Data Zone
The site was identified as important 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Atlantic Yellow-nosed Albatross Thalassarche chlororhynchos | EN | non-breeding | 2018 | min 50 individuals | A1 |
| Trindade Petrel Pterodroma arminjoniana | VU | unknown | 2018 | min 50 individuals | A1, A4 |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2024) may differ.
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.
