Data Zone
The site was identified as internationally important for bird conservation in 2023 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 |
|---|---|---|---|---|
| Red-crowned Amazon Amazona viridigenalis | EN | resident (2019) | 50 birds | A1, A2 |
| Yellow-headed Amazon Amazona oratrix | EN | resident (2017) | 400 birds | A1, A2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2023. The most recent assessment (2022) is shown below.

| Invasive and other problematic species and genes | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Agricultural expansion and intensification | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Human intrusions and disturbance | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Pollution | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Energy production and mining | likely in long term (>4 years) | few individuals/small area (<10%) | moderate decline (10–30% over 3 generations) | low |
