Concept: [Laminaria digitata] on moderately exposed sublittoral fringe bedrock in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A3.2111
Preferred label [Laminaria digitata] on moderately exposed sublittoral fringe bedrock
Definition Exposed to sheltered sublittoral fringe bedrock dominated by a dense canopy of [Laminaria digitata], often with a wide range of filamentous and foliose red seaweeds beneath. The most frequently occurring red seaweeds are [Palmaria palmata], [Corallina officinalis], [Mastocarpus stellatus], [Chondrus crispus, Lomentaria articulata] and [Membranoptera alata]. Generally the rocky substratum is covered by encrusting coralline algae, on which occasional limpets [Patella vulgata] and topshells [Gibbula cineraria] graze. A wide variety of fauna occurs, some of the most commonly occurring species being the sponge [Halichondria panicea] and the tube-building polychaete [Pomatoceros triqueter]. Kelp holdfasts provide a refuge for a varied assemblage of species such as sponges and the limpet [Helcion pellucidum], while encrusting bryozoans such as [Electra pilosa] more often are found on the fronds of foliose red seaweeds. Solitary ascidians may be locally abundant where overhanging or vertical rock occurs, while the hydroid [Dynamena pumila] can be abundant on [Fucus serratus] and [Laminaria] sp. fronds. On exposed, wave-surged shores, the robust red seaweeds [M. stellatus], [C. crispus] and [C. officinalis] can form a dense turf beneath the kelp along with the occasional green seaweed [Ulva lactuca]. Similarly on such shores the mussel [Mytilus edulis] can occur in extremely dense aggregations on the rock, beneath the kelp canopy. Situation: This biotope is usually found on the extreme low shore below the [Fucus serratus] zone (Fser) and above the truly sublittoral [Laminaria hyperborea] zone (Lhyp).
