Volume 2, Part 2, page 298 Tanami Site: 20-1-4 Mongrel Downs Level of significance: bioregional Location: 20 31' S 129 14' E; Central Tanami Desert abutting the Western Australian border. Area: 758 km2 Map sheet: The Granites SF 52-03 Bioregion: Tanami (TAN) Tenure: Freehold - Mangkururrpa Aboriginal Land Trust (100% of site) Description: Site is centred on an outlier of clay soil in the Tanami desert, which supports extensive grasslands dominated by Eragrostis xerophila and Astrebla pectinata. The site also incorporates a paleodrainage system which extends to the north east and includes several large wetlands (Lake Sarah, Lake Alec and Bullocks Head Lake) and the series of laterite capped rises known as the Pedestal Hills. Notes: This site supports a number of interesting range disjunctions of species restricted to heavy soils. It is the only known location for an undescribed Ptilotus taxon. This site also includes the type location for Acacia pachycarpa. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: none Taxa of NT significance: Cleome oxalidea {3r}, Peplidium A88036 Tanami {3k} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Erodium cygnorum subsp. cygnorum {TAN (disjunct and northern range limit) [N] only known in TAN from this site}, Sclerolaena patenticuspis {TAN (disjunct and northern range limit) [N] only known in TAN from this site}, Swainsona burkei {TAN (western range limit) [W]}, Triglochin hexagonum {TAN (disjunct)} Other taxa only known in TAN bioregion (NT portion) from this site: Maireana integra, Sesbania cannabina var. sericea {only known in study area from this site} Type locations of the following were collected from the site: Acacia pachycarpa (1971) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 100 (68 %): Eragrostis xerophila (Neverfail) open-grassland with scattered trees and shrubs. Map unit 111 (3 %): Halosarcia (Samphire) low open-shrubland fringing bare salt pans. Map unit 76 (20 %): Triodia pungens (Soft Spinifex), Triodia schinzii (Feathertop Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey. Map unit 86 (8 %): Triodia pungens (Soft Spinifex) or Triodia basedowii (Hard Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey between dunes.
