Volume 2, Part 2, page 52 Burt Plain Site: 22-5-2 Dulcie Ranges Level of significance: national Location: 22 35' S 135 39' E; Extensive area of low ranges, ca. 220 km north east of Alice Springs. Area: 1117 km2 Map sheet: Huckitta SF 53-11 Bioregion: Burt Plain (BRT) Tenure: Dulcie Ranges National Park (12% of site); Pastoral Lease - Arapunya Station (29% of site), Dneiper Station (<1% of site), Huckitta Station (24% of site) and Jinka Station (32% of site) Description: The site incorporates much of the central Dulcie Range an extensive but isolated sandstone upland. The site includes the upper reaches of the catchments of Ooratippra, Oomoolmilla, Oorabra and Yam Creeks. Notes: The Dulcie Range is biogeographically significant and supports many rare and disjunct populations of plant taxa. The botanical values of this site are centred on the sandstone gorges within the ranges and their numerous permanent and semipermanent waterholes and spring fed rockholes. The site also supports good populations of the rare Cratystylis A36062 Glen Helen. The south western foothills of the Dulcie Ranges support interesting shrublands dominated by Eremophila dalyana. Criteria satisfied: A1 a i), A1 b i), A2 e i), A1 c i) , B1 b1 i) Taxa of Australian significance: Cratystylis A36062 Glen Helen {3RC- [NE]}, Samolus eremaeus {3KC-}, Stylidium inaequipetalum {3RCa [E] only known in BRT from this site} Taxa of NT significance: Eragrostis A51007 Limestone {3k}, Eremophila dalyana {3rC-}, Juncus continuus {3rC- only known in BRT from this site}, Sida D70364 Huckitta {3k only known in BRT from this site}, Spartothamnella puberula {3rC-} Taxa of Southern NT (study area) significance: Fimbristylis sieberana {(disjunct) only known in BRT from this site}, Imperata cylindrica {(disjunct & apparently rare) only known in BRT from this site}, Psilotum nudum {(rare) only known in BRT from this site}, Schoenus falcatus {(disjunct & apparently rare) only known in BRT from this site} Taxa of bioregional significance: Acacia macdonnelliensis subsp. macdonnelliensis {BRT (eastern range limit) [E]}, Aristida arida {BRT (northern range limit) [N]}, Cremnothamnus thomsonii {BRT (eastern range limit) [E]}, Cyanthillium cinereum s.lat. {BRT (disjunct)}, Kennedia prorepens {BRT (disjunct and apparently rare)}, Lepidium oxytrichum {BRT (northern range limit) [N]}, Myoporum acuminatum {BRT (disjunct)}, Ozothamnus kempei {BRT (eastern range limit) [E]}, Senecio laceratus {BRT (northern range limit) [N]}, Wahlenbergia caryophylloides {BRT (disjunct) [S] only known in BRT from this site} Other taxa only known in BRT bioregion from this site: Cheilanthes brownii, Euphorbia alsiniflora, Sida virgata, Solanum petrophilum, Triodia pungens var. linearis Botanically Significant Waterholes at the site: Dulcie Gorge Waterholes, Picton Springs Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 71 (9 %): Acacia aneura (Mulga) tall sparse-shrubland with grassland understorey. Map unit 43 (77 %): Eucalyptus low open-woodland and/or Acacia sparse-shrubland with Triodia spicata (Spike Flower Spinifex), Triodia pungens (Soft Spinifex) hummock grassland understorey. Map unit 58 (8 %): Acacia aneura (Mulga)/mixed species low open-woodland with open-grassland understorey. Map unit 59 (4 %): Acacia estrophiolata (Ironwood), Atalaya hemiglauca (Whitewood) low open-woodland with open-grassland understorey.
