel in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A5.512
Preferred label [Lithothamnion glaciale] maerl beds in tide-swept variable salinity infralittoral gravel
Definition Upper infralittoral tide-swept channels of coarse sediment in full or variable salinity conditions support distinctive beds of [Lithothamnion glaciale] maerl 'rhodoliths'. [Phymatolithon calcareum] may also be present as a more minor maerl component. Associated fauna and flora may include species found in other types of maerl beds (and elsewhere), e.g. [Pomatoceros triqueter], [Cerianthus lloydii], [Sabella pavonina], [Chaetopterus variopedatus], [Lanice conchilega], [Mya truncata], [Plocamium cartilagineum] and [Phycodrys rubens]. Lgla, however, also has a fauna that reflects the slightly reduced salinity conditions, e.g. [Psammechinus miliaris] is often present in high numbers along with other grazers such as chitons and [Tectura] spp. [Hyas araneus], [Ophiothrix fragilis], [Ophiocomina nigra] and the brown seaweed [Dictyota dichotoma] are also typically present at sites. In Scottish lagoons this biotope may show considerable variation but the community falls within the broad description defined here. Situation: This biotope can often be found at the upper end of Scottish sealochs where the variable salinity of the habitat may not be immediately obvious.
