Made available via the Publications (Legal Deposit) Act 2004 (NT).; This report provides a benchmark for the conservation status of botanical values in the southern, predominantly arid part of the Northern Territory. It will have many and varied uses, providing information about conservation values to land holders and managers as well as government departments and conservation groups.

Volume 2 , Part 2, page 206 MacDonnell Ranges Site: 23-4-11 Mount Riddock Level of significance: bioregional Location: 23 4' S 134 38' E; ca 100 km north east of Alice Springs Area: 47 km2 Map sheet: Alice Springs SF 53-14 Bioregions: Burt Plain (BRT 98%) & MacDonnell Ranges (MAC 2%) Tenure: Pastoral Lease - Mount Riddock Station (100% of site) Description: This site includes the Mount Riddock massif and associated hills, footslopes and some of the surrounding plains. Mount Riddock is composed of amphibolite, a rock type rich in dark mafic minerals. This site is part of the greater Macdonnell Ranges area, however, it is currently located in the Burt Plain bioregion. This is a consequence of the scale at which the bioregional boundary was prepared and digitised. Notes: The mineralogy of this site is similar to the nearby Harts Range site (see site 23-4-9). It supports populations of several rare and poorly known plant species and potentially supports interesting and possibly rare plant communities. The southern fall of the range has associations of 'fire sensitive' vegetation. The site also includes the type locations for Austrostipa centralis and Aristida latzii. Criteria satisfied: B1 b1 ii), C1 b ii) Taxa of Australian significance: Austrostipa centralis {3RC-},Gossypium nelsonii {3RC-} Taxa of NT significance: Eremophila elderi {3k} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Brachycome blackii {BRT (northern range limit) [N] only known in BRT from this site}, Corymbia eremaea subsp. eremaea {MAC (northern range limit) [N] only known in BRT from this site}, Vittadinia sulcata {MAC (disjunct), BRT (disjunct)} Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 58 (24 %): Acacia aneura (Mulga)/mixed species low open-woodland with open-grassland understorey. Map unit 68 (14 %): Acacia kempeana (Witchetty Bush) Acacia tall open-shrubland with Senna, Eremophila (Fuchsia) openshrubland understorey. Map unit 59 (60 %): Acacia estrophiolata (Ironwood), Atalaya hemiglauca (Whitewood) low open-woodland with open-grassland understorey.
