The site was identified as important 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 List1	Season	Year(s)	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 breeding pairs	A1, A4i
Southern Bald Ibis Geronticus calvus	NT	non-breeding	-	200-300 individuals	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

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1998) may differ.

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
Grassland	very poor (< 40%)	moderate (70-90%)	very unfavourable
Wetlands (inland)	poor (40-69%)	poor (40-69%)	very unfavourable
Savanna	moderate (70-90%)	good (> 90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Energy production and mining	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	past (and unlikely to return) and no longer limiting	whole area/population (>90%)	moderate to rapid deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management plan exists but the management planning process has begun	Very little or no conservation action taking place	negligible
