Geography

edit

The bioregion contains Lake Galilee, Lake Dunn and Lake Buchanan. The climate is semi-arid with highly variable rainfall. Much of the area is used for cattle grazing and is part of the Great Artesian Basin, lying within both the Galilee and Eromanga Basins. The Brigalow Belt North and Brigalow Belt South are to the east of the bioregion, and the Einasleigh Uplands are located to the north.[2]

Waterways

edit

The main rivers in the bioregion are Belyando, Cape, Campaspe, Barcoo and Alice River and Aramac and Torrens Creeks.[1] Wetlands at shallow salt lakes Lake Galilee and Lake Buchanan are listed on the Directory of Important Wetlands in Australia.

Subregions

edit

The Desert Uplands bioregion has four subregions:[3]

  • Prairie-Torrens Creeks Alluvials (DEU01) – 1,580,384 hectares (3,905,210 acres)
  • Alice Tableland (DEU02) – 2,866,760 hectares (7,083,900 acres)
  • Cape-Campaspe Plains (DEU03) – 1,007,026 hectares (2,488,420 acres)
  • Jericho (DEU04) – 1,486,926 hectares (3,674,270 acres)

Flora

Spinifex grass is common. More than 80 weeds have been identified in the bioregion.[4]

In 2003, it was estimated that 13 million trees per year were being destroyed in the Desert Uplands.[5] This placed the percentage of land cleared at 6.8%, the third highest for any Queensland bioregion.

Settlements
