Data Zone
The site was identified as internationally important for bird conservation in 2021 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.
Populations meeting IBA criteria ('key species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Red-crowned Amazon Amazona viridigenalis | EN | resident (2019) | 18 individuals | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2022) is shown below.
