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
Common Crane Grus grus	LC	winter (2002)	800–1,000 unknown	A4i, B1i, B2, C2, C6
Little Bustard Tetrax tetrax	NT	resident (2002)	120–150 birds	A1, B2, C1, C6
Great Bustard Otis tarda	EN	resident (2002)	50–60 birds	A1, C1, C6
Eurasian Thick-knee Burhinus oedicnemus	LC	breeding (1996)	20–30 pairs	B2, C6
Montagu's Harrier Circus pygargus	LC	breeding (2002)	15–20 pairs	B3, 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
