Data Zone
The site was identified as internationally important for bird conservation in 2022 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 |
|---|---|---|---|---|
| Black Skimmer Rynchops niger | LC | non-breeding (2020–2022) | 1,000–4,000 birds | A4, B3a |
| Olrog's Gull Larus atlanticus | NT | non-breeding (2016) | 125 birds | B1a, B3a |
| Common Tern Sterna hirundo | LC | non-breeding (2017) | 20,000–30,000 birds | B3a |
| A4iii Species group - waterbirds | n/a | non-breeding (2016–2022) | 21,125–34,125 birds | B3b |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. The most recent assessment (2019) is shown below.

| Energy production and mining | happening now | some of population/area (10–49%) | rapid decline (>30% over 3 generations) | high |
| Climate change and severe weather | happening now | few individuals/small area (<10%) | rapid decline (>30% over 3 generations) | low |
