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'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
A4iv Species group - soaring birds/cranes	n/a	passage	2001-2003	92,000-115,000 individuals	A4iv

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2007).
