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 (2015) | min 30 males | B1a |
| Mottled Piculet Picumnus nebulosus | NT | resident (2017) | min 30 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.
