Data Zone
The site was identified as internationally important for bird conservation in 1999 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 |
|---|---|---|---|---|
| Masked Finfoot Heliopais personatus | CR | non-breeding (1984) | present | A1 |
| Milky Stork Mycteria cinerea | EN | breeding (1984) | 2–50 birds | A1, A4i |
| Purple Heron Ardea purpurea | LC | breeding (1987–1998) | present | A4i |
| Christmas Island Frigatebird Fregata andrewsi | VU | non-breeding (1987–1998) | present | A1 |
| A4iii Species group - waterbirds | n/a | breeding (1988) | min 20,000 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2012) is shown below.
