Data Zone
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 (2006) | 27 pairs | A3 |
| Little Bustard Tetrax tetrax | NT | breeding (2006) | 94 pairs | A1, A3 |
| Steppe Eagle Aquila nipalensis | EN | breeding (2006) | 255 pairs | A3 |
| Eastern Imperial Eagle Aquila heliaca | VU | breeding (2006) | 15 pairs | A1, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2010) is shown below.
