Volume 2 , Part 2, page 174 MacDonnell Ranges Site: 23-3-2 Missionary Plain Level of significance: national Location: 23 49' S 132 11' E; ca. 50 km west of Hermannsberg Area: 2568 km2 Map sheets: Hermannsburg SF 53-13, Mount Liebig SF 52-16 & Henbury SG 53-1 Bioregions: MacDonnell Ranges (MAC 96.6%) & Great Sandy Desert (GSD 3.4%) Tenure: Freehold - Various Aboriginal Land Trusts (ABT), Haasts Bluff ABT (59% of site), Ltalaltuma ABT (31% of site) and Ntaria ABT (4% of site), Rodna ABT (3% of site); Tnorala (Gosse Bluff) Conservation Reserve (1% of site); West Mac. Nat. Park (<1%of site) Description: This site includes the western part of Missionary Plain, an extensive undulating sandplain bounded by the Macdonnell Ranges to the north and the Krichauff and Gardiner Ranges to the south. This plain is covered by a thin mantle of sand which covers mainly Devonian sandstones, which outcrop occasionally. The site has extensive areas of duricrust and alluvium which is associated with the creeks and rivers. The site includes the spectacular meteorite impact feature known as Gosses Bluff (Tnorala). Notes: This site is poorly known and botanical values may not be uniform across the site. Most of the records of interesting taxa are currently from accessible places such as Mount Katapata and Gosses Bluff. Shallow sand plains such as Missionary Plain which are 'perched' in the ranges have consistently different floristics than sandplains and dunefields with deeper sand. Such areas require further study. Describing and mapping the plant communities which occur in these areas should be a priority. Criteria satisfied: A1 bi), B1 b1 i) Taxa of Australian significance: Austrostipa aquarii {3RC-}, Comesperma viscidulum {3KC-}, Daviesia arthropoda {3KCa}, Logania centralis {3KC-}, Neurachne tenuifolia {3RCa [S]}, Pityrodia loricata {3K [E] only known in NT from this site} Taxa of NT significance: Agrostis avenacea {3rC-}, Calotis kempei {3k}, Elacholoma hornii {3rC-}, Eremophila ovata {3k [W] only known in GSD from this site}, Ixiolaena tomentosa {3kC-}, Laxmannia arida {3r}, Pimelea microcephala subsp. microcephala {3r}, Sclerolaena parviflora {3r}, Spartothamnella puberula {3rC-}, Vittadinia dissecta var. hirta {3kC-}, Vittadinia pustulata {3kC-}, Xanthorrhoea thorntonii {3rCa} Taxa of Southern NT (study area) significance: Adiantum hispidulum var. hispidulum {(disjunct)}, Bothriochloa bladhii subsp. bladhii {(disjunct)} Taxa of bioregional significance: Alectryon oleifolius subsp. elongatus {MAC (disjunct )}, Aristida biglandulosa {MAC (western range limit) [W]}, Atriplex humifusa {MAC (western range limit) [W]}, Eremophila christophori {MAC (western range limit) [W]}, Lechenaultia striata {GSD (northern range limit) [N]}, Lomandra leucocephala subsp. robusta {MAC (disjunct)}, Polycarpaea involucrata {MAC (disjunct ), GSD (disjunct)}, Vittadinia sulcata {MAC (disjunct)} Other taxa only known in MAC bioregion from this site: Goodenia modesta, Peplidium aithocheilum, Podolepis A96227 Wollunga Well Other taxa only known in GSD bioregion (NT portion) from this site: Paspalidium constrictum Type locations of the following were collected from the site: Anemocarpa saxatilis (1956), Corymbia eremaea subsp. oligocarpa (1972) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 92 (1 < %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey. Map unit 81 (29 %): Triodia basedowii (Hard Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey. Map unit 93 (39 %): Triodia basedowii (Hard Spinifex) hummock grassland with Allocasuarina decaisneana (Desert Oak) openwoodland overstorey between dunes. Map unit 71 (17 %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey. Map unit 87 (1 < %): Triodia (Spinifex) open-hummock grassland with Acacia aneura tall sparse-shrubland overstorey. Map unit 68 (10 %): Acacia kempeana (Witchetty Bush) Acacia tall open-shrubland with Senna, Eremophila (Fuchsia) openshrubland understorey.
