Volume 2, Part 2, page 260 Simpson-Strzelecki Dunefields Site: 24-6-1 Prior floodout of the Plenty River Level of significance: bioregional Location: 24 14' S 136 34' E; North West Simpson Desert Area: 923 km2 Map sheets: Simpson Desert North SG 53-4 & Hale River SG 53-3 Bioregion: Simpson-Strzelecki Dunefields (SSD) Tenure: Vacant Crown Land (99% of site); Freehold - Atnetye Aboriginal Land Trust (<1% of site) Description: This site encloses a series of lakes which possibly denotes the paleo-floodout of the Plenty River. The site includes extensive areas of lakes and interdune claypans, dunefields, evaporite deposits (principally calcrete and gypsum) and alluvium, with minor outcroppings of cretaceous marine sediments (sandstones, limestone, siltstones and mudstones) and tertiary siltstone. Notes: The site supports extensive but disjunct woodlands/shrublands of Acacia georginae and Acacia aneura. The numerous ephemeral lakes and playas are of varying salinity. This remote region has only been visited occasionally by botanists. Criteria satisfied: A1a ii), B1 b1 ii) Taxa of Australian significance: none Taxa of NT significance: Atriplex eardleyae {3r [N]}, Bulbine alata {3k}, Calandrinia polyandra {3kC-}, Cullen discolor {3k}, Frankenia cupularis {3r only known in NT from this site}, Glinus orygioides {3r}, Ixiochlamys nana {3kC-}, Maireana appressa {3k}, Swainsona laxa {3r}, Trichanthodium skirrophorum {3kC-} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Blennodia pterosperma {SSD (northern range limit) [N]}, Swainsona unifoliolata {SSD (disjunct and eastern range limit) [E] only known in SSD from this site}, Triumfetta winneckeana {SSD (disjunct)} Other taxa only known in SSD bioregion (NT portion) from this site: Ptilotus exaltatus var. glaber {[S]}, Solanum cleistogamum, Zygophyllum aurantiacum subsp. aurantiacum, Zygophyllum compressum Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 109 (28 %): Chenopod open-herbland with ephemeral open-herb/grassland. Map unit 71 (6 %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey. Map unit 111 (12 %): Halosarcia (Samphire) low open-shrubland fringing bare salt pans. Map unit 63 (17 %): Acacia georginae (Gidyea) low open-woodland with open-grassland understorey. Map unit 85 (34 %): 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.
