Data Zone
The site was identified as important in 2012 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Sooty Tern Onychoprion fuscatus | LC | breeding | 1974 | 400,000 individuals | A4i |
| A4iii Species group - waterbirds | n/a | breeding | 1974 | 404,050 individuals | A4iii |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2012) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2012) is shown below.

| Whole area of site (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity | high |
