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
Black Swan Cygnus atratus	LC	resident	1997-2006	2-13,040 individuals	A4i
Chestnut Teal Anas castanea	LC	resident	1999-2001	4-5,000 individuals	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
Marine Coastal/Supratidal	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Pollution	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	past (and unlikely to return) and no longer limiting	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
Whole area of site (>90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium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	% overlap with IBA
2009	Jervis Bay	National Park	100

Habitat1	Habitat detail	% of IBA
Marine Coastal/Supratidal		90
Marine Intertidal		minor (<10)

1. IUCN Habitat classification.

Land use	% of IBA
nature conservation and research	major (>10)
fisheries/aquaculture	minor (<10)
tourism/recreation	minor (<10)
