(SGER) Cascading Consequences: Adaptive Management and the Science Behind Dam Decommissioning in Fossil Creek, Arizona

在国家科学基金会的资助下，将制作一部教育纪录片，利用即将修复的亚利桑那州化石溪，那里的一座大型水电站将于今年12月退役。纪录片《层叠后果》（Cascading Consequences）讲述了影响大型修复项目的复杂环境问题。这个项目的智力价值有四个组成部分。首先，这部纪录片将生态系统生态学与地质学结合起来，展示河流地貌的变化如何影响河流的分解和初级生产力。其次，视频将通过展示水电站大坝对河流生态系统的生态影响，记录先前水资源管理的生物学含义。第三，视频将展示纳入生态系统服务的渐进式水资源管理的后果。第四，该视频将强调包括人类在内的生物如何在食物网中相互联系，说明管理决策如何在食物网中产生涟漪。这项提议的更广泛影响有三个组成部分。首先，该视频将向公众电视观众介绍大坝拆除背后的科学依据，并将客观地讨论大坝安装和退役对水生生态系统的积极和消极影响。其次，该视频将为大学教授提供一个案例研究的场所，以说明如何将基础研究和研究工具（包括稳定同位素，分解实验，食物网研究和自然历史调查）应用于现实世界场景中的管理决策。第三，通过为高中教师提供配套的教育材料，该项目将接触到新一代学生，使他们成为生态系统恢复的领导者，打破科学家、决策者和资源管理者之间的障碍。

With NSF funding, an educational documentary will be produced, capitalizing on the upcoming restoration of Fossil Creek, Arizona where a large hydropower dam will be decommissioned this December. The documentary, Cascading Consequences, speaks to the complex environmental issues that inform large restoration projects. The intellectual merit of this project has four components. First, the documentary will integrate ecosystem ecology with geology by showing how changes in the fluvial geomorphology of the stream could affect decomposition and primary productivity. Second, the video will document the biological implications of prior water management by showing the ecological effects of the hydropower dam on stream ecosystems. Third, the video will show the consequences of progressive water resource management, incorporating ecosystem services. Fourth, the video will highlight how organisms, including humans, are interconnected in food webs, illustrating how management decisions ripple through food webs. The broader impacts of this proposal have three components. First, the video will inform the general public television audience about the scientific rationale behind dam removals, and will objectively discuss both the positive and negative consequences of dam installation and decommissioning to aquatic ecosystems. Second, the video will provide a venue for university professors to use a case study to illustrate how basic research and research tools including stable isotopes, decomposition experiments, food web studies, and natural history surveys can be applied to management decisions in a real world scenario. Third, by providing accompanying educational materials for high school teachers, this project will reach a new generation of students preparing them to be leaders in ecosystem restoration, breaking down barriers between scientists, policy makers, and resource managers.
