The site was identified as important in 2006 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
Little Bustard Tetrax tetrax	NT	breeding	2006	5-10 breeding pairs	A3
Black-winged Pratincole Glareola nordmanni	NT	breeding	2006	29 individuals	A1, A3
Eastern Imperial Eagle Aquila heliaca	VU	breeding	2006	5-7 breeding pairs	A1, A3
Lesser Kestrel Falco naumanni	LC	breeding	2006	15-20 breeding pairs	A1
Black Lark Melanocorypha yeltoniensis	LC	breeding	2006	500 individuals	A3
Red-headed Bunting Emberiza bruniceps	LC	breeding	2006	40-50 breeding pairs	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2006) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2006) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	good (> 90%)	moderate (70-90%)	near favourable
Wetlands (inland)	good (> 90%)	moderate (70-90%)	near favourable
Shrubland	good (> 90%)	good (> 90%)	favourable
Desert	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Natural system modifications	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
Not assessed	Not assessed	Not assessed	not assessed

Habitat1	Habitat detail	% of IBA
Desert	Desert & semi-desert - clay, Desert & semi-desert - sandy	85
