Other Site Characteristics

Roaninish is situated in the outer part of Gweebarra Bay, approximately 3 km north-west of Dunmore Head. The site comprises a tight group of small, flat, low-lying islets surrounded by extensive intertidal rocks. The highest point is 9 metres above sea level. The site includes the surrounding seas to a distance of 200 m, where seabirds forage, bathe and socialise. The main island supports lush maritime grassland and has two small ponds with some aquatic species.

4.2 Quality and importance

Roaninish is an important breeding site for seabird species. Of particular note is a long-established colony of Hydrobates pelagicus, which is of regional importance. Terns have long been associated with the island, but nowadays only Sterna paradisaea breeds in low numbers. Other seabirds which breed are Phalacrocorax carbo (recently established), Phalacrocorax aristotelis, Larus argentatus, Larus marinus and Cepphus grylle. The Larus argentatus population is of national importance. Somateria mollissima, a localised breeding species in Ireland, nests in substantial numbers on the islands. The site is also of importance as it provides feeding and refuge for a wintering flock of Branta leucopsis which at times exceeds the threshold for international importance.
