Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which water transport breaks down in roots, stems and leaves and the mechanisms governing recovery from severe drought stress. The project will provide a deeper understanding of drought tolerance in trees, improved forecasting of risks to native vegetation, and enhanced management of native forest resources.

预计在不久的将来，干旱将变得更加极端，对澳大利亚的森林生态系统造成潜在的破坏性影响。该项目旨在解决我们对植物如何耐受极端干旱胁迫的理解中的关键知识差距，并利用这些新知识来改进适合评估生态系统脆弱性的植被模型。我们将使用创新的实验方法，以确定水运输打破了根，茎和叶的过程和严重干旱胁迫的恢复机制。该项目将使人们更深入地了解树木的耐旱性，改进对原生植被风险的预测，并加强对原生森林资源的管理。
