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 | 40-45 breeding pairs | A3 |
Steppe Eagle Aquila nipalensis | EN | breeding | 2007 | 40-50 breeding pairs | A3 |
