| Definition | Moderately exposed upper infralittoral bedrock and boulders characterised by a dense forest of Laminaria hyperborea with dense foliose red seaweeds beneath (such as Plocamium cartilagineum, Cryptopleura ramosa and Delesseria sanguinea). The rock surface is generally covered by encrusting coralline algae, while cracks and crevices are filled with the sponge Halichondria panicea. Small vertical surfaces within the kelp forest generally lack kelp plants, instead being characterised by foliose red seaweeds, Alcyonium digitatum, Caryophyllia smithii and solitary and colonial ascidians. Kelp stipes are usually covered in a rich mixture of red seaweeds including Palmaria palmata, Phycodrys rubens and Membranoptera alata, and sometimes small kelp plants. This biotope generally occurs below the sublittoral fringe L. digitata zone (MIR.Ldig). Where urchins are present, the abundance of red seaweeds may be much reduced (though not the species richness?) (see MIR.LhypGz.Ft). | |
