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 |
|---|---|---|---|---|
| Humboldt Penguin Spheniscus humboldti | VU | breeding (2003) | 7,000 pairs | A1, A4 |
| Humboldt Penguin Spheniscus humboldti | VU | resident (2011–2021) | max 1,563 birds | A1, A4 |
| Peruvian Diving-petrel Pelecanoides garnotii | NT | non-breeding (2003) | 65 birds | B1a |
| Peruvian Diving-petrel Pelecanoides garnotii | NT | resident (2015–2021) | min 150 birds | 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 | high | 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 |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | likely in short term (<4 years) | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | high |
| Human intrusions and disturbance | past (and unlikely to return) and no longer limiting | whole of population/area (>90%) | moderate decline (10–30% 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 plan exists, but the management planning process has begun | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
