Preferred label [Laminaria hyperborea] on tide-swept infralittoral mixed substrata
Definition Wave-exposed through to wave-sheltered, tide-swept infralittoral mixed substrata with [Laminaria hyperborea] forest/park and other kelp species such as [Laminaria saccharina]. The rich under-storey and stipe flora is characterised by foliose seaweeds including the brown algae [Dictyota dichotoma]. The kelp stipes support epiphytes such as [Cryptopleura ramosa], [Callophyllis laciniata] and [Phycodrys rubens]. At some sites, instead of being covered by red seaweeds, the kelp stipes are heavily encrusted by the ascidians [Botryllus schlosseri] and the bryozoan [Alcyonidium diaphanum]. Epilithic seaweeds such as [Desmerestia aculeata], [Odonthalia dentate], [Delesseria sanguinea], [Plocamium cartilagineum], [Callophyllis laciniata], and crustose seaweeds commonly occur beneath the kelp. The kelp fronds are often covered with growths of the hydroid [Obelia geniculata] or the bryozoan [Membranipora membranacea]. On the rock surface, a rich fauna comprising anthozoans such as [Alcyonium digitatum] and [Urticina felina], colonial ascidians such as [Clavelina lepadiformis] and the calcareous tubeworm [Pomatoceros triqueter] occurs. More mobile species include the gastropods [Gibulla cineria] and [Calliostoma zizyphinum], the crab [Cancer pagurus] and the echinoderms [Crossaster papposus], [Henricia oculata], [Asterias rubens] and [Echinus esculentus]. Two variants are described; tide-swept kelp forest on upper infralittoral mixed substrata (LhypTX.Ft) and tide-swept kelp park on lower infralittoral mixed substrata (LhypTX.Pk).
