The site was identified as important in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

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
Desert	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	very rapid to severe deterioration	high
Agricultural expansion and intensification	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%)	moderate to rapid deterioration	high
Transportation and service corridors	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Biological resource use	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	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 plan exists but the management planning process has begun	Very little or no conservation action taking place	negligible
