Unprecedented levels of keystone Banksia species mortality and an increased number of species with reduced capacity to provide vital ecosystem services is leading to ecosystem change and reduced resilience of Western Australian woodlands. In water sensitive ecosystems, failure to capture and integrate above- (tree function and ecology) and below-ground (soil hydrology and physics) processes at various scales (individual to landscape) has seen global tree decline remain unresolved. Using this approach, the project aims to identify processes leading to, and identify areas at high risk of, significant ecosystem change. Outcomes are expected to include the establishment a benchmark approach in understanding global ecosystem change to inform land management in a changing climate.

Keystone Banksia物种死亡率达到史无前例的水平，提供重要生态系统服务的能力下降的物种数量增加，导致生态系统变化和西澳大利亚林地弹性降低。在对水敏感的生态系统中，未能捕捉和整合不同尺度(从个体到景观)的地上(树木功能和生态)和地下(土壤水文和物理)过程，导致全球树木衰退问题仍未解决。使用这种方法，该项目旨在确定导致重大生态系统变化的过程，并确定具有重大生态系统变化风险的地区。预期成果将包括建立一个了解全球生态系统变化的基准方法，以便在气候变化时为土地管理提供信息。
