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
Barbary Partridge Alectoris barbara	LC	resident (1996)	6 pairs	B2
African Houbara Chlamydotis undulata	VU	resident (2006)	11–17 birds	A1, B2, C1
White-faced Storm-petrel Pelagodroma marina	LC	breeding (2000–2001)	35–55 pairs	C6
European Storm-petrel Hydrobates pelagicus	LC	breeding (2000–2001)	280–540 pairs	B1ii, C2, C6
Band-rumped Storm-petrel Hydrobates castro	LC	breeding (2000–2001)	115–185 pairs	B1ii, B2, C2, C6
Cory's Shearwater Calonectris borealis	LC	non-breeding (2006)	min 10,000 birds	A4ii, B1ii, C2, C6
Cory's Shearwater Calonectris borealis	LC	breeding (2000–2001)	10,492–13,500 pairs	A4ii, B1ii, B2, C2, C6
Audubon's Shearwater Puffinus lherminieri	LC	breeding (2000–2001)	30–60 pairs	B1ii, B2, C2, C6
Bulwer's Petrel Bulweria bulwerii	LC	breeding (2000–2001)	210–390 pairs	B1ii, B2, C2, C6
Osprey Pandion haliaetus	LC	resident (2001)	4–5 pairs	C6
Egyptian Vulture Neophron percnopterus	EN	resident (2008)	2 pairs	A1, C1, C6
Eleonora's Falcon Falco eleonorae	LC	breeding (2008)	276–307 pairs	A4ii, B1iii, B2, C2, C6
Berthelot's Pipit Anthus berthelotii	LC	resident (2009)	present	B3
A4iii Species group - seabirds	n/a	breeding (1987)	9,230–12,000 pairs	A4iii, C4

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
Bulwer's Petrel Bulweria bulwerii	210 / 210 (birds)	100	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Pollution	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
1987	Archipiélago de Chinijo	Parque Natural (II)	3
1987	Los Islotes	Reserva Natural Integral (Ib)	<1
1995	Reserva Marina de la Isla Graciosa y de los Islotes del Norte de Lanzarote	Reservas Marinas (VI)	49
