Site details


Site description: Two islands in the Ría de Vigo estuary with extensive areas of cliff. The vegetation is mainly scrub and Pinus and Eucalyptus plantations. The main human activities are tourism and recreation.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: This is an important site for breeding seabirds with one of the largest colonies of Larus cachinnans in the world and of Phalacrocorax aristotelis in Europe.
Delineation rationale: 2012-12-17 (BL Secretariat): the original site boundary has been clipped to the coastline (hi-res GIS) to avoid overlap with the new marine IBA identified adjacent to this site in October 2012; site area has been correspondingly changed from 433 ha to 467 ha.
