Status: Designated

Description

Site overview

This is a large, low-lying island in the north-east of the Orkney archipelago. Around the island are several reefs that in turn provide a habitat for dense forests of kelp. There are large, dense brittlestar populations here, along with horse mussels. The island is also home to the largest group of Harbour seals at any site in Scotland. They make up just over 4% of the total UK Harbour seal population. The kelp beds are important feeding areas for the seals, and the colony is linked to a very large surrounding population in the Orkney archipelago.
