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.
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.
