Location and description
The region consists of sandy plains with some areas of rocky highland. These plains have a dry climate but do get some rain in both summer and winter. This area contains the remote city of Alice Springs while the grasslands are home to a number of Indigenous Australian communities or are used for cattle grazing.
This ecoregion contains four Interim Biogeographic Regionalisation for Australia (IBRA) bioregions – Burt Plain, Central Ranges, Finke, and MacDonnell Ranges.
Flora
This ecoregion includes the Central Australian Mountain Ranges Centre of Plant Diversity. The habitats consists of thick, tough spinifex grassland with some wooded areas of myall and desert oak (Acacia coriacea). The region and the MacDonnell Ranges in particular are home to a number of specialised endemic plant species including the cabbage palms of Palm Valley in Finke Gorge National Park.

Protected areas
Protected areas include Finke Gorge National Park, Watarrka National Park, and West MacDonnell National Park.
