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 |
|---|---|---|---|---|
| Macaroni Penguin Eudyptes chrysolophus | VU | breeding (2015–2021) | min 150 birds | A1 |
| Macaroni Penguin Eudyptes chrysolophus | VU | breeding (2007) | 35,000 pairs | A1 |
| Southern Rockhopper Penguin Eudyptes chrysocome | VU | breeding (2015–2021) | min 500 birds | A1 |
| Southern Rockhopper Penguin Eudyptes chrysocome | VU | breeding (2006–2007) | 134,000 pairs | A1, A2, A4 |
| Southern Giant Petrel Macronectes giganteus | LC | breeding (2007) | 1,000 nests | A4 |
| Chilean Skua Catharacta chilensis | LC | breeding (2015–2021) | 100 birds | A4 |
| Striated Caracara Phalcoboenus australis | NT | breeding (2008) | 150 birds | A2, B1a |

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. The most recent assessment (2015) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2015 | good | low | very low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | medium | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Coastal/Supratidal | - | good (>90%) | good |
| Grassland | - | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| No known threats | past (and unlikely to return) and no longer limiting | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Little/none of area covered (<10%) | No management planning has taken place | Very little or no conservation action taking place | very low |
