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韦尔弗利特和特鲁罗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项目。这项拟议的研究将是涉及许多组织的多学科监测项目的一部分。通过在河口处重建堤坝和潮汐控制结构，逐步开放，使潮汐流重新流入河流，最终将使正常潮差和盐度恢复到约445公顷，从而恢复河口进程，改善河口动植物的生境。潮汐流的恢复将由国家公园管理局制定的正式适应性管理计划指导和通知。河口的颗粒物和营养盐通量知之甚少。沉积物，营养盐，颗粒有机物的来源，以及整个鲱鱼河口的分布是未知的。这项研究将通过生物测定和稳定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。调查鲱鱼河口恢复前、中、后条件的独特机会将是规划、实施和管理沿海生境未来恢复工作的基础。
