The site was identified as important in 2009 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 List1	Season	Year(s)	Size	IBA criteria
European Shag Gulosus aristotelis	LC	breeding	2004-2009	1,081-1,734 breeding pairs	B1i, B3
Great Cormorant Phalacrocorax carbo	LC	breeding	2004-2009	346-501 breeding pairs	B1i, C3
Great Black-backed Gull Larus marinus	LC	breeding	2004-2007	145-169 breeding pairs	B3
Razorbill Alca torda	LC	breeding	2004-2009	5,685-6,399 individuals	B1ii, B3, C3
Common Murre Uria aalge	LC	breeding	2004-2009	58,207-67,314 individuals	B1ii, C3
A4iii Species group - seabirds	n/a	breeding	2004-2007	50,000-99,999	A4iii, C4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2013) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	likely in short term (within 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	No management planning has taken place	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
1995	Lambay Island SPA	Special Protection Area (Birds Directive)	98
1995	Lambay Island SAC	Site of Community Importance (Habitats Directive)	66
2011	Rockabill to Dalkey Island SAC	Site of Community Importance (Habitats Directive)	35

Habitat1	Habitat detail	% of IBA
Marine Neritic		55
Marine Intertidal		20
Grassland	Mesophile grasslands, Machair	10
Artificial/Terrestrial	Ruderal land	5
Forest	Mixed woodland	5
Shrubland	Scrub	5
Marine Coastal/Supratidal		minor (<10)

1. IUCN Habitat classification.
