| Definition | Exposed and moderately exposed kelp park in some areas is heavily grazed by the urchin Echinus esculentus. The rock surface lacks any significant turf of foliose seaweeds and generally looks bare, though it is covered by coralline algal crusts and some grazing-resistant species such as the keel worm Pomatoceros triqueter. The kelp stipes may or may not be grazed; in the most extremely grazed areas, they too are devoid of epiphytic seaweeds. More usually, however, the stipes offer a refuge from grazing, and are characterised by dense turfs of red seaweeds, especially Phycodrys rubens, Palmaria palmata, Membranoptera alata and Delesseria sanguinea. The fauna within a grazed kelp park is also relatively sparse, though some species will survive in cracks and crevices, or other areas that are protected from grazing. This biotope generally occurs below a grazed kelp forest (MIR.LhypGz.Ft). | |
