Data Zone
The site was identified as internationally important for bird conservation in 2024 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 |
|---|---|---|---|---|
| Atlantic Yellow-nosed Albatross Thalassarche chlororhynchos | EN | non-breeding (2018) | min 50 birds | A1 |
| Trindade Petrel Pterodroma arminjoniana | VU | unknown (2018) | min 50 birds | A1, A4 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2024. The most recent assessment (2024) is shown below.
