Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types could be used to better forecast the potential effects of climate change on forest ecosystems. This project also expects to identify heat-tolerant tree species and their relevant physiological traits, which can improve the success of urban tree plantings to help create cooler, greener cities throughout Australia.

热浪的频率和强度不断增加，极端高温对树木的生长和生存构成重大威胁。该项目旨在通过跟踪自然和实验热浪期间用水的动态变化（代表当前和未来的压力水平）来研究不同的澳大利亚树种如何应对极端高温。识别植物功能类型之间的可预测响应可用于更好地预测气候变化对森林生态系统的潜在影响。该项目还希望识别耐热树种及其相关生理特征，从而提高城市树木种植的成功率，帮助在澳大利亚各地创建更凉爽、更绿色的城市。
