The Pacific Northwest is experiencing increased drought and wildfire, and decreased snow packs. There is much uncertainty about how its ecosystems of forests, streams, and mountain meadows will respond. Ecologically, these habitats are experiencing environmental changes in very different ways. Socially, public values associated with these areas vary greatly and can be in conflict with one another. The goal of this long-term project is to understand how and why forested mountain ecosystems respond to changes in climate, land-use decisions, and the relationship between climate and land-use decisions. Over the next six years, research will focus on determining how physical and biological processes interact to alter ecosystem and species responses to changing climate in mountain ecosystems. Simultaneously, researchers will examine how forest managers combine science and values to make decisions that affect these ecosystems. Working with non-scientists in the arts and humanities, researchers will enhance public literacy about science, demonstrate the value of long-term ecological research, and convey the strong sense of place necessary to improve the well-being of all stakeholders. The project will continue education and outreach activities for teachers and K-12, undergraduate, and graduate students. Additionally, scientists will continue to engage the general public, with an emphasis on enhancing participation of women, people with disabilities, and those from under-represented backgrounds.The project addresses the question: How do climate, natural disturbance, and land use -- as influenced by values and decisions -- interact with biodiversity, hydrology, and carbon and nutrient dynamics? Research will employ the ecological concept of “interactions” to evaluate and characterize spatial and temporal patterns and processes in old-growth temperate forests, streams, and montane meadows of the HJ Andrews Experimental Forest in Oregon. Analyses of long-term climate data will be used to investigate how forests modulate the expression of regional climate to create local microclimates. More specifically, analysis of temperature, snow, and vegetation data will be combined with short-term studies of tree physiology, canopy microbiomes, and remote sensing of forest ecosystems to examine how microclimate and legacies of land use and disturbance influence populations, communities and ecosystem processes. Analyses of long-term bird, fish, and vegetation data and integrated, multi-taxa experiments on birds, lichens, trees, fish, and salamanders will examine how species interactions amplify or reduce responses to microclimate. New studies of conservation ethics and the effects of long-term ecological science on management will explore how values filter the use of science in land-use decisions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

西北太平洋正在经历增加干旱和野火，并增加了雪包。关于其森林，溪流和山地草地的生态系统如何做出反应，存在很多不确定性。从生态上讲，这些栖息地以非常不同的方式经历环境变化。在社会上，与这些领域相关的公共价值观差异很大，并且可能相互冲突。这个长期项目的目的是了解如何以及为什么森林山区生态系统应对气候变化，土地利用决策以及气候和土地利用决策之间的关系。在接下来的六年中，研究将集中于确定物理和生物学过程如何相互作用，以改变生态系统和物种对山地生态系统中气候变化的反应。同时，研究人员将研究森林经理如何结合科学和价值观以做出影响这些生态系统的决策。研究人员与非科学主义者在艺术和人文方面合作，将增强有关科学的公众素养，展示长期生态研究的价值，并传达提高所有利益相关者福祉所必需的强烈地位感。该项目将继续为教师和K-12，本科生和研究生的教育和外展活动。此外，科学家将继续与公众参与，重点是增强妇女，残疾人和代表性不足的背景的参与。该项目解决了以下问题：气候，自然灾害和土地利用如何受到价值观和决策的影响 - 与生物生物企业，水力学，水文和碳和碳和营养动力学相互作用？研究将采用“相互作用”的生态概念来评估和表征俄勒冈州HJ Andrews实验森林的旧温度森林，溪流和山地草地中的空间和临时模式和过程。长期气候数据的分析将用于研究森林如何调节区域气候的表达以创建局部微气候。更具体地说，对温度，积雪和植被数据的分析将与森林生态系统的树层生理学，冠层微生物组和遥远敏感性的短期研究相结合，以研究土地使用和灾难的微气候和遗产如何影响人群，社区和生态系统过程。对长期鸟类，鱼​​类和植被数据的分析以及对鸟类，地衣，树木，鱼类和sal的综合，多核心实验将研究物种相互作用如何放大或减少对微气候的反应。关于保护伦理学和长期生态科学对管理的影响的新研究将探讨价值如何过滤科学在土地利用决策中的使用。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估来获得支持的。
