Alice Mulga SuperSite​

TERN’s 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.

Site Research

Research using the Alice Mulga SuperSite aims to:
  • examine the daily, seasonal and inter-annual patterns of energy, carbon and water fluxes of Australian arid-zone Mulga and non-Acacia woodlands;
  • establish the responses and biological controls of energy, carbon and water fluxes to pulses of rain;
  • compare and contrast the behaviour of the soil, understorey and overstorey to pulses of rain by partitioning the fluxes between these three components of the ecosystem;
  • examine the impact of variation in soil moisture content (at multiple depths) and atmospheric vapour pressure deficit on the ecophysiology of the understorey and overstorey;
  • examine the influence of antecedent conditions on vegetation; and
  • examine the resilience of woody vegetation in relation to high interannual weather variation and extreme events including flood and drought.
