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:

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 (2016) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	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
1985	The Coorong, and Lakes Alexandrina and Albert Wetland	Ramsar Site, Wetland of International Importance	96
2000	Unnamed (No.HA1201)	Heritage Agreement	<1
2009	Encounter	Marine Park	8
2011	Coorong	National Park	100
