| Preferred label | Sparse [Laminaria hyperborea] and dense [Paracentrotus lividus] on exposed infralittoral limestone |
| Definition | This biotope is known from only one location, the Aran Islands, Co. Galway. Here, a limestone platform between 3 m and 6 m of depth is dominated by a dense population of the urchin [Paracentrotus lividus], which heavily graze and burrow into the soft limestone. So intense is the grazing pressure that the rock appears completely bare, except for a coralline algal crust and occasional [Laminaria hyperborea] and [Saccorhiza polyschides]. The anthozoans [Sagartia elegans] and [Corynactis viridis] are also present, though at low abundance. The grazed kelp also extends deeper to 20 to 25 m further offshore. (Only one CB record within this biotope). Situation: This rare biotope has only been recorded from one location and the neighbouring biotopes were not fully surveyed. In deeper water (30-40m) there is PhaAxi. |
