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
Cape Spurfowl Pternistis capensis	LC	resident (1998)	present	A3
Cape Shoveler Spatula smithii	LC	non-breeding (-)	604–3,004 birds	A4i
Yellow-billed Duck Anas undulata	LC	non-breeding (-)	319–4,626 birds	A4i
Great Crested Grebe Podiceps cristatus	LC	non-breeding (-)	95–180 birds	A4i
Greater Flamingo Phoenicopterus roseus	LC	non-breeding (-)	1,473 birds	A4i

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.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Shrubland	good (>90%)	moderate (70–90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Human intrusions and disturbance	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Transportation and service corridors	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Energy production and mining	likely in short term (<4 years)	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Natural system modifications	likely in short term (<4 years)	few indivi­duals/small area (<10%)	slow decline (1–10% 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	The conservation measures needed for the site are being compre­hensively and effectively implemented	high
