The site was identified as important in 2010 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):Species | Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Magellanic Penguin Spheniscus magellanicus | LC | breeding | 2007 | 1,706 breeding pairs | A1 |
Sooty Shearwater Ardenna grisea | NT | breeding | 2007 | 4,000,000 breeding pairs | A1, A4ii |
A4iii Species group - seabirds | n/a | breeding | 1984 | 2,500,000-4,999,999 individuals | A4iii |
The current IUCN Red List category (shown above) may differ from that which was valid at the time of IBA criteria assessment (2010).
