Volume 2, Part 2, page 110 Finke 5.2 SITES OF NATIONAL SIGNIFICANCE IN THE NT PORTION OF THE FINKE BIOREGION Site: 24-3-2 Wolluga Dunefields Level of significance: national Location: 24 41' S 132 17' E; Northern Henbury-Erldunda Plains Area: 758 km2 Map sheet: Henbury SG 53-1 Bioregions: Finke (FIN 69.8%) & Great Sandy Desert (GSD 23.8%) & MacDonnell Ranges (MAC 6.4%) Tenure: Pastoral Lease - Angus Downs Station (79% of site); Freehold - Urrampinyi Iltjiltjarri Aboriginal Land Trust (20% of site), Ukaka Aboriginal Corp. (<1% of site) Description: This large site is bounded in the north by the northern fall of the Levi Range and to the south by a series of low gypseus rises and associated claypans. The intervening dunefield is occasionally interrupted by minor outcroppings of Mereenie sandstone and gypsum. Notes: The site is notable for the presence of a large population of Microcorys macrediana. This is the only known population of this species in the Northern Territory. The occasional exposures of Mereenie sandstone probably indicate that the sandsheet covering this area is quite shallow. This may go some way towards explaining the concentration of rare or otherwise significant plant taxa in this area. The site also includes the type localities of Eucalyptus mannensis, Chenopodium truncatum and Wurmbea deserticola. Criteria satisfied: B1 b1 i) Taxa of Australian significance: Daviesia arthropoda {3KCa}, Harnieria kempeana subsp. kempeana {3RC- [S]}, Microcorys macrediana {3K [NE] only known in NT from this site} Taxa of NT significance: Acacia nyssophylla {3k [N]}, Amyema miraculosa subsp. boormanii {3k}, Austrostipa trichophylla {3rC- only known in MAC from this site}, Bulbine alata {3k only known in MAC from this site}, Calotis cymbacantha {3kC-}, Chthonocephalus pseudevax {3r}, Cuphonotus andraeanus {3r only known in GSD from this site}, Dodonaea microzyga var. microzyga {3r only known in GSD from this site}, Dysphania sphaerosperma {3r}, Eragrostis A51007 Limestone {3k}, Eremophila alternifolia {3k}, Eriochiton sclerolaenoides {3k}, Goodenia havilandii {3rC- only known in GSD from this site}, Goodenia occidentalis {3rC-}, Ixiolaena tomentosa {3kC- only known in FIN from this site}, Minuria multiseta {3r}, Newcastelia bracteosa {3k}, Osteocarpum salsuginosum {3r}, Pomax A89438 Sand Dunes {3kC-}, Poranthera microphylla s.lat. {3rC-}, Sclerolaena parviflora {3r}, Swainsona laxa {3r only known in GSD from this site} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Acacia abrupta {MAC (eastern range limit) [E]}, Brachychiton gregorii {FIN (apparently rare)}, Eremophila D41598 MacDonnell Ranges {GSD (southern range limit) [S]}, Eremophila paisleyi {GSD (apparently rare)}, Lechenaultia striata {FIN (apparently rare and eastern range limit) [E]} Other taxa only known in FIN bioregion (NT portion) from this site: Calytrix carinata, Cyperus dactylotes, Goodenia mueckeana, Haloragis odontocarpa forma rugosa Other taxa only known in MAC bioregion from this site: Brachycome iberidifolia; Other taxa only known in GSD bioregion (NT portion) from this site: Goodenia berardiana, Nicotiana simulans Type locations of the following were collected from the site: Chenopodium truncatum (1968), Eucalyptus mannensis (1957), Wurmbea deserticola (1956) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 92 (1 < %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey.
