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
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low
Invasive and other problematic species and genes	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
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
1990	Eighty-mile Beach	Ramsar Site, Wetland of International Importance	42
2015	Nyangumarta Warrarn	Indigenous Protected Area	33

Habitat1	Habitat detail	% of IBA
Grassland	Tussock grasslands	major (>10)
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)

1. IUCN Habitat classification.

Land use	% of IBA
rangeland/pastureland	major (>10)
