The site was identified as internationally important for bird conservation in 2011 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
---|---|---|---|---|
European Storm-petrel Hydrobates pelagicus | LC | resident (2007) | 500–1,796 pairs | C6 |
Eurasian Spoonbill Platalea leucorodia | LC | passage (2009) | min 500 birds | A4i, B1i, C2 |
European Shag Gulosus aristotelis | LC | resident (2007) | 112 pairs | B3 |
Eurasian Curlew Numenius arquata | NT | winter (2010) | 79–278 birds | A1, C1 |
Peregrine Falcon Falco peregrinus | LC | resident (2008) | min 17 pairs | C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2008) is shown below.
