Volume 2, Part 2, page 243 Simpson-Strzelecki Dunefields 9. Simpson-Strzelecki Dunefields Bioregion 9.1 OVERVIEW OF THE NT PORTION OF THE SIMPSON-STRZELECKI DUNEFIELDS BIOREGION The Simpson-Strzelecki Dunefields bioregion comprises an area of 277,800km2, 38% (105,900km2) of which is located in the Northern Territory, covering the entire south eastern corner of the study area. The remainder of this bioregion extends across New South Wales, Queensland and South Australia. The NT portion of the bioregion is relatively uniform. It presents as an immense plain with parallel siliceous red sand dunes. Typically the dunes are orientated longitudinally. Other landscapes which have comparatively minor occurrences in the NT portion of this bioregion include the weathered tablelands with cracking-clay soils on Andado Station, the floodouts of major watercourses (including Illogwa Creek, the Todd, Finke, Hale and Hay Rivers) and the saline lake systems in the far south east of the study area near Poepples Corner. The vegetation of dune crests is commonly dominated by Sandhill Cane Grass (Zygochloa paradoxa) while the interdune areas support hummock grasslands (dominated by Triodia basedowii) with a sparse shrub overstorey of Acacia spp. and/or Grevillea spp. (Wilson et al 1990). A total of 118 indigenous vascular plant taxa are currently considered to be of conservation significance in the NT portion of the Simpson-Strzelecki Dunefields bioregion. These taxa are listed in volume 1, appendix 3.
