Volume 2, Part 2, page 258 Simpson-Strzelecki Dunefields Site: 24-5-3 Old Todd River Floodout Level of significance: bioregional Location: 24 41' S 135 15' E; North west Simpson Desert Area: 948 km2 Map sheet: Hale River SG 53-3 Bioregion: Simpson-Strzelecki Dunefields (SSD) Tenure: Pastoral Lease - Andado Station (100% of site) Description: The site approximates the extent of an old floodout (presumed) of the Todd River, which now empties into the Simpson Desert to the north east. The site is primarily recent aeolian sands, alluvium and lenses of river gravels. There are numerous interdune claypans and more extensive systems of playas where past flooding has broken through the NNW oriented parallel dunes. Running through the site roughly oriented NE-SW are a series of low outcrops of sandstone, mudstone and conglomerate, which once impeded the floodwaters of the Todd River from draining to the south. Notes: The area is remote and rarely visited. A high percentage of the limited number of botanical collections are of some conservation interest. The site still receives some subsurface drainage and supports a diversity of habitats and plant communities. Criteria satisfied: B1 b1 ii) Taxa of Australian significance: none Taxa of NT significance: Atriplex eardleyae {3r}, Bulbine alata {3k}, Gilesia biniflora {3k}, Osteocarpum acropterum var. acropterum {3k only known in SSD from this site} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Acacia paraneura {SSD (apparently rare) only known in SSD from this site}, Bergia ammannioides {SSD (disjunct)}, Peplidium muelleri {SSD (apparently rare) only known in SSD from this site} Other taxa only known in SSD bioregion (NT portion) from this site: Calandrinia eremaea, Lysiana subfalcata, Sida platycalyx, Stackhousia intermedia Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 61 (3 %): Complex of mixed species low open-woodland between dunes with Zygochloa paradoxa (Sandhill Cane Grass) open-hummock grassland on dune crests. Map unit 85 (96 %): Triodia basedowii (Hard Spinifex) hummock grassland with Acacia tall sparse shrubland overstorey between dunes and Zygochloa paradoxa (Sandhill Cane Grass) open-hummock grassland on dune crests.
