Volume 2, Part 2, page 304 Tanami Site: 20-5-4 Wonarah Beds Level of significance: bioregional Location: 19 56' S 136 19' E; Wakaya Desert Area: 1431 km2 Map sheets: Frew River SF 53-03, Ranken SE 53-16 & Alroy SE-53-15 Bioregions: Tanami (TAN 98.5%) & Mitchell Grass Downs (MGD 1.5%) Tenure: Freehold - Arruwurra Aboriginal Corporation (35% of site), Wakaya Aboriginal Land Trust (21% of site); Pastoral Lease - Dalmore Downs Station (38% of site), West Ranken Station (4% of site); Crown land (<1% of site) Description: Comprises part of an extensive area characterised by the outcropping of the Wonarah Beds - low rises of chert chalcedony, tertiary travertine, silicified coquinite and limestone, and outcrops of Cambrian dolomite framed in a sandplain. The beds occur over a very large area and values of this site may not be unique or may extend over a much larger region. Notes: This distinctive undulating desert landscape is unique to this area of the Wakaya desert. The only known collection of Sporobolus latzii has been made from this site. In addition, the site is the type location for Acacia drepanocarpa subsp. latifolia. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: Bonamia alatisemina {3K [E]}, Rothia indica subsp. australis {3KC-}, Sporobolus latzii {1K [NSEW] endemic to/only known from this site} Taxa of NT significance: Distichostemon barklyanus {3k}, Heliotropium ballii {3k}, Heliotropium pulvinum {3K}, Najas marina {3rC- only known in TAN from this site}, Triumfetta centralis {3k}, Triumfetta deserticola {3k} Taxa of Southern NT (study area) significance: Grevillea dryandri subsp. dryandri {(disjunct)} Taxa of bioregional significance: Eragrostis olida {TAN (eastern range limit) [E]}, Exocarpos sparteus {TAN (northern range limit) [N]}, Isoetes muelleri {TAN (disjunct and apparently rare) only known in TAN from this site}, Tephrosia stuartii {TAN (eastern range limit) [E]} Type locations of the following were collected from the site: Acacia drepanocarpa subsp. latifolia (1960), Sporobolus latzii Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 42 (94 %): Corymbia opaca (Bloodwood) low open-woodland with Triodia pungens (Soft Spinifex) hummock grassland understorey. Map unit 96 (1 < %): Astrebla pectinata (Barley Mitchell grass) grassland. Map unit 107 (1 %): Chenopodium auricomum (Bluebush) low open-shrubland with ephemeral grassland understorey. Map unit 41 (4 %): Corymbia opaca (Bloodwood) low open-woodland with Triodia bitextura (Curly Spinifex) hummock grassland understorey.
