Eucalyptus wandoo forests and woodlands once covered a large area in SW Western Australia. Remnants of these ecosystems are now threatened by the Wandoo Crown Decline syndrome. We hypothesise that the progressive dieback of branches is due to drought stress, causing irreversible damage to water supply and/or predisposing trees to fungal disease. The project aims at identifying the physiological mechanism of Wandoo Crown Decline. This knowledge is imperative for the assessment of risks for wandoo populations and for the formulation of management options.

桉树林和林地曾经覆盖了澳大利亚西南部的大片地区。这些生态系统的残余现在受到旺杜冠衰综合征的威胁。我们假设，进行性枯死的分支是由于干旱胁迫，造成不可逆转的损害供水和/或诱发树木真菌病。该项目旨在确定旺都树冠衰退的生理机制。这方面的知识对于评估旺杜人的风险和制定管理方案至关重要。
