The site was identified as important in 2007 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
Demoiselle Crane Anthropoides virgo	LC	breeding	2007	3 breeding pairs	A3
Little Bustard Tetrax tetrax	NT	breeding	2007	5-10 breeding pairs	A3
Steppe Eagle Aquila nipalensis	EN	passage	2007	8 individuals	A3
Eastern Imperial Eagle Aquila heliaca	VU	breeding	2007	15-20 breeding pairs	A1, A3
Pallid Harrier Circus macrourus	NT	breeding	2007	15-20 breeding pairs	A1, A3
Lesser Kestrel Falco naumanni	LC	breeding	2007	10-15 breeding pairs	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable
Wetlands (inland)	good (> 90%)	moderate (70-90%)	near favourable
Desert	good (> 90%)	good (> 90%)	favourable
Rocky areas (eg. inland cliffs, mountain peaks)	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Biological resource use	happening now	small area/few individuals (<10%)	slow but significant 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 - salty	91
Wetlands (inland)	Rivers & streams, Water-fringe vegetation	7
Rocky areas (eg. inland cliffs, mountain peaks)		2
Forest	Flood-plain, Wooded desert & semi-desert	minor (<10)

1. IUCN Habitat classification.
