Current view: Data table and detailed info

IBA Justification

The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Demoiselle Crane Anthropoides virgo	LC	breeding (2007)	1 pairs	A3
Little Bustard Tetrax tetrax	NT	breeding (2007)	20–50 pairs	A1, A3
Asian Houbara Chlamydotis macqueenii	VU	breeding (2007)	1–10 pairs	A1
Steppe Eagle Aquila nipalensis	EN	breeding (2007)	15 birds	A3
Eastern Imperial Eagle Aquila heliaca	VU	breeding (2007)	20–30 pairs	A1, A3

IBA Conservation

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.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2007	moderate	high	not assessed
Whole site assessed?	State assessed by	Accuracy of information
