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
Eurasian Eagle-owl Bubo bubo	LC	resident (2001)	9 pairs	C6
Egyptian Vulture Neophron percnopterus	EN	non-breeding (1995)	min 90 birds	A1, B1iii, B2, C1, C2, C6
Egyptian Vulture Neophron percnopterus	EN	breeding (2008)	32–36 pairs	A1, B1iii, B2, C1, C2, C6
Griffon Vulture Gyps fulvus	LC	resident (2008)	735–896 pairs	A4ii, B1iii, C2, C6
Bonelli's Eagle Aquila fasciata	LC	non-breeding (2009)	max 1 birds	C6
Bonelli's Eagle Aquila fasciata	LC	resident (2009)	present	C6
Peregrine Falcon Falco peregrinus	LC	resident (2008)	14–17 pairs	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2007) is shown below.
