Isles of Scilly

image: SPA location map 


The Isles of Scilly form an archipelago of over 200 low-lying granite islands and rocks situated in the South-West Approaches45 km south-west of Land's End at the extreme south-west of England. The islands included within the SPA support a breeding seabird assemblage of European importance. The isolated nature of the islands and rocks, together with their low levels of disturbance and predation, makes them particularly suitable for nesting seabirds such as Storm Petrel Hydrobates pelagicus and Lesser Black-backed Gull Larus fuscus. It should be noted that the SPA boundary only encompasses those areas used for nesting. The vast majority of the feeding areas used by the seabirds are marine waters outside the SPA.

Many designated sites are on private land: the listing of a site in these pages does not imply any right of public access.
Note that sites selected for waterbird species on the basis of their occurrence in the breeding, passage or winter periods also provide legal protection for these species when they occur at other times of the year.
