Preferred label [Laminaria saccharina] park on very sheltered lower infralittoral rock
Definition Silty bedrock or boulders with a [Laminaria saccharina] park (often the cape-form). Beneath the canopy, the rock is covered by encrusting coralline algae, and the urchin [Echinus esculentus] is often present. Due to the amount of silt cover on the rock and the reduced light intensity beneath the broad-fronded kelp, only a few red seaweeds typically survive, the most common species being [Phycodrys rubens], [Delesseria sanguinea], [Bonnemaisonia] spp. and [Brongniartella byssoides]. The brown seaweeds [Dictyota dichotoma] and [Cutleria multifida] may be present in low abundance. Compared to the kelp forest zone above (Lsac.Ft) both the kelp and other seaweeds are sparse (Occasional). The most conspicuous animals are large solitary ascidians, particularly [Ascidia mentula] and [Ciona intestinalis], together with the smaller [Clavelina lepadiformis]. In general, the faunal component of this biotope is similar to other sheltered kelp biotopes and includes a variety of mobile crustaceans such [Carcinus maenas] and [Pagurus bernhardus], the keelworm [Pomatoceros] spp., terebellid worms, echinoderms [Asterias rubens], [Ophiothrix fragilis] and the featherstar [Antedon bifida]. The hydroid [Kirchenpauria pinnata], although only rare is often found in the kelp park along with the top shell [Gibbula cineraria] and the barnacle [Balanus crenatus]. Situation: [L. saccharina] park can be found below a similar forest (Lsac.Ft) where suitable hard substrata exist or on isolated rock exposures surrounded by sediment communities. It may also occur below a zone of mixed [Laminaria hyperborea] and [L. saccharina] forest (LhypLsac). [L. saccharina] can also form a band below [L. hyperborea] forest (Lhyp.Ft) where some shelter from wave-action is afforded with depth ([L. saccharina] is not tolerant of surge), or more likely where [L. hyperborea] has been grazed out (below Lhyp.GzFt) since [L. saccharina] grows far quicker than [L. hyperborea]. Where such a narrow band occurs it is generally less silted than that found below Lsac.Ft in much more sheltered conditions. A range of sheltered circalittoral biotopes may occur on any deeper rock below (e.g. AntAsH, AmenCio and ModHAs).
