SPA description
(information as published 2001)
North Rona and Sula Sgeir
The two small and remote islands of North Rona and Sula Sgeir
lie in the North Atlantic about 65 km from the island of Lewis in
the Outer Hebrides off the north-west coast of Scotland. Sula Sgeir
is about 15 km west of the far larger North Rona. North Rona is
well covered by peat or soil and is vegetated with maritime
grassland. Sula Sgeir is subject to severe erosive pressure from
sea spray and seabirds and has little soil or vegetation. The
islands provide strategically placed nesting localities for large
numbers of seabirds which feed in the waters off the north coast of
Scotland away from the SPA. They hold a diverse assemblage of
species including large numbers of petrels, auks, gulls and Gannet
Morus bassanus. It is one of only seven known nesting
localities in the EU for Leach's Petrel Oceanodroma
leucorhoa.

their occurrence in the breeding, passage or winter periods also
provide legal protection for these species when they occur at other
