The site was identified as internationally important for bird conservation 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:

Bush Thick-knee Burhinus grallarius	LC	resident (1998–2008)	uncommon	A1
Chestnut-backed Buttonquail Turnix castanotus	LC	resident (1986–1987)	uncommon	A1, A2, A3
Hooded Parrot Psephotellus dissimilis	LC	resident (1986–2008)	uncommon	A2, A3

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 of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Invasive and other problematic species and genes	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)

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.
