It occupies semi-arid mallee scrub on the fringes of the relatively fertile areas of southern Australia, where it is now reduced to three separate populations: the Murray-Murrumbidgee basin, west of Spencer Gulf along the fringes of the Simpson Desert, and the semi-arid fringe of Western Australia's fertile south-west corner.
The site was identified as an IBA because it supports an isolated population of the vulnerable Malleefowl as well as populations of Diamond Firetails and Painted Honeyeaters.
Conditions were set in response to the presence of two threatened species within the project area: the Slender-billed Thornbill and the Malleefowl.
