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
Natural system modifications	happening now	whole area/population (>90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Agricultural expansion and intensification	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

Habitat1	Habitat detail	% of IBA
Grassland	Tussock grasslands	major (>10)

1. IUCN Habitat classification.

Land use	% of IBA
other	major (>10)

Predominantly Aboriginal freehold land (Wagiman Aboriginal Land Trust and Barnjarn Aboriginal Corporation). West of the Stuart Highway there are some parcels of privately owned freehold land and a small area of Nitmiluk National Park.
