Volume 2 , Part 2, page 196 MacDonnell Ranges Site: 24-4-5 Rainbow Valley Level of significance: national Location: 24 18' S 133 30' E; Central James Range in the greater Macdonnell Ranges. Area: 319 km2 Map sheets: Rodinga SG 53-2 & Henbury SG 53-1 Bioregions: MacDonnell Ranges (MAC 97.1%) & Finke (FIN 2.9%) Tenure: Rainbow Valley Conservation Reserve (6% of site); Pastoral Lease - Orange Creek Station (84% of site), Owen Springs Station (8% of site); Freehold Pwerte Marnte Marnte Aboriginal Corporation (1% of site) Description: Includes the James Ranges, outwash plains and adjacent inselbergs between John Hollands bore and the Hugh River. The site approximates the extent of outcropping porous sandstone geologies - Hermannsburg and Mereenie Sandstones. The protracted weathering of the Hermannsburg sandstone has resulted in the formation of isolated mesas on the northern side of the range, including the spectacular Rainbow Valley. Notes: The site is physiographically and edaphically heterogeneous. Broad habitat types relevant to the presence of rare plants includes rocky ridge-lines, gorges, run-on areas and freshwater, shallow sand sheets over limestone and sub-saline claypans. Criteria satisfied: B1 b1 i) Taxa of Australian significance: Daviesia arthropoda {3KCa}, Eremophila A48866 Rainbow Valley {2VCi [NSW] only known in MAC from this site}, Zygophyllum crassissimum {3KC-} Taxa of NT significance: Amyema miraculosa subsp. boormanii {3k}, Atriplex sturtii {3rC- [N] only known in NT from this site}, Eriochiton sclerolaenoides {3k}, Paractaenum novae-hollandiae subsp. reversum {3kC-}, Pomax A89438 Sand Dunes {3kC-}, Sauropus rigens {3rC-}, Senna phyllodinea {3k only known in MAC from this site}, Sida A90797 Rainbow Valley {3kC-} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Alectryon oleifolius subsp. elongatus {MAC (disjunct )}, Dampiera cinerea {eastern range limit [E]}, Josephinia eugeniae s.lat. {MAC (disjunct)}, Tecticornia verrucosa {MAC (eastern range limit) [E] only known in MAC from this site}, Trema tomentosa var. viridis {MAC (disjunct)} Other taxa only known in MAC bioregion from this site: Acacia dictyophleba, Zygophyllum howittii Other taxa only known in FIN bioregion (NT portion) from this site: Boerhavia repleta, Cremnothamnus thomsonii, Oldenlandia pterospora Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 71 (3 %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey. Map unit 83 (6 %): Triodia basedowii (Hard Spinifex) or Triodia pungens (Soft Spinifex) hummock grassland with Eucalyptus gamophylla (Blue Mallee), Acacia tall sparse-shrubland overstorey. Map unit 87 (76 %): Triodia (Spinifex) open-hummock grassland with Acacia aneura tall sparse-shrubland overstorey. Map unit 92 (1 < %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey. Map unit 66 (13 %): Acacia aneura (Mulga) tall open-shrubland with Senna, Eremophila (Fuchsia) open-shrubland understorey.
