The Alice Mulga SuperSite is a part of the Australian Terrestrial Ecosystem Network (TERN, http://www.tern.org), which provides environmental research infrastructure for understanding how and why ecosystem change occurs (https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/). The Alice Mulga SuperSite is located on Pine Hill Cattle Station approximately 200 km north of Alice Springs, Northern Territory. It lies in the expansive arid and semi-arid portion of mainland Australia that receives less than 500 mm of annual rainfall. The site includes Mulga woodland, hummock grassland, and river red gum forest. The SuperSite Core 1 ha is located in a dense Mulga woodland (cover 70–80%). The SuperSite has a second TERN OzFlux tower at Ti Tree East where TERN Surveillance Plots are also located in a mosaic of hummock grassland/Corymbia savanna with patches of Mulga/tussock grass. A third study location in the SuperSite is a river red gum forest along the Woodforde river where where several hydrological and plant ecophysiological studies have been performed. The traditional owners of these lands are the Anmatyerre Nation.
