IBA Justification

The site was identified as important in 2009 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Little Penguin Eudyptula minor LC breeding 1978-1997 16,522 breeding pairs A4ii
Fairy Prion Pachyptila turtur LC breeding 1978-1997 27,020 breeding pairs A4ii
