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 IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Pink-eared Duck Malacorhynchus membranaceus	LC	resident (1983–2005)	13,189 individuals	A4i
Freckled Duck Stictonetta naevosa	LC	resident (1983–2005)	3,292 individuals	A4i
Black Swan Cygnus atratus	LC	resident (1983–2005)	30,482 individuals	A4i
Australasian Shoveler Spatula rhynchotis	LC	resident (1983–2005)	26,417 individuals	A4i
Grey Teal Anas gracilis	LC	resident (1983–2005)	38,849 individuals	A4i
Yellow-billed Spoonbill Platalea flavipes	LC	resident (1983–2005)	2,787 individuals	A4i
Straw-necked Ibis Threskiornis spinicollis	LC	resident (1983–2005)	41,600 individuals	A4i
Black-winged Stilt Himantopus himantopus	LC	resident (1983–2005)	22,579 individuals	A4i

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 key species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	moderate (70–90%)	moderate (70–90%)	unfavourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Climate change and severe weather	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Invasive and other problematic species and genes	happen­ing now	most of popul­ation/area (50–90%)	moderate deteri­oration (10–30% in 3 gener­ations)	high
Agricultural expansion and intensification	happen­ing now	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium
Pollution	happen­ing now	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium
Human intrusions and disturbance	happen­ing now	some of popul­ation/area (10–49%)	no deteri­oration (<1% over 3 gener­ations)	low
Biological resource use	happen­ing now	few individ­uals/small area (<10%)	no deteri­oration (<1% over 3 gener­ations)	low
Energy production and mining	happen­ing now	few individ­uals/small area (<10%)	no deteri­oration (<1% over 3 gener­ations)	low

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Most of site (50–90%) covered (including the most critical parts for important bird species)	A compre­hensive and appropriate manage­ment plan exists that aims to maintain or improve the popul­ations of qualify­ing bird species	Some limited conservation initiatives are in place	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
2004	Toogimbie	Indigenous Protected Area (VI)	<1
2007	Yanga	National Park (II)	15
2016	Yanga	National Park (II)	15

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	major (>10)	Arable land; Improved grassland & pasture
Savanna	major (>10)	Eucalypt open woodlands
Wetlands (inland)	major (>10)	Riverine floodplains

Land use	% of IBA
agriculture	major (>10)
nature conservation and research	major (>10)
rangeland/pastureland	major (>10)

Mostly private; also state government and indigenous land.
