Volume 2 , Part 2, page 180 MacDonnell Ranges Site: 23-4-14 Simpsons Gap Level of significance: national Location: 23 32' S 133 43' E; ca. 20 km west of Alice Springs. Area: 94 km2 Map sheet: Alice Springs SF 53-14 Bioregion: MacDonnell Ranges (MAC) Tenure: West MacDonnell National Park (78% of site); Freehold - Iwupataka Aboriginal Land Trust (21% of site) Description: The site incorporates much of the upper part of the catchment of Roe Creek. The site is bounded to the north by the outcropping of meta-sandstone geologies. The botanical values of the site are enhanced by the steep sheltered south facing slopes and the series of deep gorges (including the spectacular Simpson's Gap) cut down through the quartzite strike ridges. Other features of botanical interest are the extensive stands of mature Mulga (Acacia aneura) and small areas of outcropping metamorphic rocks rich in the mineral amphibolite - which weather to produce fertile soils. Notes: The site is rich in plant taxa with over 430 species recorded (Gibson et al. 1990). Type locality for Calandrinia reticulata, Crassula sieberiana subsp. tetramera and Ricinocarpos gloria-medii. Criteria satisfied: B1 b1 i), A1 c i) Taxa of Australian significance: Austrostipa feresetacea {3RC- [S]}, Pluchea A87409 Ormiston {3K [S]}, Ricinocarpos gloriamedii {2VCa [SW]}, Samolus eremaeus {3KC-} Taxa of NT significance: Corchorus pumilio {3kC-}, Einadia nutans subsp. nutans {3rC-}, Enneapogon intermedius {3k}, Harmsiodoxa puberula {3rC-}, Ixiochlamys nana {3kC-}, Ophioglossum lusitanicum {3rC-}, Ophioglossum polyphyllum {3rC-}, Oxalis radicosa {3kC-}, Parietaria cardiostegia {3r}, Phyllanthus erwinii {3k}, Senecio cunninghamii var. serratus {3r}, Spartothamnella puberula {3rC-}, Tricoryne elatior s.lat. {3rC-}, Triumfetta centralis {3k only known in MAC from this site} Taxa of Southern NT (study area) significance: Plumbago zeylanica {(disjunct)} Taxa of bioregional significance: Austrostipa scabra subsp. scabra {MAC (disjunct)}, Convolvulus remotus {MAC (disjunct)}, Crassula colorata var. acuminata {MAC (northern range limit) [N]}, Persicaria lapathifolia {MAC (disjunct)}, Radyera farragei {MAC (disjunct)}, Trema tomentosa var. viridis {MAC (disjunct)}, Vittadinia sulcata {MAC (disjunct)} Other taxa only known in MAC bioregion from this site: Brachyachne ciliaris Type locations of the following were collected from the site: Calandrinia reticulata (1974), Crassula sieberiana subsp. tetramera (1973), Ricinocarpos gloria-medii (1972) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 68 (2 %): Acacia kempeana (Witchetty Bush) Acacia tall open-shrubland with Senna, Eremophila (Fuchsia) openshrubland understorey. Map unit 66 (3 %): Acacia aneura (Mulga) tall open-shrubland with Senna, Eremophila (Fuchsia) open-shrubland understorey. Map unit 87 (8 %): Triodia (Spinifex) open-hummock grassland with Acacia aneura tall sparse-shrubland overstorey.
