South Arran NCMPA - designation documents

Some of Scotland’s most important and productive seabed habitats are protected by the South Arran Nature Conservation MPA designation.

South Arran summary front cover

Designated for its diversity of animals and plants, the site features maerl beds, kelp and seaweed communities, and burrowed mud. What is possibly the Clyde’s largest seagrass bed is also found here.

Covering over 250 square kilometres, including the Lamlash Bay No Take Zone, the South Arran NCMPA will provide long-term support for our seas.
