Data Zone
The site was identified as internationally important for bird conservation in 2007 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 | breeding (2004) | 1–10 pairs | A1, B2 |
| Ferruginous Duck Aythya nyroca | NT | breeding (2004) | 15–25 pairs | A1, B2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2006) is shown below.

| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | happening now | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | high |
| Agricultural expansion and intensification | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Little/none of area covered (<10%) | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
| Habitat | % of IBA | Habitat detail |
|---|---|---|
| Desert | 16 | Semidesert |
| Wetlands (inland) | major (>10) | Standing brackish and salt water |
