Data Zone
The site was identified as important 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Humboldt Penguin Spheniscus humboldti | VU | breeding | 2003 | 7,000 breeding pairs | A1, A4 |
| Humboldt Penguin Spheniscus humboldti | VU | resident | 2011-2021 | max 1,563 individuals | A1, A4 |
| Peruvian Diving-petrel Pelecanoides garnotii | NT | non-breeding | 2003 | 65 individuals | B1a |
| Peruvian Diving-petrel Pelecanoides garnotii | NT | resident | 2015-2021 | min 150 individuals | B1a |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2022) may differ.
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 | favourable | 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%) | favourable |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | likely in short term (within 4 years) | whole area/population (>90%) | slow but significant deterioration | high |
| Human intrusions and disturbance | past (and unlikely to return) and no longer limiting | whole area/population (>90%) | moderate to rapid deterioration | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Protected areas | Management plan | Other action | Result |
| Little/none of site 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 |
| Year | Protected Area | Designation | % overlap with IBA |
