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 93 Davenport Murchison Ranges 4. Davenport Murchison Ranges Bioregion 4.1 OVERVIEW OF THE DAVENPORT MURCHISON RANGES BIOREGION/SUBREGION The Davenport Murchison Ranges bioregion/sub-region comprises an area of 15,900km2, all of which is located in the Northern Territory. This bioregion is defined by the uplands comprising the Davenport and Murchison Ranges and their associated run-on and flood-out areas. These flat-topped sandstone ranges are dissected by steep valleys, many of which contain permanent or semi-permanent waterholes. The ranges give rise to a number of major rivers and watercourses including the Elkedra and Frew Rivers. These watercourses support in-stream waterholes. The region is topographically and floristically distinct from the surrounding Tanami bioregion. Readers are reminded here that the Davenport Murchison Ranges bioregion is not part of the 1995 national bioregionalisation (Thackway and Cresswell, 1995), which recognised it as part of the vast Tanami bioregion. The principal soils of the ranges are shallow lithosols. Deep fine grained alluvial soils are found in the valleys and surrounding plains. The vegetation is dominated by hummock grasslands (Triodia spp) with a sparse over story of trees and shrubs. It is also an important region for aquatic and semi-aquatic vegetation because of the large number of permanent or semi-permanent waterholes. The climate is arid-tropical with most rainfall falling in the summer months in association with monsoonal low pressure systems. There are 84 significant botanical taxa recognised from the Davenport and Murchison Ranges bioregion. These taxa are listed in volume 1, appendix 3.
