Data Zone
The site was identified as internationally important for bird conservation in 2024 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 |
|---|---|---|---|---|
| Greater Rhea Rhea americana | NT | resident (2016–2024) | 30–294 birds | B1a |
| Dot-winged Crake Laterallus spilopterus | VU | resident (2018–2024) | 30–87 birds | A1 |
| Buff-breasted Sandpiper Calidris subruficollis | VU | non-breeding (2015) | min 250 birds | B1a |
| Straight-billed Reedhaunter Limnoctites rectirostris | NT | resident (2015) | min 90 birds | B1a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2024. The most recent assessment (2024) is shown below.
