The site was identified as internationally important for bird conservation in 2016 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 List	Season (year/s of estimate)	Size	IBA criteria
Blue-billed Duck Oxyura australis	LC	non-breeding (2007–2010)	950 birds	A1, A4i
Pink-eared Duck Malacorhynchus membranaceus	LC	non-breeding (1989–2010)	22,000 birds	A4i
Freckled Duck Stictonetta naevosa	LC	resident (1989–2010)	1,143–3,500 birds	A4i
Hardhead Aythya australis	LC	resident (1989–2010)	38,000 birds	A4i
Grey Teal Anas gracilis	LC	resident (1989–2010)	37,000 birds	A4i
Banded Stilt Cladorhynchus leucocephalus	LC	non-breeding (1989–2010)	4,000 birds	A4i
Red-capped Plover Charadrius ruficapillus	LC	resident (2007–2010)	1,225–1,970 birds	A4i
Inland Dotterel Peltohyas australis	LC	non-breeding (1989–2010)	common birds	A3
Bourke's Parrot Neopsephotus bourkii	LC	resident (1989–2010)	abundant birds	A3
A4iii Species group - waterbirds	n/a	- (1989–2010)	45,000–150,000 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2016) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	likely in long term (>4 years)	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	medium
Energy production and mining	likely in long term (>4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium
Climate change and severe weather	likely in long term (>4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium
Residential and commercial development	likely in long term (>4 years)	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed

Habitat	% of IBA	Habitat detail
Wetlands (inland)	90	Ephemeral
Desert	10	Semi-desert (includes gibber plains)

Land use	% of IBA

Most wetlands lie on 'Roxby Downs, Purple Downs and Andamooka Pastoral Leases' (primary lLessee BHP Billiton, Olympic Dam, recently subleased to the Kokatha People -the local Native Title holders).
