Volume 2, Part 2, page 146 Great Sandy Desert Site: 22-2-2 Central Mount Wedge Level of significance: bioregional Location: 22 49' S 131 53' E; ca. 5 km south of Yuendumu. Area: 232 km2 Map sheet: Mount Doreen SF 52-12 Bioregion: Great Sandy Desert (GSD) Tenure: Crown Freehold (Central Mount Wedge) (100% of site) Description: This site incorporates the Stuart Bluff Range, which rises in places (notably central Mount Wedge) to over 1000 m - some 400-500 m above the surrounding plains. The site includes alluvial fans and run on areas associated with the range. The western border of the site is formed be the 'shoreline' of a sub-linear saline lake system to the west of central Mount Wedge. The Stuart Bluff Range is composed of quartzite and contains several deep gorges. Notes: This site supports a diversity of contrasting habitats within a relatively discrete area. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: none Taxa of NT significance: Eragrostis crateriformis {3k [E] only known in NT from this site}, Halosarcia halocnemoides subsp. tenuis {3k}, Heliotropium epacrideum {3k}, Lawrencia squamata {3k}, Swainsona cyclocarpa {3k}, Triumfetta johnstonii {3k only known in GSD from this site}, Triumfetta maconochieana {3k only known in GSD from this site} Taxa of Southern NT (study area) significance: Adiantum hispidulum var. hispidulum {(disjunct) only known in GSD from this site} Taxa of bioregional significance: Goodenia maideniana {GSD (disjunct)}, Swainsona tanamiensis {GSD (disjunct and southern range limit) [S]}, Trema tomentosa var. viridis {GSD (disjunct)} Other taxa only known in GSD bioregion (NT portion) from this site: Maireana integra Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 78 (51 %): Triodia spicata (Spike-flowered Spinifex) hummock grassland with Grevillea wickhamii (Holly Grevillea), Acacia sparse-shrubland overstorey. Map unit 81 (1 < %): Triodia basedowii (Hard Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey. Map unit 65 (32 %): Acacia aneura (Mulga) tall open-shrubland with Eragrostis eriopoda (Woolybutt) open-grassland understorey. Map unit 93 (12 %): Triodia basedowii (Hard Spinifex) hummock grassland with Allocasuarina decaisneana (Desert Oak) openwoodland overstorey between dunes. Map unit 71 (1 < %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey. Map unit 72 (2 %): Acacia kempeana (Witchetty Bush) sparse-shrubland to tall sparse-shrubland with grassland understorey.
