The site was identified as internationally important for bird conservation in 2013 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
Sand Partridge Ammoperdix heyi	LC	resident (1993)	present	A3, B3
Lichtenstein's Sandgrouse Pterocles lichtensteinii	LC	resident (1993)	present	A3
Nubian Nightjar Caprimulgus nubicus	LC	resident (1993)	5 pairs	B2
Malachite Kingfisher Corythornis cristatus	LC	resident (1993)	present	B2
Pale Rock Martin Ptyonoprogne obsoleta	LC	resident (1993)	present	A3
Arabian Warbler Curruca leucomelaena	LC	resident (1993)	present	A3, B3
Blackstart Oenanthe melanura	LC	resident (1993)	present	A3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2013. The most recent assessment (2013) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	likely in long term (>4 years)	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Not assessed	very low

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	major (>10)
Introduced vegetation	minor (<10)
Shrubland	minor (<10)
Wetlands (inland)	minor (<10)

Land use	% of IBA
agriculture	major (>10)
rangeland/pastureland	minor (<10)
