(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，利用亚利桑那州化石溪即将进行的恢复工作，那里的一个大型水电站大坝将于今年12月退役。 这部名为《级联后果》的纪录片讲述了为大型修复项目提供信息的复杂环境问题。 这个项目的智力价值有四个组成部分。 首先，该纪录片将通过展示河流地貌的变化如何影响分解和初级生产力，将生态系统生态学与地质学相结合。第二，视频将通过展示水电站大坝对河流生态系统的生态影响，记录先前水管理的生物影响。第三，视频将展示逐步水资源管理的后果，包括生态系统服务。第四，视频将突出包括人类在内的生物体如何在食物网中相互联系，说明管理决策如何在食物网中涟漪。 这一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原理，并客观地讨论大坝安装和拆除对水生生态系统的积极和消极影响。其次，视频将为大学教授提供一个场所，使用案例研究来说明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，可以应用于管理决策在真实的世界场景。第三，通过为高中教师提供配套教育材料，该项目将影响新一代学生，使他们成为生态系统恢复的领导者，打破科学家，政策制定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.
