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
Bridled Tern Onychoprion anaethetus	LC	resident	1987-1998	3,000-10,000 breeding pairs	A4i
Lesser Crested Tern Thalasseus bengalensis	LC	resident	1985-1986	850-1,000 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 (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	medium
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	medium

Year	Protected Area	Designation	% overlap with IBA
1981	Great Barrier Reef	World Heritage Site (natural or mixed)	100
1998	Barnard Island Group	National Park	100
2004	Great Barrier Reef	Marine Park	96
2004	Great Barrier Reef Coast	Marine Park	88

Habitat1	Habitat detail	% of IBA
Forest	Mangroves, Rainforest & vine thickets	major (>10)
Marine Coastal/Supratidal		minor (<10)
Marine Intertidal		minor (<10)
