Volume 2 , Part 2, page 184 MacDonnell Ranges Site: 23-4-5 Trephina Level of significance: national Location: 23 33' S 134 28' E; East MacDonnell Ranges; extending from just over 20 km east of Alice Springs to 100 km north-east of Alice Springs. Area: 563 km2 Map sheet: Alice Springs SF 53-14 Bioregions: MacDonnell Ranges (MAC 99.3%) & Simpson-Strzelecki Dunefields (SSD 0.7%) Tenure: Pastoral lease - Undoolya (16%), The Garden (45%), Loves Creek (22%) and Ambalindum (<1%) Stations; Trephina Gorge Nat. Park (3%); Arltunga Hist. Res. (4%); Freehold - Psanye and Melknge Aboriginal Land Trusts (both <1%), Other Freehold (5%) Description: This large site incorporates much of the Heavitree Quartzite ranges of the East Macdonnell Ranges, and is roughly centred on Trephina Gorge Nature Park. It also incorporates part of Arltunga Historical Reserve in the north-east of the site. Other sediments of the Amadeus Basin sequence, of which Heavitree Quartzite is the oldest, occur in the site, including Bitter Springs Limestone. Notes: Five plant species listed as nationally Vulnerable are found in the site as well as three nationally rare species, four species that are rare in the NT and 6 poorly known taxa. Records of these taxa are spread across the site, with few of the species cooccurring in one spot. The unifying feature is the landform and geology, which encompass a number of gorges, waterholes, and rivers in addition to the ranges which define the site. Several taxa are at or near the edge of their known range in the site. The site includes the type locations for Amyema subcapitata (not recognised as a distinct species), Minuria tridens and Corymbia opaca. Criteria satisfied: B1 b2 i), B1 b1 i) Taxa of Australian significance: Acacia undoolyana {2VCi [NSEW]}, Callistemon pauciflorus {3RC- [NE]}, Hakea grammatophylla {3RC-}, Macrozamia macdonnellii {3VCa}, Minuria tridens {3VCi}, Olearia macdonnellensis {3VCi [E]}, Ricinocarpos gloria-medii {2VCa [NS]}, Sedopsis filsonii {3RC-}, Sida A43017 Ambalindum {3KC-} Taxa of NT significance: Arabidella trisecta {3kC-}, Calotis kempei {3k}, Crotalaria dissitiflora var. dissitiflora {3k}, Eremophila elderi {3k}, Eucalyptus thozetiana {3rC- [W]}, Hibiscus sturtii var. sturtii {3rC-}, Lythrum paradoxum {3k}, Maireana carnosa {3rC-}, Spartothamnella puberula {3rC-} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Austrostipa scabra subsp. scabra {MAC (disjunct)}, Baeckea polystemonea {MAC (eastern range limit) [E]}, Convolvulus remotus {MAC (disjunct)}, Cyanthillium cinereum s.lat. {MAC (disjunct)}, Iseilema macratherum {MAC (disjunct and apparently rare) only known in MAC from this site}, Juncus A87739 MacDonnell Ranges {MAC (northern and eastern range limits) [NE]}, Radyera farragei {MAC (disjunct)}, Rotala occultiflora {MAC (disjunct)}, Trema tomentosa var. viridis {MAC (disjunct)} Other taxa only known in MAC bioregion from this site: Atriplex vesicaria subsp. variabilis, Eriochloa australiensis, Ptilotus helipteroides var. minor, Triodia triaristata {[S]} Type locations of the following were collected from the site: Amyema subcapitata, Minuria tridens (1983) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 65 (1 < %): Acacia aneura (Mulga) tall open-shrubland with Eragrostis eriopoda (Woolybutt) open-grassland understorey. Map unit 71 (1 %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey.

Map unit 68 (17 %): Acacia kempeana (Witchetty Bush) Acacia tall open-shrubland with Senna, Eremophila (Fuchsia) openshrubland understorey. Map unit 92 (50 %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey. Map unit 80 (25 %): Triodia longiceps (Bull Spinifex) hummock grassland with Acacia tall open-shrubland overstorey. Map unit 59 (4 %): Acacia estrophiolata (Ironwood), Atalaya hemiglauca (Whitewood) low open-woodland with open-grassland understorey.
