L
Dominated by animals with no foliose algae but encrusting Rhodophycota patchy in grazed areas. The part of the circalittoral subzone on hard substrata below the maximum depth limit of foliose algae (based on Hiscock, 1985). +
The part of the infralittoral subzone which, on hard substrata, supports scattered kelp plants (a kelp park) or from which kelps are absent altogether and the seabed is dominated by foliose red and brown algae. It may be difficult to distinguish the lower infralittoral where grazing pressure prevents the establishment of foliose algae (based on Hiscock, 1985). +
The lower part of the shore only exposed (emersed) at the lowest part of the tide. +
The bottom of the littoral fringe. In the UK, characterized by he ''Pelvetia/Porphyra'' belt with patchy ''Verrucaria maura'' and ''Fucus spiralis'' (on sheltered shores). ''Verrucaria mucosa'' present above the main barnacle population. May also include salt marsh species on shale/pebbles in shelter (Hiscock, 1996). +
M
Species that comprise indicators or components of indicators for the Marine Strategy Framework Directive (http://ec.europa.eu/environment/marine/eu-coast-and-marine-policy/marine-strategy-framework-directive/index_en.htm), with emphasis on Descriptors 1, 2, 3, 4 and 6. +
Macroalgal surfaces, such as kelps and fucoids. +
Individual organisms with a mean body size between 2.0 and 200 mm. +
