Preferred label [Sabellaria spinulosa] with kelp and red seaweeds on sand-influenced infralittoral rock
Definition [Laminaria hyperborea] kelp forest on shallow infralittoral bedrock and boulders characterised by encrustations of [Sabellaria spinulosa] tubes which cover much of the rock, together with sand-tolerant red seaweeds such as [Phyllophora pseudoceranoides, Dilsea carnosa] and [Polysiphonia elongata] and [Polysiphonia fucoides]. Red seaweeds such as [Plocamium cartilagineum] and [Delesseria sanguinea] may also be found beneath the kelp canopy, although typically low in abundance. They can be colonised by the ascidian [Botryllus schlosseri]. The cowrie [Trivia arctica] can also be found here. Much of the available rock is covered with encrusting coralline algae together with patches of the encrusting sponge [Halichondria panicea] and the anthozoan [Urticina felina]. More mobile fauna include the echinoderms [Asterias rubens, Henricia sanguinolenta, Echinus esculentus], and [Ophiothrix fragilis], the gastropod [Gibbula cineraria] and the hermit crab [Pagurus bernhardus]. The scouring effect of mobile sand adjacent to the rock maintains a reduced underflora and fauna compared to the association of species found in non-scoured kelp forests (Lhyp.Ft). Scour-resistant fauna such as the barnacle [Balanus crenatus] can be locally abundant on the rock, while the bivalve [Pododesmus patelliformis] can be found seeking shelter underneath the cobbles. Above the effect of scour, kelp stipes may be densely colonised by red seaweeds such as [Phycodrys rubens], [Palmaria palmata] and [Membranoptera alata], together with some sponges and ascidians. Situation: This biotope is found in the sand-laden waters of north-east England in conditions in which [S. spinulosa] is able to thrive. Nearby circalittoral rock is often also dominated by [S. spinulosa] (Sspi) but lacks the kelp and red seaweeds. As this biotope is not commonly recorded in the UK there is a scarcity of information relating to the surrounding biotopes.
