Volume 2, Part 2, page 221 Mitchell Grass Downs 8. Mitchell Grass Downs Bioregion 8.1 OVERVIEW OF THE NT PORTION OF THE MITCHELL GRASS DOWNS BIOREGION The Mitchell Grass Downs bioregion comprises an area of 307,900km2, 28% (84,900km2) of which is located in the Northern Territory. The remainder of this bioregion is located in Queensland. This region is characterised by flat gently undulating treeless plains with occasional shallow (seasonally wet) lake basins. The soils of the NT portion of the bioregion are typically deep grey clays, commonly referred to as black soil plains. The vegetation of the Mitchell Grass Downs is predominantly Astrebla spp. dominated tussock grasslands but extensive areas of Gidyea (Acacia georginae) woodlands occur in the south east of the region. Wetlands and seasonal swamps support Bluebush (Chenopodium auricomum) shrublands. The climate is semi-arid tropical. Rainfall is strongly seasonal falling in the summer months in association with monsoon troughs. A total of 93 indigenous vascular plant taxa are currently considered to be of conservation significance in the NT portion of the Mitchell Grass Downs bioregion. These taxa are listed in volume 1, appendix 3. This bioregion is poorly known botanically and it is expected that a considerable number of apparently rare plant taxa are an artefact of under-collection and a general lack of botanical survey.
