As the world's second largest terrestrial biome, the boreal forest plays a crucial role in the global water cycle. The goal of this project is to quantify and understand biological atmospheric losses of water from boreal forests recovering from natural wildfire disturbances. Biological control occurs because plants regulate the amount of water lost while photosynthesizing. Current models of evaporated water into the atmosphere from boreal forests are to simplistic because of a lack of data separating water lost from trees versus mosses, of which the former has markedly different controls than the latter over water loss. This project will enable the scientific and land management communities to assess how much complexity is required to adequately predict water losses from boreal forests that are experiencing and may continue to experience increased wildfire frequency. The project will serve as an ideal training ground for future scientists and land managers who work on systems that may modify the vegetation and thus water cycle by training post-docs, graduate and undergraduate students. The project will continue current efforts by the project leaders to integrate science and education through ties with local native peoples, high schools and community colleges.

作为世界上第二大陆地生物群落，北方森林在全球水循环中发挥着至关重要的作用。该项目的目标是量化和了解从自然野火干扰中恢复的北方森林的水的生物大气损失。生物控制的发生是因为植物调节光合作用时失去的水量。目前的模式蒸发的水进入大气中的北方森林是简单化，因为缺乏数据区分水分损失的树木和苔藓，其中前者有显着不同的控制比后者的水分损失。该项目将使科学界和土地管理界能够评估需要多大的复杂性才能充分预测正在经历并可能继续经历野火频率增加的北方森林的水损失。该项目将成为未来科学家和土地管理人员的理想培训基地，他们通过培训博士后、研究生和本科生，研究可能改变植被从而改变水循环的系统。该项目将继续项目领导人目前的努力，通过与当地土著人民、高中和社区学院的联系，将科学和教育结合起来。
