The site was identified as internationally important for bird conservation in 2011 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
Common Crane Grus grus	LC	winter (2007)	min 11,176 birds	A4i, B1i, C2
Black Stork Ciconia nigra	LC	non-breeding (1996)	41–100 birds	B1i, C2, C6
Black Stork Ciconia nigra	LC	breeding (2009)	7 pairs	B1i, C2, C6
Great Cormorant Phalacrocorax carbo	LC	resident (2003)	110–222 pairs	B1i, C3
Cinereous Vulture Aegypius monachus	NT	resident (2003)	1–10 pairs	A1, C1, C2
Spanish Imperial Eagle Aquila adalberti	VU	resident (2009)	4–5 pairs	A1, B2, C1, C2, C6
Red Kite Milvus milvus	LC	resident (2003)	13–130 pairs	A1, B2, C1, C2
European Roller Coracias garrulus	LC	breeding (2003)	11–110 pairs	A1, B2, C1, C2
Dartford Warbler Curruca undata	NT	resident (2003)	121–1,210 pairs	A1, C1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2008) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Common Crane Grus grus	10,000 / 5,244 (birds)	100	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Climate change and severe weather	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
