SPA description

Mousa is a small island located off the east coast of the south part of the Shetland mainland in northern Scotland. It is a low grassy island, reaching only 55 m above sea level, and is dominated by acidic grassland. There is also some maritime grassland and heathland on the exposed south-west coast. Mousa has a few freshwater lochs and, in the south-east, tidal pools. The island is of importance as a breeding site for seabirds, notably the largest colony of Storm Petrel Hydrobates pelagicus in Shetland as well as Arctic Tern Sterna paradisaea. The seabirds nesting on Mousa feed outside the SPA in surrounding waters, as well as further away.
