Data Zone
The site was identified as internationally important for bird conservation in 2007 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 (-) | present | A1 |
| Crowned Solitary Eagle Buteogallus coronatus | EN | resident (1998–2007) | present | A1 |
| Bearded Tachuri Polystictus pectoralis | NT | resident (-) | present | A1 |
| Strange-tailed Tyrant Alectrurus risora | VU | resident (1998–2007) | present | A1 |
| Dark-throated Seedeater Sporophila ruficollis | NT | resident (-) | present | A1 |
| Rufous-rumped Seedeater Sporophila hypochroma | NT | resident (-) | present | A1 |
| Marsh Seedeater Sporophila palustris | EN | passage (1998–2007) | present | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2011) is shown below.
| IBA conservation assessment | |||
