Clyde Sea Sill, the most southerly MPA, is designated for black guillemot, circalittoral sand & coarse sediment communities, and fronts.
The cliffs of Sanda Island are an existing SSSI for breeding birds, and black guillemot breeding areas rely on the continuing productivity of rich feeding grounds such as the Clyde Sea Sill nearby. The seabed contains areas of coarse sandy sediment. Clam shells and polychaete worms live beneath the sediment while fish, starfish, brittle stars and hermit crabs roam the surface looking for food.
The current conservation objective is to conserve the protected features of this MPA.
More detail on the designation is available from the SNH website.
The final Business and Regulatory Impact Assessment for this MPA is available to view.
