The site was identified as internationally important for bird conservation in 2002 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
Black-bellied Sandgrouse Pterocles orientalis	LC	resident (2000)	40–60 pairs	C6
Little Bustard Tetrax tetrax	NT	resident (2000)	abundant	A1, C1
Collared Pratincole Glareola pratincola	LC	breeding (2000)	40–150 pairs	A4i, B1i, B2, C2, C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2005) is shown below.

Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happe­ning now	few indivi­duals/small area (<10%)	rapid decline (>30% over 3 gener­ations)	low
