Preferred label [Laminaria hyperborea] park with hydroids, bryozoans and sponges on tide-swept lower infralittoral rock
Definition Exposed to moderately wave-exposed, strongly tide-swept, rock with [Laminaria hyperborea] park characterised by a rich under-storey and stipe flora of foliose seaweeds such as [Phycodrys rubens], [Plocamium cartilagineum], [Hypoglossum hypoglossoides, Kallymenia reniformis], [Cryptopleura ramosa] and [Delesseria sanguinea]. The red seaweed [Heterosiphonia plumosa] can be present. The foliose brown seaweed [Dictyota dichotoma] and coralline crust are often present as well. Amongst the red seaweeds is a rich fauna comprising sponges ([Pachymatisma johnstonia], [Stelligera rigida], [Esperiopsis fucorum] and [Dysidea fragilis]), anthozoans ([Alcyonium digitatum] and [Caryophyllia smithii]), hydroids ([Aglaophenia pluma] and [Nemertesia antennina]), colonial ascidians ([Clavelina lepadiformis] and [Morchellium argus]) and bryozoans such as [Electra pilosa]. Both the flora and fauna of this biotope are similar to the wave exposed kelp park (LhypR.Pk), but LhypT.Pk has a greater faunal component including the barnacle [Balanus crenatus], the echinoderm [Asterias rubens] and the crab [Necora puber]. Situation: This biotope generally occurs below a tide-swept [L. hyperborea] kelp forest (LhypT.Ft). As this biotope occurs over such a range of wave exposures a variety of circalittoral biotopes can occur beneath it: for example, Exposed, tide-swept rock (FaT) or moderately exposed tide-swept rock (EcCr).
