Coquet Island is located 1 km off the coast of Northumberland in north-east England. It is a small, flat-topped island with a plateau extent of c. 7 ha. The island is surrounded by low sandstone cliffs and a broad rock platform at low tide, partly the result of former stone quarrying. The peaty soil of the plateau supports short turf grassland, although where nutrient input from seabird colonies is greatest, there are dense stands of taller species, including nettlesUrtica spp. These provide cover for some of the nesting terns. The island is of importance for a range of breeding seabirds, including four species of terns, auks and gulls. The seabirds feed outside the SPA in the nearby waters, as well as more distantly in the North Sea.
