Data Zone
The site was identified as important in 2007 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 | - | 500,000-1,000,000 individuals | A4i |
| A4iii Species group - waterbirds | n/a | - | - | 500,100-1,000,500 individuals | A4iii |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2012) is shown below.
