The Herring River Habitat Restoration Project in Wellfleet and Truro, MA, USA will be the largest estuarine habitat restoration in the north-eastern USA. The proposed study will be part of a multidisciplinary monitoring project involving numerous organisations. Reintroduction of the tidal flow to the river by means of incremental openings of a rebuilt dike and tidal control structure at the mouth of the river will eventually restore normal tidal range and salinity to approximately 445 hectares, allowing for reestablishment of estuarine processes and improved habitat for a host of estuarine plants and animals. Restoration of tidal flow will be guided and informed by a formal Adaptive Management Plan developed by the National Park Service. Fluxes of particulates and nutrients in estuaries are poorly understood. Sources of sediments, nutrients, particulate organic matter, as well as distribution throughout Herring River estuary are unknown. This study will answer those questions with bioassay and stable isotope studies and will be part of a comprehensive monitoring project. The unique opportunity of surveying pre-, mid- and post- restoration conditions of the Herring River Estuary will be fundamental for planning, implementing and managing future restoration efforts of coastal habitats.

位于美国马萨诸塞州Wellfleet和Truro的鲱鱼河栖息地恢复项目将是美国东北部最大的河口栖息地恢复。拟议的研究将是涉及众多组织的多学科监测项目的一部分。通过重建的堤防和河口口的重建堤防和潮汐控制结构的增量开口重新引入潮汐流，最终将使正常的潮汐范围和盐度恢复到大约445公顷的位置，从而可以重新建立河口过程，并改善雌雄河植物和动物的宿主。由国家公园管理局（National Park Service）制定的正式自适应管理计划指导和告知潮流的恢复。河口中的颗粒和养分的通量知之甚少。沉积物，养分，颗粒有机物以及整个鲱鱼河河口的分布的来源尚不清楚。这项研究将通过生物测定和稳定的同位素研究回答这些问题，并将成为全面监测项目的一部分。对鲱鱼河口前，中期和后恢复状况进行调查的独特机会将是计划，实施和管理沿海栖息地的未来恢复工作的基础。
