Annex I habitats that are a primary reason for selection of this site

1170 Reefs
This well-defined, discrete area encompasses a complex group of islands, sounds and inlets characterised by some of the strongest tidal streams in the UK. The area is moderately exposed to wave action with very sheltered pockets enclosed by islands and skerries. Reefs extend from the shallow depths between the islands and mainland into depths of over 200 m, in many places close inshore. The varied physical environment is reflected in the variety of reef types and associated communities and species, which are amongst the most diverse in both the UK and Europe. These range from those characteristic of conditions sheltered from waves and currents, to those influenced by extreme tidal streams. A rapid transition in communities occurs with the deceleration of the tidal streams. Species present include some which are normally characteristic of deeper water (the sponges Mycale lingua and Clathria barleii, and the featherstar Leptometra celtica), and others which are considered scarce (including the brown alga Desmarestia dresnayi). Many species occurring here have either a northern or southern-influenced distribution and reach their geographic limits in this area, for example, the southern cup-coral Caryophyllia inornata, the nationally scarce brittlestar Ophiopsila annulosa, and the northern bryozoans Bugula purpurotincta and Caberea ellisii.
