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:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Malleefowl Leipoa ocellata	VU	resident (1989–2008)	500 birds	A1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Shrubland	very poor (<40%)	very poor (<40%)	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Energy production and mining	likely in short term (<4 years)	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	high
Natural system modifications	likely in long term (>4 years)	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	No management plan exists, but the management planning process has begun	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	low

Year	Protected Area	Designation (management category)	% coverage of IBA
-	Southern Mallee	Protected Area (-)	9
1981	Willandra Lakes Region	World Heritage Site (natural or mixed) (UA)	6
1983	Mallee Cliffs	National Park (Ia)	7
2010	Kemendok	National Park (II)	<1
2010	Euston	Regional Park (V)	<1
2011	Mungo	State Conservation Area (II)	<1
2012	Mungo	National Park (II)	2

Habitat	% of IBA	Habitat detail
Shrubland	95	Chenopod shrubs, samphire shrubs and forblands; Mallee shrublands & woodlands
Artificial/Terrestrial	5	Arable land

Land use	% of IBA
rangeland/pastureland	72
nature conservation and research	28

Mostly leasehold but also NSW NPWS.
