Many invasive species have strong negative impacts on biodiversity and ecosystem function and attempts to control or reverse their spread can be costly and require coordination among multiple institutions. This project integrates biological, mathematical, economic and political science tools to answer several critical and interrelated questions surrounding the invasive and high impact Eastern Smooth Cordgrass, Spartina spp, in San Francisco Bay. Two ways in which human intervention can mitigate the impact are to eradicate the invader and to restore the habitat. This is a complex problem with spatial linkages arising from the biology and impact of Spartina, and the spatial mosaic of governing agencies and responsible authorities. The project will focus on three questions: 1) What are the dynamics of eradication of an invasive species and subsequent restoration? 2) How can a program of eradication of an invasive species and subsequent restoration be designed taking into account both economics and ecology? 3) How do eradication and restoration policies depend on collective action on the part of multiple governmental and non-governmental stakeholders? This project will develop general models that will apply to a wide range of systems where an invasive species can have long lasting effects on the biotic and abiotic environment and to a much wider range of natural systems which are affected by humans and in which potential irreversibilities can occur. The eradication of invasive Spartina is one of the top priorities recently identified in the West Coast Governor's Agreement on Ocean Health, which provides a mandate for its eradication from the Pacific Coast by 2018. The project will provide specific guidance for control and restoration efforts in San Francisco Bay, and in other west coast estuaries, and will provide interdisciplinary research training for several graduate and undergraduate students and postdoctoral scholars. Outreach will provide information to the public about Spartina and invasive species more generally. The tools developed and lessons learned can be applied broadly to the wide range of ecosystem management projects with feedbacks between natural and human systems, including invasive species management, fisheries, endangered species protection, forest management, and the provision of ecosystem services more broadly.

许多入侵物种对生物多样性和生态系统功能都有强烈的负面影响，并且试图控制或扭转其传播的尝试可能是昂贵的，并且需要多个机构之间的协调。该项目将生物学，数学，经济和政治学工具整合在一起，以回答围绕旧金山湾的侵入性和高影响力东部光滑的山脉Spartina spp的几个关键和​​相互关联的问题。 人类干预可以减轻影响的两种方法是消除入侵者并恢复栖息地。 这是一个复杂的问题，它是由斯巴达那的生物学和影响以及管理机构和负责任机构的空间镶嵌物引起的空间联系。 该项目将重点放在三个问题上：1）根除入侵物种和随后的恢复的动态是什么？ 2）如何考虑经济学和生态学的根除计划和随后的修复计划？ 3）根除和恢复政策如何取决于多个政府和非政府利益相关者的集体行动？ 该项目将开发一般模型，这些模型将适用于广泛的系统，在这些系统中，入侵物种可能会对生物和非生物环境产生持久影响，以及受到人类影响并可能发生潜在的不可逆转的自然系统范围更广泛的自然系统。 根除侵入性斯巴达氏菌是西海岸州长的海洋健康协议最近确定的最重点之一，该协议在2018年到2018年从太平洋海岸消除了其授权。该项目将为旧金山湾的控制和恢复工作提供具体的指导，以在西海岸的其他研究中，以及在其他西海岸的研究中为跨学科的研究培训提供了一些培训和下一个毕业生和下一个培训。 外展将向公众提供有关斯巴达纳和入侵物种的信息。 开发的工具和经验教训可以广泛地应用于自然系统和人类系统之间的反馈，包括入侵物种管理，渔业，濒危物种保护，森林管理以及提供生态系统服务。
