Volume 2, Part 2, page 104 Davenport Murchison Ranges Site: 21-5-2 Upper Elkedra River Level of significance: bioregional Location: 21 5' S 135 21' E; Southern Davenport Ranges Area: 273 km2 Map sheet: Elkedra SF 52-7 Bioregion: Davenport Murchison Ranges (DAV) Tenure: Pastoral Lease - Elkedra Station (100% of site) Description: This site includes the valley and fringing ridges of the upper Elkedra River. The site includes permanent and semipermanent waterholes along the Elkedra River from Erlpunda waterhole in the east to Turkey Camp Yard in the west. The geology is primarily recent alluvium in the valley and quartz sandstone on the surrounding hills. The botanical values tend to be concentrated on the floor of the valley and permanent waterholes. Notes: The site is the type locality for Zornia albiflora. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: Cullen walkingtonii {3KC-}, Heliotropium subreniforme {3K only known in DAV from this site} Taxa of NT significance: Centipeda A92472 Toko Range {3kC- only known in DAV from this site}, Eleocharis setifolia {3r only known in study area from this site}, Fuirena nudiflora {3k only known in DAV from this site}, Juncus aridicola {3rC- only known in DAV from this site}, Ophioglossum gramineum {3r only known in NT from this site}, Triumfetta centralis {3k only known in DAV from this site}, Yakirra muelleri {3k} Taxa of Southern NT (study area) significance: Acacia hemsleyi {(disjunct) [S]}, Centipeda minima subsp. A59802 Elkedra {(apparently disjunct & apparently rare) only known in study area from this site}, Crotalaria novae-hollandiae subsp. novaehollandiae {(disjunct) only known in DAV from this site}, Fimbristylis nuda {(disjunct & apparently rare)}, Microcarpaea minima {(disjunct & rare)}, Mitrasacme micrantha {(disjunct) [S]}, Panicum mindanaense {(disjunct)}, Vallisneria annua {(disjunct)} Taxa of bioregional significance: Blumea diffusa {DAV (disjunct) only known in DAV from this site}, Chenopodium melanocarpum {DAV (northern range limit) [N] only known in DAV from this site}, Chenopodium truncatum {DAV (northern range limit) [N] only known in DAV from this site}, Crotalaria brevis {DAV (disjunct) only known in DAV from this site}, Eriachne melicacea {DAV (southern range limit) [S]}, Gomphrena cunninghamii {DAV (disjunct)}, Goodenia larapinta {DAV (eastern range limit) [E] only known in DAV from this site}, Iphigenia indica {DAV (disjunct)} Other taxa only known in DAV bioregion from this site: Calotis plumulifera, Eragrostis desertorum, Eragrostis parviflora, Euphorbia petala, Heliotropium pachyphyllum, Melhania oblongifolia, Phyllanthus fuernrohrii, Rhodanthe tietkensii, Sorghum plumosum var. plumosum, Stackhousia intermedia Type locations of the following were collected from the site: Zornia albiflora (1956) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 43 (75 %): Eucalyptus low open-woodland and/or Acacia sparse-shrubland with Triodia spicata (Spike Flower Spinifex), Triodia pungens (Soft Spinifex) hummock grassland understorey. Map unit 27 (24 %): Eucalyptus microtheca s. lat. (Coolibah) low open-woodland with open-grassland understorey.
