The Big Desert (Environmental Association 2.3.3)

location map showing The Big Desert (Environmental Association 2.3.3)

An undulating plain on calcrete with a cover of aeolian sand sheet and dunes. Although the natural vegetation of mallee and heath has been disturbed by fire, very little has been cleared for grazing, and the area is mainly in conservation areas of remains as vacant crown land.

Foreground perspective and enclosed views can be obtained from low in the landscape, whilst middleground and background panoramas can be viewed from the higher dunes.
