The site was identified as internationally important for bird conservation in 2014 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 |
---|---|---|---|---|
Australasian Bittern Botaurus poiciloptilus | VU | resident (-) | min 6 | A1 |
Black Stilt Himantopus novaezelandiae | CR | breeding (2009–2013) | max 2 birds | A1 |
Wrybill Anarhynchus frontalis | VU | non-breeding (2009–2013) | 349–701 birds | A1, A4i |
Black-billed Gull Larus bulleri | NT | breeding (-) | 311–530 pairs | A1, A4i |
Black-fronted Tern Chlidonias albostriatus | EN | non-breeding (2006–2015) | 28–54 birds | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2014) is shown below.
