| Definition | Very to extremely sheltered sublittoral fringe and infralittoral bedrock, boulders and cobbles may be characterised by a dense canopy of Laminaria saccharina. In such sheltered conditions a distinct sublittoral fringe is not always apparent and this biotope often extends from below the Fucus serratus zone (SLR.Fserr) into the upper infralittoral zone, though there may be a mixed Laminaria saccharina and Laminaria digitata (SIR.Lsac.Ldig) zone between. This biotope has a relatively low species richness due to heavy siltation of the habitat and the lack of light penetrating through the dense kelp canopy. Only a few species of red seaweed, such as Ceramium spp., Chondrus crispus and Palmaria palmata may be present (compare with SIR.Lsac.Ldig), whilst limpets, barnacles and littorinids are rare. Saddle oysters Pododesmus patelliformis and chitons may occur in high abundance at some sites. In very sheltered but tide-swept habitats, the L. saccharina tends to be replaced by L. digitata (MIR.Ldig.T) in the sublittoral fringe. | |
