The site was identified as important in 2011 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
Little Bustard Tetrax tetrax	NT	resident	2005	min 250 individuals	A1, C1
Little Bustard Tetrax tetrax	NT	winter	2006	min 50 individuals	A1, C1
Black Stork Ciconia nigra	LC	breeding	2003	min 6 breeding pairs	B1i, C2
Egyptian Vulture Neophron percnopterus	EN	breeding	2008	min 12 breeding pairs	A1, C1, C2
Griffon Vulture Gyps fulvus	LC	resident	2008	min 187 breeding pairs	C2, C6
Cinereous Vulture Aegypius monachus	NT	resident	2008	18-20 breeding pairs	A1, B1iii, B2, C1, C2
Spanish Imperial Eagle Aquila adalberti	VU	resident	2010	2 breeding pairs	A1, B2, C1, C2
Booted Eagle Hieraaetus pennatus	LC	breeding	2009	min 25 breeding pairs	B2, C2
Red Kite Milvus milvus	LC	breeding	2005	min 11 breeding pairs	A1, C1
Red Kite Milvus milvus	LC	winter	2005	min 200 individuals	A1, C1

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2011).
