Data Zone
The site was identified as internationally important for bird conservation in 2010 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 (2000) | 1,300 pairs | A1, A4ii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2019) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2019 | good | very high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | habitat | good | |
| 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 |
| Transportation and service corridors | likely in short term (<4 years) | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
| Pollution | likely in short term (<4 years) | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | No management planning has taken place | Very little or no conservation action taking place | low |
