Data Zone
The site was identified as important in 2020 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 |
|---|---|---|---|---|---|
| Pink-footed Shearwater Ardenna creatopus | VU | breeding | 2016-2020 | 300-2,000 individuals | A1, A4 |
| Peruvian Pelican Pelecanus thagus | NT | resident | 2016-2020 | 25-1,500 individuals | B1a |
| Red-legged Cormorant Poikilocarbo gaimardi | NT | resident | 2016-2020 | 20-400 individuals | B1a |

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2020) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2014) is shown below.
| IBA conservation assessment | |||

| Year of assessment | State | Pressure | Response |
| 2014 | favourable | high | medium |
| Whole site assessed? | State assessed by | Accuracy of information | |

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Residential and commercial development | happening now | majority/most of area/population (50-90%) | moderate to rapid deterioration | high |

| Protected areas | Management plan | Other action | Result |
| Most of site (50-90%) covered (including the most critical parts for important bird species) | A management plan exists but it is out of date or not comprehensive | Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity | medium |
