Volume 2, Part 2, page 158 Great Sandy Desert Site: 25-2-2 Kata Tjuta Level of significance: bioregional Location: 25 17' S 130 44' E; Amadeus or Great Sandy Desert - ca. 25 km WSW of Yulara. Area: 165 km2 Map sheet: Ayres Rock SG 52-8 Bioregion: Great Sandy Desert (GSD) Tenure: Freehold - Katiti Aboriginal Land Trust (12% of site), Petermann Aboriginal Land Trust (10% of site), Uluru Kata Tjuta Aboriginal Land Trust (leased and reserved under the Commonwealth National Parks Act) (76% of site) Description: The site is centred on the series of conglomerate inselbergs which comprise Kata Tjuta. These have weathered to form unusual dome like structures. The site includes these structures and the surrounding run-on areas and watercourses which drain Kata Tjuta following rain. Large expanses of impervious rock drain onto relatively sheltered valleys and floodouts where moisture may persist for extended periods. Notes: Kata Tjuta is an important area in the history of botanical exploration in Australia's arid zone. It is the type locality for several plant taxa including Ptilotus exaltatus var. pallidus, Eriachne scleranthoides, Ptilotus obovatus var. griseus, Wurmbea centralis and Wurmbea centralis subsp. centralis (see below for complete listing). Criteria satisfied: A1a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: Acacia ammobia {3RC-}, Eriachne scleranthoides {2RCa [SE]}, Wurmbea centralis subsp. centralis {3RC- [N]} Taxa of NT significance: Heliotropium inexplicitum {3k}, Hibbertia glaberrima {3rCa only known in GSD from this site}, Isotropis centralis {3rC-}, Maireana lanosa {3rC-}, Olearia arida {3k only known in NT from this site}, Ophioglossum polyphyllum {3rC-}, Senna artemisioides subsp. glaucifolia {3r only known in GSD from this site}, Sida A59261 Kathlene Springs {3kC-}, Sida calyxhymenia {3r}, Swainsona tenuis {3kC-}, Vittadinia pustulata {3kC- only known in GSD from this site} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Gomphrena canescens subsp. canescens {GSD (disjunct and southern range limit) [S]}, Indigofera leucotricha {GSD (disjunct)}, Isotropis wheeleri {GSD (western range limit) [W] only known in GSD from this site}, Nicotiana excelsior {GSD (apparently rare) only known in GSD from this site} Other taxa only known in GSD bioregion (NT portion) from this site: Amaranthus mitchellii, Aristida obscura, Chenopodium desertorum subsp. rectum, Codonocarpus cotinifolius, Cyperus victoriensis, Eragrostis parviflora, Lepidium oxytrichum, Maireana planifolia, Marsilea exarata, Panicum laevinode, Phyllanthus lacunellus, Ptilotus exaltatus var. pallidus {[N] only known in NT from this site}, Ptilotus obovatus var. griseus, Ptilotus sessilifolius var. elderi, Rulingia magniflora, Stemodia viscosa, Triodia irritans Type locations of the following were collected from the site: Dicrastylis gilesii var. gilesii (1870s), Eriachne scleranthoides, Haloragis gossei (1870s), Lechenaultia striata (1870s), Paraceterach reynoldsii, Prostanthera wilkieana (1873), Ptilotus exaltatus var. pallidus, Ptilotus obovatus var. griseus (1959), Ptychosema anomalum (1870s), Rhodanthe tietkensii, Rulingia magniflora (1870s), Schoenia ayersii (1873), Wurmbea centralis subsp. centralis (1955) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 90 (59 %): Triodia irritans (Porcupine Grass) open-hummock grassland. Map unit 93 (10 %): Triodia basedowii (Hard Spinifex) hummock grassland with Allocasuarina decaisneana (Desert Oak) openwoodland overstorey between dunes. Map unit 65 (6 %): Acacia aneura (Mulga) tall open-shrubland with Eragrostis eriopoda (Woolybutt) open-grassland understorey. Map unit 82 (23 %): Triodia basedowii (Hard Spinifex)hummock grassland with Acacia aneura (Mulga) tall sparse-shrubland overstorey between dunes.
