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.

作为世界第二大陆地生物群落，北方森林在全球水周期中起着至关重要的作用。该项目的目的是量化和理解从天然野火障碍中恢复的北方森林中水的生物大气损失。生物控制之所以发生，是因为植物调节光合作用时损失的水量。由于缺乏从树木与苔藓与苔藓相比的数据分离的数据，目前从北方森林中蒸发水进入大气的模型非常简单，而后者的控制与后者在水损失方面的控制明显不同。该项目将使科学和土地管理社区能够评估需要多少复杂性，以充分预测正在经历的北方森林中的水分流失，并可能会继续经历增加的野火频率。该项目将成为未来的科学家和土地管理人员的理想培训场所，这些科学家和土地管理人员可以通过培训后，毕业生和本科生来修改植被，从而通过培训进行水周期。该项目将继续由项目负责人当前的努力，通过与当地的原住民，高中和社区学院的联系来整合科学和教育。
