Made available via the Publications (Legal Deposit) Act 2004 (NT).; This report provides a benchmark for the conservation status of botanical values in the southern, predominantly arid part of the Northern Territory. It will have many and varied uses, providing information about conservation values to land holders and managers as well as government departments and conservation groups.

Volume 2, Part 2, page 308 Tanami Site: 21-4-4 Watt Range Floodouts and Fringing Sandplains Level of significance: bioregional Location: 21 39' S 134 15' E; Sandplains on the western margins of the Watts Range. Area: 303 km2 Map sheet: Barrow Creek SF 53-6 Bioregions: Tanami (TAN 76%) & Burt Plain (BRT 24%) Tenure: Freehold - Alyawarra Aboriginal Land Trust (18% of site); Pastoral Lease - Neutral Junction Station (64% of site), Stirling Station (<1% of site), Murray Downs (<1% of site) and Mount Skinner Station (16% of site) Description: Site is circumscribed rather arbitrarily. It includes the footslopes of the Watts Range, the floodouts on the plains beyond, and a 'tongue' of northwest-southeast oriented parallel dunes, which have botanical affinities with the central Tanami Desert. The sandplain is probably quite shallow in places and is underlain by Devonian sandstones. Values may extend to the south east towards the Sandover River, somewhat peripheral to the extent of outcropping Devonian geology. Notes: A rarely visited area. The sandplains support scattered Brachychiton gregorii and these stands extend in a broad band to the south east of the site. This species is a useful indicator of the availability of subsurface water resources and/or the proximity of porous sedimentary geologies. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: none Taxa of NT significance: Centipeda racemosa {3k}, Gymnanthera cunninghamii {3r}, Triumfetta johnstonii {3k} Taxa of Southern NT (study area) significance: Bothriochloa bladhii subsp. bladhii {(disjunct)} Taxa of bioregional significance: Acacia jensenii {BRT (disjunct) only known in BRT from this site}, Bergia ammannioides {BRT (apparently rare) only known in BRT from this site}, Corymbia sphaerica {BRT (southern range limit) [S]}, Dicrastylis lewellinii {TAN (northern range limit) [N]}, Gomphrena diffusa subsp. arenicola {TAN (southern and eastern range limit) [SE]}, Sida A88271 Rabbit Flat {TAN (eastern range limit) [E]} Other taxa only known in TAN bioregion (NT portion) from this site: Gossypium sturtianum var. sturtianum, Solanum coactiliferum Other taxa only known in BRT bioregion from this site: Fimbristylis depauperata Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 65 (2 %): Acacia aneura (Mulga) tall open-shrubland with Eragrostis eriopoda (Woolybutt) open-grassland understorey. Map unit 76 (90 %): Triodia pungens (Soft Spinifex), Triodia schinzii (Feathertop Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey. Map unit 43 (6 %): Eucalyptus low open-woodland and/or Acacia sparse-shrubland with Triodia spicata (Spike Flower Spinifex), Triodia pungens (Soft Spinifex) hummock grassland understorey.
