Site description: The Mitchell Grass Rangeland site has been established near Longreach in Western Queensland. Mitchell Grass Rangeland is a TERN SuperSite managed by the Queensland University of Technology. The site is located on an actively grazed cattle and sheep property recently affiliated with the Longreach Pastoral College, the Queensland Department of Primary Industries Rosebank Research Station and several CSIRO research programs. Mitchell Grass Rangelands are defined by mostly treeless plains with occasional ridges, rivers and gorges. Curly Mitchell Grass (Astrebla lappacea), Bull Mitchell Grass (Astrebla squarrosa) and Hoop Mitchell Grass (Astrebla elymoides) are the dominant vegetation in the area. A low overstorey of Gidgee (Acacia cambagei) and other tree and shrub species may be found in some places.

The site’s two dry acoustic sensors are located on open grassy plains dominated by Mitchell Grass tussocks. The site’s two wet acoustic sensors are located along creek and drainage lines fringed with Coolabah (Eucalyptus coolabah) and River Red Gum (Eucalyptus camaldulensis).
