Site description Situated 4 km off the north coast of County Dublin, this site includes Lambay Island and surrounding waters. About a third of the island on the lower western shore comprises managed pasture, with much of the rest being used as rough grazing for cattle and sheep.

Key Biodiversity Lambay Island is internationally important for breeding seabirds. Several other seabird species breed in nationally important numbers, including Fulmarus glacialis (573 pairs, 1995), Phalacrocorax carbo (605 pairs, 1995) and Rissa tridactyla (5,102 pairs, 1995). This site also supports nationally important numbers of wintering Anser anser (437 birds, 1995) and is one of the top sites for this species in Ireland.
