Made available via the Publications (Legal Deposit) Act 2004 (NT).; This report provides a benchmark for the conservation status of botanical values in the southern, predominantly arid part of the Northern Territory. It will have many and varied uses, providing information about conservation values to land holders and managers as well as government departments and conservation groups.

Volume 2, Part 2, page 152 Great Sandy Desert Site: 23-2-6 Lay Cock's Sandplain Level of significance: bioregional Location: 23 52' S 131 14' E; ca. 60 km north west of Watarrka. Area: 1854 km2 Map sheets: Mount Liebig SF 52-16 & Lake Amadeus SG 52-4 Bioregions: Great Sandy Desert (GSD 93.7%) & MacDonnell Ranges (MAC 6.3%) Tenure: Freehold - Haasts Bluff Aboriginal Land Trust (100% of site) Description: This site comprises an area of sandplain fringed by low ranges. The sand sheet in places is thin and habitats for plants maybe strongly influenced by the hydrological characteristics of the underlying sandstone. The site is bounded in the west by a low rise or scarp associated with an exposure of Cleland sandstone known as the Watson Range. To the east the site is bounded by but also includes an extensive but partially sand covered exposure of Mereenie sandstone - a geology strongly correlated with the occurrence of rare plants due its capacity to hold water. This range is known as the Glen Edith Hills. Notes: This is an important and currently poorly known region on the western fringe of the Macdonnell Ranges bioregion. The site includes a number of important sandstone outcrops which support rare plants and potentially rare plant communities. Of particular note is the Tarn of Auber, a rocky knoll comprised of Mereenie sandstone, which is well known for the presence of rare plant populations. It is one of the few areas within the site to have been visited by botanical collectors. Botanical values are not uniform across the site and boundaries have been extrapolated employing physiographic and geological boundaries. The site includes the type locality for Logania centralis. Criteria satisfied: A1 a ii), A1 b ii), B1 b1 ii) Taxa of Australian significance: Comesperma viscidulum {3KC-}, Daviesia arthropoda {3KCa}, Euphorbia sarcostemmoides {3KCa}, Logania centralis {3KC- only known in GSD from this site}, Sauropus ramosissimus {3KC-} Taxa of NT significance: Acacia helmsiana {3k [E]}, Calotis cuneifolia {3k only known in GSD from this site}, Commicarpus australis {3r only known in MAC from this site}, Dodonaea microzyga var. microzyga {3r}, Dysphania sphaerosperma {3r}, Eragrostis A51007 Limestone {3k [W]}, Eragrostis sterilis {3rC-}, Glischrocaryon aureum var. angustifolium {3rC-}, Gompholobium simplicifolium {3r only known in GSD from this site}, Goodenia glandulosa {3rC- only known in GSD from this site}, Grevillea pterosperma {3r only known in GSD from this site}, Kippistia suaedifolia {3r only known in GSD from this site}, Laxmannia arida {3r}, Newcastelia bracteosa {3k only known in GSD from this site}, Ophioglossum lusitanicum {3rC-}, Sclerolaena parviflora {3r}, Sida A83689 Golden calyces {3kC-}, Stenanthemum A81040 Docker River {3k}, Xanthorrhoea thorntonii {3rCa only known in GSD from this site} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Aristida arida {MAC (western range limit) [W]}, Eucalyptus gongylocarpa {GSD (northern range limit) [N]}, Haloragis odontocarpa forma octoforma {MAC (apparently rare) only known in NT from this site}, Lechenaultia striata {GSD (northern range limit) [N]}, Polycarpaea involucrata {GSD (disjunct)}, Prostanthera althoferi subsp. longifolia {GSD (northern range limit) [N] only known in GSD from this site}, Ptychosema anomalum {GSD (northern range limit) [N]} Other taxa only known in GSD bioregion (NT portion) from this site: Acacia bivenosa, Chenopodium truncatum, Dodonaea lanceolata var. lanceolata, Glossocardia bidens, Ptilotus parvifolius var. parvifolius, Solanum esuriale Type locations of the following were collected from the site: Logania centralis (1984) Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 93 (90 %): Triodia basedowii (Hard Spinifex) hummock grassland with Allocasuarina decaisneana (Desert Oak) openwoodland overstorey between dunes. Map unit 30 (3 %): Eucalyptus gongylocarpa (Marble Gum) open-woodland with open-hummock grassland understorey. Map unit 73 (3 %): Acacia tetragonophylla (Dead Finish), Acacia kempeana (Witchetty Bush) sparse-shrubland with herb/grassland understorey. Map unit 92 (1 %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey.
