Preferred label [Fucus serratus] on full salinity sheltered lower eulittoral rock
Definition Sheltered lower eulittoral rock subject to fully marine conditions characterised by a dense canopy of the wrack [Fucus serratus]. There is a wide range of associated species found on the surface of the rock underneath the canopy, including the barnacle [Semibalanus balanoides], limpets [Patella vulgata], winkles [Littorina littorea], and even mussels [Mytilus edulis] can be present in cracks and crevices. These species are usually found in higher abundance further up on the shore. There may also be a number of other seaweeds present, including the red [Corallina officinalis] and [Mastocarpus stellatus], the wrack [Fucus vesiculosus] and the green [Enteromorpha intestinalis], [Ulva lactuca] or [Cladophora rupestris], though these usually are present in low numbers if present at all. The sponge [Halichondria panicea] can be present underneath the [F. serratus] canopy in moist cracks or minor overhangs. Polychaetes such as [Pomatoceros triqueter] and [Spirorbis] spp. are present in their white calcareous tubes on the rock. Situation: This biotope usually occurs immediately below a [Fucus vesiculosus]-barnacle mosaic (FvesB) on moderately exposed shores or a dense canopy of [F. vesiculosus] (Fves) or [Ascophyllum nodosum] (Asc.FS) on sheltered shores; consequently low densities of these species (typically less than Frequent) may also occur in this biotope. The sub littoral fringe below on moderately exposed shores is dominated by the kelp [Laminaria digitata] (Ldig; Ldig.LdigBo), while the kelp [Laminaria saccharina] may co-dominate on sheltered shores (Lsac.Ldig; Lsac.Ft). Temporal variation: Fluctuations from year to year in the abundance of the [F. serratus] and the red seaweeds due to e.g. severe storms may convert this biotope into either Fser.R or into a red seaweed dominated biotope on moderately exposed shores.
