Volume 2 , Part 2, page 186 MacDonnell Ranges Site: 23-4-6 N'Dhala Level of significance: national Location: 23 40' S 134 29' E; ca. 50 km east of Alice Springs. Area: 484 km2 Map sheet: Alice Springs SF 53-14 Bioregion: MacDonnell Ranges (MAC) Tenure: Pastoral lease - Undoolya (39% of site), The Garden (4% of site) and Loves Creek (54% of site) Stations; N'Dhala Gorge Nature Park (1% of site); Arltunga Hist. Res. (4%); Freehold - Psanye and Melknge Aboriginal Land Trusts, other freehold Description: This site in the east Macdonnell Ranges is bounded in the north by the Ross River and Goat Camp Creek, to the east by Giles Creek, to the west by Williams Creek and to the south by exposures of the Arumbera Sandstone, which effectively marks the edge of the surrounding flood plains of the Todd and Ross Rivers. The site is centred on two striking geological features - the Ross River Syncline and the Fergusson Syncline. Thick somewhat concentric bands of Devonian and Cambrian sediments enclose small plains and pounds with alluvial soils. Notes: The area supports a suite of rare plant taxa and at least one rare plant community - shrublands dominated by Acacia undoolyana. The site is of major importance in the conservation of the threatened plant species Acacia undoolyana and Ricinocarpos gloria-medii. Most of the known botanical values of the site are centred in the western portion of the site (west of the Ross River). The eastern section of the site (east of the Ross River) has had limited botanical exploration and values here are implied from geomophology. The site includes the type location for Acacia undoolyana. Criteria satisfied: B1 b2 i), B1 b1 i) Taxa of Australian significance: Acacia undoolyana {2VCi [NSEW]}, Austrostipa centralis {3RC-}, Phyllanthus oblanceolatus {3KC- [N]}, Ricinocarpos gloria-medii {2VCa [SE]}, Samolus eremaeus {3KC-}, Sedopsis filsonii {3RC-} Taxa of NT significance: Bulbostylis pyriformis {3rC-}, Eucalyptus thozetiana {3rC-}, Hibiscus sturtii var. sturtii {3rC-}, Lythrum paradoxum {3k}, Sida A71181 Bond Springs {3kC- only known in MAC from this site}, Sida A90797 Rainbow Valley {3kC-}, Spartothamnella puberula {3rC-} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Austrostipa scabra subsp. scabra {MAC (disjunct)}, Canthium lineare {MAC (eastern range limit) [E]}, Convolvulus remotus {MAC (disjunct)}, Rulingia magniflora {MAC (northern range limit) [N]}, Swainsona canescens {MAC (eastern range limit) [E]}, Trema tomentosa var. viridis {MAC (disjunct)} Type locations of the following were collected from the site: Acacia undoolyana (1987) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 92 (50 %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey. Map unit 80 (33 %): Triodia longiceps (Bull Spinifex) hummock grassland with Acacia tall open-shrubland overstorey. Map unit 66 (15 %): Acacia aneura (Mulga) tall open-shrubland with Senna, Eremophila (Fuchsia) open-shrubland understorey.
