Glannau Aberdaron and Ynys Enlli / Aberdaron Coast and Bardsey Island

image: SPA location map 

 

Glannau Aberdaron and Ynys Enlli, or Aberdaron Coast and Bardsey Island, is located at the tip of the Lleyn Peninsula in north-west Wales. The site consists of the island of Bardsey (Ynys Enlli) and part of the tip of the Lleyn Peninsula, together with two smaller islands – the Gwylans. The coastline is rocky, with many crags, screes and low cliffs. The Aberdaron coast consists of a series of heather-covered hills rising to about 190 m, separated by valleys occupied by pastures. The maritime heaths are dominated by Heather Calluna vulgaris, Bell Heather Erica cinerea and Western Gorse Ulex gallii and are exposed to strong westerly winds. The Mountain on Ynys Enlli has similar heathland to the mainland, whilst the sheltered screes on the north-east of the island have a rich fern and bryophyte flora. The site supports a resident population of Chough Pyrrhocorax pyrrhocorax which depend on the diverse mix of habitats present and their low-intensity agricultural management. The site also holds a large breeding colony of Manx Shearwaters Puffinus p. puffinus. The shearwaters feed outside the SPA in the nearby waters as well as more distantly in the Irish Sea.
