Volume 2, Part 2, page 114 Finke Site: 24-4-4 Ooraminna Level of significance: national Location: 24 5' S 134 2' E; Approximately 45km south of Alice Springs. Area: 253 km2 Map sheet: Rodinga SG 53-2 Bioregion: Finke (FIN) Tenure: Pastoral Lease - Deepwell Station (71% of site), Orange Creek (9% of site), Owen Springs (7% of site); Crown Lease - Ghan Preservation Society (11% of site) Description: Includes the outcropping sequence of sedimentary rocks associated with the Ooraminna anti-cline and the surrounding outwash plains underlain by porous sandstone geologies and minor exposures of the same. Of particular note is the prominence of Devonian sandstones in the outcropping rocks (ie Hermannsburg and Mereenie sandstones). To the south the site is bounded by a series of east-west oriented travertine outcrops. Notes: This site supports a high number of rare and threatened plant taxa and possibly rare plant communities as evidenced by the presence of mature stands of Brachychiton gregorii, which grow on the sandplains to the east and west of the site. The site is of particular note for the presence of two of the three known sites for the vulnerable Eremophila A48866 Rainbow Valley. One of these sites, found recently, is the largest currently known and supports many hundreds of plants. The site also incorporates the type localities of both Aristida arida and Cullen pallidum. Criteria satisfied: B1 b1 i) Taxa of Australian significance: Eremophila A48866 Rainbow Valley {2VCi [NE] only known in FIN from this site}, Harnieria kempeana subsp. kempeana {3RC- only known in FIN from this site}, Sedopsis filsonii {3RC- only known in FIN from this site} Taxa of NT significance: Calotis cymbacantha {3kC- [N]}, Corynotheca licrota {3rC- [N]}, Goodenia havilandii {3rC-}, Parietaria cardiostegia {3r}, Zygophyllum rowelliae {3k} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Brachychiton gregorii {FIN (apparently rare)}, Eucalyptus mannensis {FIN (eastern range limit) [E]} Other taxa only known in FIN bioregion (NT portion) from this site: Acacia coriacea subsp. sericophylla, Dicrastylis lewellinii, Eragrostis cumingii, Mollugo cerviana, Ozothamnus kempei, Panicum effusum, Pleurosorus rutifolius, Pluchea dunlopii, Vigna lanceolata var. latifolia Type locations of the following were collected from the site: Aristida arida (1956), Cullen pallidum (1955) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 72 (1 < %): Acacia kempeana (Witchetty Bush) sparse-shrubland to tall sparse-shrubland with grassland understorey. Map unit 66 (48 %): Acacia aneura (Mulga) tall open-shrubland with Senna, Eremophila (Fuchsia) open-shrubland understorey. Map unit 71 (23 %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey. Map unit 83 (28 %): Triodia basedowii (Hard Spinifex) or Triodia pungens (Soft Spinifex) hummock grassland with Eucalyptus gamophylla (Blue Mallee), Acacia tall sparse-shrubland overstorey.
