Data Zone
The site was identified as internationally important for bird conservation in 1998 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 |
|---|---|---|---|---|
| Blue Crane Anthropoides paradiseus | VU | resident (-) | present | A1 |
| Blue Bustard Eupodotis caerulescens | NT | resident (-) | present | A1 |
| Southern Bald Ibis Geronticus calvus | NT | resident (-) | 80–100 pairs | A1, A4i |
| Southern Bald Ibis Geronticus calvus | NT | non-breeding (-) | 200–300 birds | A1, A4i |
| Black Harrier Circus maurus | EN | resident (-) | present | A1 |
| Lesser Kestrel Falco naumanni | LC | winter (-) | present | A1 |
| Buff-streaked Chat Campicoloides bifasciatus | LC | resident (1998) | present | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2014) is shown below.
| IBA conservation assessment | |||

| 2014 | very poor | high | very low |

| Agricultural expansion and intensification | happening now | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | high |
| Invasive and other problematic species and genes | happening now | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | high |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Residential and commercial development | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |

| Transportation and service corridors | 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 |
| Pollution | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
