Manipulating forest density and structure to maximize snow retention in maritime mountain basins

这项研究将考察森林结构和气候变化对积雪和径流的作用。这项研究将把实地测量与建模工作结合起来，以量化森林结构和气候变化的相对重要性。将讨论三个主要问题：(1)不同森林结构和类别中积雪截留和融化的可变性是什么？(2)在几十年的时间里，哪些森林变化对雪水储存的影响可以与气候变化相媲美？哪些森林变化加剧了较早的径流，哪些景观上的雪保留得更长？(3)如何在流域管理中使用营林做法来帮助抵消预计的气候变化的影响？为本研究提出的森林-雪相互作用的精细空间分析预计将导致改进流域的水文模拟，其中包括海洋山脉盆地的间歇性雪区等。开发的模型将用于课堂教育和管理场景。教育介绍和实地考察将涉及当地社区和来自Mucklushot印第安人部落社区学院的学生。

The research will combine field measurements with modeling efforts to quantify the relative importance of forest structure and climate change. Three major questions will be addressed: (1) What is the variability of snow interception and melt in different forest structures and classes? (2) Over multiple decades, which forest changes are of comparable magnitude to climate change in their effects on snow water storage? Which forest changes exacerbate earlier runoff, and which retain snow longer on the landscape? (3) How can silvicultural practices be used in watershed management to help offset the effects of projected climate change? The fine-scale spatial analysis of forest-snow interactions proposed for this study are anticipated to lead to improved hydrologic modeling of watersheds that include the intermittent snow zone of maritime mountain basins, among others. The model developed will be used in classroom education and management scenarios. Educational presentations and field trips will involve the local community and students from the Muckleshoot Indian Tribal Community College.
