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 |
|---|---|---|---|---|
| Southern Bald Ibis Geronticus calvus | NT | resident (-) | present | A1 |
| Rudd's Lark Heteromirafra ruddi | EN | resident (-) | present | A1 |
| Botha's Lark Spizocorys fringillaris | EN | resident (-) | present | A1 |
| Yellow-breasted Pipit Hemimacronyx chloris | VU | resident (-) | 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 | |||

| Year of assessment | State | Pressure | Response |
| 2014 | poor | high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | medium | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Coastal/Supratidal | moderate (70–90%) | moderate (70–90%) | poor |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Energy production and mining | likely in short term (<4 years) | some of population/area (10–49%) | moderate decline (10–30% 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%) | moderate decline (10–30% over 3 generations) | low |
| Invasive and other problematic species and genes | happening now | few individuals/small area (<10%) | slow decline (1–10% over 3 generations) | low |
| Transportation and service corridors | happening now | few individuals/small area (<10%) | slow decline (1–10% over 3 generations) | low |
| Pollution | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Residential and commercial development | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Agricultural expansion and intensification | likely in short term (<4 years) | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | 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 | high |
| Habitat | % of IBA | Habitat detail |
|---|---|---|
| Artificial/Terrestrial | major (>10) | Arable land |
| Grassland | major (>10) | Grassland - highveld |
| Artificial/Aquatic & Marine | minor (<10) |
