Summary: The aim of this project is to determine the response of trees to extraction of shallow groundwater. This is important because excessive depletion of groundwater resources has a negative impact on groundwater dependent ecosystems (GDEs), which rely on a supply of groundwater to maintain ecosystem health, structure and function. The results of this study will inform industry regulators and the water supply industry on how to improve management of both groundwater and vegetation resources. This proposal is innovative because it will combine a field-scale experimental depletion of groundwater resources simultaneously with alterations in rainfall input and measurements of tree responses.
