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:

Black-bellied Sandgrouse Pterocles orientalis	LC	resident (1996)	11–50 pairs	C6
Common Crane Grus grus	LC	winter (1996)	500–1,500 birds	A4i, B1i, B2, C2, C6
Little Bustard Tetrax tetrax	NT	resident (1996)	250–1,930 males	A1, B2, C1, C6
Great Bustard Otis tarda	EN	resident (1996)	80–100 pairs	A1, B2, C1, 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.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happe­ning now	few indivi­duals/small area (<10%)	rapid decline (>30% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	-	Arable land; Perennial crops, orchards and groves
Forest	-	Broadleaved evergreen woodland
Grassland	-	Steppes and dry calcareous grassland
Wetlands (inland)	-	Rivers and streams; Water fringe vegetation

Land use	% of IBA
