Data Zone
The site was identified as internationally important for bird conservation in 2001 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 |
|---|---|---|---|---|
| White-headed Duck Oxyura leucocephala | EN | resident (-) | 20–50 birds | A1 |
| Marbled Duck Marmaronetta angustirostris | NT | winter (-) | 50–100 birds | A1, A4i |
| Ferruginous Duck Aythya nyroca | NT | passage (-) | 200–300 birds | A1 |
| A4iii Species group - waterbirds | n/a | non-breeding (-) | 20,000 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2009) is shown below.

| Climate change and severe weather | likely in long term (>4 years) | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | medium |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Biological resource use | happening now | few individuals/small area (<10%) | slow decline (1–10% over 3 generations) | low |
