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 |
| Southern Bald Ibis Geronticus calvus | NT | resident (-) | present | A1 |
| Blue Swallow Hirundo atrocaerulea | EN | breeding (1998) | present | A1 |
| Bush Blackcap Sylvia nigricapillus | VU | 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 (2013) is shown below.

| Human intrusions and disturbance | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Residential and commercial development | happening now | few individuals/small area (<10%) | moderate decline (10–30% over 3 generations) | low |

|---|---|---|---|
| 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 |
