The national benefit of this project is significant. Woodlands and forests transpire vast amounts of water into the atmosphere and this water is thus lost to human consumptive use. Given large variation in rainfall between years and between seasons, it is vital that water and catchment resource managers are able to estimate how much water is lost through trees. This allows estimation of the amount of water available for irrigation, drinking, other industrial uses or maintaining ecosystem health. This project will be the first to generate a mechanistic understanding thereby allowing estimates of water use across a range of woody ecosystems in Australia.

该项目的国家效益是显著的。林地和森林向大气中蒸发了大量的水，这些水因此被人类消耗。由于不同年份和不同季节的降雨量变化很大，水和集水资源管理人员必须能够估计有多少水通过树木流失。这就可以估计可用于灌溉、饮用、其他工业用途或维持生态系统健康的水量。该项目将是第一个产生机械的理解，从而允许在澳大利亚的一系列木本生态系统的用水量的估计。
