Volume 2, Part 2, page 271 Tanami 11. Tanami Bioregion 11.1 OVERVIEW OF THE NT PORTION OF THE TANAMI BIOREGION The Tanami bioregion comprises an area of 298,100km2, 91% (271,200km2) of which is located in the Northern Territory. The Tanami bioregion extends into Western Australia (figure 2). The NT portion of the bioregion is dominated by the vast Quaternary sandplains of the Tanami Desert. The sandplains, largely comprised of hard-setting earthy sands with gravelly mantles of ironstone, are punctuated by low laterite capped mesas, silcrete covered hills and rises, and narrow mounds of calcrete on the margins of drainage depressions. Other features include low ranges or hills composed of Permian and Proterozoic sandstones such as the Gardiner and Pargee Ranges and the uplands north of Tennant Creek. The bioregion has a tropical semi-arid climate. The climate is dry with highly variable rainfall which mostly falls in the summer months in association with monsoonal troughs. The bioregion is not subjected to winter frosts. The characteristic vegetation on sand plains in the bioregion is dominated by Hakea, Acacia, Corymbia and Grevillea spp. over Triodia pungens and Triodia schinzii hummock grasslands. Significant areas of halophytic vegetation occur around salt lakes and within paleodrainage systems. A total of 288 indigenous vascular plant taxa are currently considered to of conservation significance in the NT portion of the Tanami bioregion. These taxa are listed in volume 1, appendix 3.
