Key Biodiversity Areas: 2
Ozcranes KBAs Part 2 covers six KBAs in Western Australia and Northern Territory which are significant habitat for Brolgas. For background to the KBA program, and details of Queensland KBAs important for Sarus Cranes and Brolgas, see KBAs 1». A larger map showing 2008 aerial count results for Brolgas across Australia is in Brolga FAQ1».
Australian KBAs and cranes
Eight KBAs in Australia have been chosen based on their critical habitat for Brolgas and Sarus Cranes, as well as significant populations of other waterbirds or range-restricted species.

Brolga KBAs: WA & NT
Lake Gregory is significant freshwater to saline wetland in arid Western Australia, with important breeding populations of waterfowl and major influxes of migratory waterbirds. A paper can be downloaded from University of Queensland: Halse, SA, GB Pearson, and WR Kay. ‘Arid zone networks in time and space: waterbird use of Lake Gregory in north-western Australia.’ International Journal of Ecology and Environmental Sciences 24 (1998): 207-222.

Mandora Marsh and Anna Plains
This KBA is a seasonally flooded wetland in Western Australia supporting significant populations of a number of waterbirds, including over 3,500 Brolgas. Halse et al 2005, ‘Mandora Marsh, north-western Australia, an arid-zone wetland maintaining continental populations of waterbirds.’ Emu 105, no. 2 (2005): 115-125.

These Northern Territory floodplains on Boucalt Bay support up to 3,000 Brolgas and other waterbirds. For more search at BirdLife International Datazone as above.
Blue Mud Bay
This large bay on the western Gulf of Carpentaria, Northern Territory, supports some 3,000 Brolgas and significant populations of Magpie Geese and Whistle Ducks. For more search at BirdLife International Datazone as above.
This large inland floodplain in the Northern Territory Top End, and nearby coastal saline flats, support up to 7,000 resident Brolgas as well as significant populations of other waterbirds. For more search at BirdLife International Datazone as above.
Alligator Rivers Floodplains
This extensive floodplain complex, plus smaller wetlands and saline swamps, have been estimated to support over 1 million waterbirds including up to 24,000 Brolgas. Morton et al 1993, ‘Distribution and abundance of Brolgas and Black-necked Storks in the Alligator Rivers region, Northern Territory.’ Emu 93, no. 2 (1993): 88-92. The abstract can be viewed at Emu. Much of the area is protected in the renowned Kakadu National Park. The Plan for Kakadu National Park including the significant wetlands can be downloaded from Environment Australia.
