Other Site Characteristics

Clare Island lies 5km from the mainland. The geology of the site is diverse, consisting of Dalradian sandstones and shore Carboniferous sandstones, shales and conglomerates and a variety of silurian rocks. The dominant feature of the site is a high ridge that attains a height of 462km at Knockmore mountain and forms precipitous sea cliffs (400m high) along the northern side of the island. Vegetated sea cliff, rocky slope and heathy vegetation dominate this area of the site. Elsewhere in the site, areas of lower cliffs, shingle and salt marsh are found.

4.2 Quality and importance

The site holds fine examples of the Annex I Habitats, vegetated sea cliffs, siliceous rocky and calcareous rocky slopes. These habitats support interesting alpine vegetation communities and include a number of Red Data Book species. In addition Falco peregrinus, a species listed on Annex I of the EU Birds Directive occur on the site. The site supports important colonies of seabirds.
