The site was identified as important in 2015 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	2014	max 290 individuals	A1
Secretarybird Sagittarius serpentarius	EN	resident	2013-2015	< 50 individuals	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2015) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2015. The most recent assessment (2014) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Aquatic & Marine	good (> 90%)	moderate (70-90%)	near favourable
Grassland	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Transportation and service corridors	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Other	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Natural system modifications	happening now	small area/few individuals (<10%)	no or imperceptible 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 planning has taken place	Very little or no conservation action taking place	negligible
