An area of 593 sqkm located at the northern of the wetland system and that is specifically associated with a number of water bodies has been identified as an important bird area by Birdlife International because it supports “more than 1% of the world populations of 12 species of waterbird and shorebird” as well as “populations of the vulnerable Australian painted snipe, the near threatened blue-billed duck, the restricted-range Eyrean grasswren and five species restricted to the arid biome.”
