Volume 2 , Part 2, page 204 MacDonnell Ranges Site: 23-4-10 Hale and Paddys Plains Level of significance: bioregional Location: 23 25' S 134 35' E; ca. 90 km north east of Alice Springs. Area: 491 km2 Map sheet: Alice Springs SF 53-14 Bioregion: MacDonnell Ranges (MAC) Tenure: Pastoral Lease - Ambalindum Station (35% of site), Loves Creek Station (10% of site) and The Garden Station (51% of site); Arlunga Historical Reserve (2% of site) Description: This site includes two peneplains enclosed within the east Macdonnell Ranges, delineated by two discrete polygons. The plains also encompass low hills composed of tertiary material, primarily silcrete, limestone and siltstone and minor outcroppings of gneiss. The weathering of the surrounding crystalline metamorphic rocks and tertiary sediments has given rise to calcareous clay-rich soils. Notes: Heavy clay soils are uncommon in this and adjoining bioregions. As such, the site is an important area for disjunctions of plant taxa reaching the northern or southern edge of their continental range. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: Cratystylis A36062 Glen Helen {3RC-}, Ixiochlamys integerrima {3K only known in MAC from this site}, Sedopsis filsonii {3RC-}, Sida A43017 Ambalindum {3KC-} Taxa of NT significance: Astrebla lappacea {3k}, Eriochiton sclerolaenoides {3k [N]}, Eucalyptus thozetiana {3rC- [W]}, Maireana schistocarpa {3k} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Aristida strigosa {MAC (northern range limit)[N]},Atriplex nummularia subsp. nummularia {MAC (northern range limit) [N]}, Cyanthillium cinereum s.lat. {MAC (disjunct)}, Heliotropium conocarpum {MAC (disjunct and southern range limit) [S] only known in MAC from this site}, Vittadinia sulcata {MAC (disjunct)} Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 92 (17 %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey. Map unit 59 (54 %): Acacia estrophiolata (Ironwood), Atalaya hemiglauca (Whitewood) low open-woodland with open-grassland understorey. Map unit 68 (26 %): Acacia kempeana (Witchetty Bush) Acacia tall open-shrubland with Senna, Eremophila (Fuchsia) openshrubland understorey. Map unit 66 (1 < %): Acacia aneura (Mulga) tall open-shrubland with Senna, Eremophila (Fuchsia) open-shrubland understorey. Map unit 80 (1 < %): Triodia longiceps (Bull Spinifex) hummock grassland with Acacia tall open-shrubland overstorey.
