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
Magpie Goose Anseranas semipalmata	LC	non-breeding (1986–1995)	268–602,000 birds	A4i
Pink-eared Duck Malacorhynchus membranaceus	LC	resident (1986–1995)	5,600–34,000 birds	A4i
Freckled Duck Stictonetta naevosa	LC	non-breeding (1986–1995)	898 birds	A4i
Hardhead Aythya australis	LC	resident (1986–1995)	1,800–104,519 birds	A4i
Pacific Black Duck Anas superciliosa	LC	resident (1986–1995)	2,249–7,000 birds	A4i
Grey Teal Anas gracilis	LC	resident (1986–1995)	2,200–46,000 birds	A4i
Brolga Grus rubicunda	LC	resident (1986–1995)	47–4,585 birds	A4i
Australian Bustard Ardeotis australis	LC	resident (1998–2008)	common	A1
Little Black Cormorant Phalacrocorax sulcirostris	LC	resident (1986–1995)	20–60,000 birds	A4i
Oriental Plover Charadrius veredus	LC	non-breeding (1986–1995)	901–25,707 birds	A4i
Sharp-tailed Sandpiper Calidris acuminata	VU	non-breeding (1986–1995)	540–12,500 birds	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 (2020) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	moderate (70–90%)	good (>90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	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
Whole area (>90%) covered by appropriate conservation designation	Unknown	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
2002	Paruku	Indigenous Protected Area (II)	74

Habitat	% of IBA	Habitat detail
Shrubland	major (>10)	Chenopod shrubs, samphire shrubs and forblands
Wetlands (inland)	major (>10)	Ephemeral; Freshwater lakes & pools
Grassland	minor (<10)	Hummock grasslands
Savanna	minor (<10)	Acacia open woodlands; Eucalypt open woodlands

Land use	% of IBA
hunting	major (>10)
rangeland/pastureland	major (>10)
other	major (>10)

Paruku/Lake Gregory and Billiluna properties are managed by the Mulan community and owned by the Walmajarri, Jaru and Kukatja peoples.
