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
Red-tailed Tropicbird Phaethon rubricauda	LC	resident	1992-2007	389-450 breeding pairs	A4ii
Wedge-tailed Shearwater Ardenna pacifica	LC	resident	2001-2003	9,500-19,500 breeding pairs	A4ii
Lesser Frigatebird Fregata ariel	LC	resident	1992-2007	1,000-2,150 breeding pairs	A4ii
Red-footed Booby Sula sula	LC	resident	1992-2007	3,364-3,940 breeding pairs	A4ii
Black Noddy Anous minutus	LC	resident	1992-2007	10,000-22,000 breeding pairs	A4i

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 (2008) 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	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	whole area/population (>90%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
1982	Coringa-Herald	National Nature Reserve	100
2002	Coral Sea Reserves (Coringa-Herald and Lihou Reefs and Cays)	Ramsar Site, Wetland of International Importance	93
2012	Coral Sea	Commonwealth Marine Reserve	100
