Data Zone
The site was identified as internationally important for bird conservation in 2022 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 (2012–2021) | min 30 birds | B1a |
| Yellow-legged Tinamou Crypturellus noctivagus | NT | resident (2014) | min 30 birds | B1a |
| White-browed Guan Penelope jacucaca | VU | resident (2014–2022) | min 30 birds | A1 |
| Lear's Macaw Anodorhynchus leari | EN | resident (2019) | min 1,000 birds | A1, A4 |
| Blue-winged Macaw Primolius maracana | NT | resident (2012–2019) | 30 birds | B1a |
| Pectoral Antwren Herpsilochmus pectoralis | VU | resident (2013) | min 30 birds | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. The most recent assessment (2022) is shown below.
