IBA Justification

The site was identified as internationally important for bird conservation in 2009 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
Pied Oystercatcher Haematopus longirostris LC resident (1999–2008) 18–224 birds A4i
