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
Blue-billed Duck Oxyura australis	LC	resident (-)	1,560 birds	A1, A4i
Musk Duck Biziura lobata	LC	resident (-)	1,289 birds	A4i
Pink-eared Duck Malacorhynchus membranaceus	LC	resident (-)	18,000 birds	A4i
Freckled Duck Stictonetta naevosa	LC	resident (-)	730 birds	A4i
Black Swan Cygnus atratus	LC	resident (-)	14,000 birds	A4i
Australian Shelduck Tadorna tadornoides	LC	resident (-)	14,705 birds	A4i
Australasian Shoveler Spatula rhynchotis	LC	resident (-)	7,060 birds	A4i
Chestnut Teal Anas castanea	LC	resident (-)	5,580 birds	A4i
Hoary-headed Grebe Poliocephalus poliocephalus	LC	resident (-)	6,597 birds	A4i
Straw-necked Ibis Threskiornis spinicollis	LC	resident (-)	90,000 birds	A4i
Banded Stilt Cladorhynchus leucocephalus	LC	non-breeding (-)	112,000 birds	A4i
Black-winged Stilt Himantopus himantopus	LC	resident (-)	12,000 birds	A4i
Sharp-tailed Sandpiper Calidris acuminata	VU	non-breeding (-)	10,000 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 (2018) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	good (>90%)	very poor (<40%)	very poor

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%)	moderate decline (10–30% over 3 gener­ations)	very high
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Pollution	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
Some of area covered (10–49%)	A management plan exists, but it is out of date or not compre­hensive	Very little or no conservation action taking place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
1981	Lake Bookar W.R	Natural Features Reserve (VI)	1
1981	Lake Terangpom W.R	Nature Conservation Reserve (Ia)	1

1986	Milangil Lake W.R	Nature Conservation Reserve (Ia)	1
1989	Lake Beeac W.R	Nature Conservation Reserve (Ia)	2

Habitat	% of IBA	Habitat detail
Wetlands (inland)	major (>10)	Ephemeral; Freshwater lakes & pools; Saline lakes; Salt marshes

Land use	% of IBA
nature conservation and research	major (>10)

Most managed by Parks Victoria. Lakes Beeac, Bookaar, Cundare, Milangil, Murdeduke and Terangpom are State Wildlife Reserves. Lakes Colongulac, Corangamite and Gnarpurt are Lake Reserves. Lake Thurrumbong is a State Game Reserve. Cundare Pool/Lake Martin and Lough Calvert are public land managed by Southern Rural Water.
