It is vast. It is in arid country, 100 kilometres north of Broken Hill. An incredible place, it encompasses a hilly range, the same one that Broken Hill is a part of, ephemeral Eucalypt dominated creeks and grass or copper bush dominated plains. David Keith, in his excellent book ‘Ocean Shores to Desert Dunes’ (More information on the book) describes two ecological communities that are present here. Gibber Chenopod Shrublands in the hills and Aeolian Chenopod Shrublands on the plains.
The plains are highly variable, sometimes Mitchell Grass dominated (pictured above), sometimes Maireana (Bluebush) and other times a mix. But, they are surprisingly diverse and it appears a healthy ecosytem supporting an array of wildlife. The Marieana, a Chenopod, has a fruit with wings ideally adapted for wind dispersal. I think the species shown is Maireana sedifolia.
The hills are harsher. Feral goats compete with the Euro kangaroo and other wildlife so that it appears in places over grazed and hostile.
