IBA Justification

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 - 200-400 breeding pairs A1, A4i
Blue Crane Anthropoides paradiseus VU non-breeding - 1,000-2,500 individuals A1, A4i
Ludwig's Bustard Neotis ludwigii EN resident 1998 present A3
Karoo Bustard Heterotetrax vigorsii LC resident 1998 present A3
Blue Bustard Eupodotis caerulescens NT resident - present A1
Black Stork Ciconia nigra LC non-breeding - 10-20 individuals A4i
Lesser Kestrel Falco naumanni LC winter - 5,000-10,000 individuals A1, A4ii
Karoo Long-billed Lark Certhilauda subcoronata LC resident 1998 present A3
Karoo Lark Calendulauda albescens LC resident 1998 present A3
Namaqua Warbler Phragmacia substriata LC resident 1998 present A3
Layard's Warbler Curruca layardi LC resident 1998 present A3
Pale-winged Starling Onychognathus nabouroup LC resident 1998 present A3
Karoo Chat Emarginata schlegelii LC resident 1998 present A3
Sickle-winged Chat Emarginata sinuata LC resident 1998 present A3

Black-headed Canary Serinus alario LC resident 1998 present A3

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


IBA Conservation

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 very unfavourable high negligible
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
Forest poor (40-69%) poor (40-69%) very unfavourable
Shrubland moderate (70-90%) moderate (70-90%) unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Energy production and mining happening now 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
Climate change and severe weather likely in long term (beyond 4 years) whole area/population (>90%) 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
Natural system modifications happening now some of area/population (10-49%) slow but significant deterioration medium
Biological resource use happening now small area/few individuals (<10%) moderate to rapid deterioration low
Agricultural expansion and intensification happening now small area/few individuals (<10%) slow but significant deterioration low
Pollution likely in short term (within 4 years) small area/few individuals (<10%) slow but significant 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 Some limited conservation initiatives are in place negligible
