Haig Fras is an isolated, fully submarine bedrock outcrop located in the Celtic Sea, 95 km northwest of the Isles of Scilly. It is the only substantial area of rocky reef in the Celtic Sea beyond the coastal margin. It supports a variety of fauna ranging from jewel anemones and Devonshire cup coral near the peak of the outcrop to encrusting sponges, crinoids and ross coral towards the base of the rock (where boulders surround its edge) (Rees, 2000). There are four main habitat complexes; high energy circalittoral rock, moderate energy circalittoral rock, deep circalittoral coarse sediment and deep circalittoral sand. The total area of reef feature within the site boundary is approximately 175 km2. The rock type is granite, mostly smooth with occasional fissures. The rocky outcrop is approximately 45 km long and in one area rises to a peak which lies just 38 m beneath the sea surface (Rees, 2000, Barrio FrojŠn et al., 2015). The surrounding seabed is approximately 118 m deep, with small dispersed patches of rocky outcropping within circalittoral sand and coarse sediment (Barrio FrojŠn et al., 2015).
