Data Zone
The site was identified as internationally important for bird conservation 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 List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Coscoroba Swan Coscoroba coscoroba | LC | resident (2016–2020) | 321–387 birds | A4, B3a |
| Black-necked Swan Cygnus melancoryphus | LC | resident (2008) | 1,000-2,499 birds | A4i |
| Chilean Flamingo Phoenicopterus chilensis | NT | winter (2008) | 200 birds | A1 |
| Chilean Flamingo Phoenicopterus chilensis | NT | non-breeding (2016–2020) | 13–269 birds | B1a |
| Peruvian Pelican Pelecanus thagus | NT | non-breeding (2016–2020) | 3–31 birds | B1a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2020) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2020 | very poor | very high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | good | |

|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Intertidal | - | poor (40–69%) | very poor |
| Marine Coastal/Supratidal | - | moderate (70–90%) | poor |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | happening now | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Geological events | likely in short term (<4 years) | some of population/area (10–49%) | rapid decline (>30% over 3 generations) | high |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Natural system modifications | likely in short term (<4 years) | 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 | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
