This PhD will deliver fundamental research in support of managing saltmarshes, a coastal ecosystem with apurported, yet unqualified, role as a nursery habitat for UK fisheries species. Saltmarshes provide multipleecosystem services, including flood protection, blue carbon sequestration and water quality remediation (Hudson etal. 2021). They are central to Nature Based Solutions (NBS) of Shoreline Management Planning (SMP2),biodiversity conservation and emerging blue-carbon offsetting. Marshes are a priority habitat for restoration andconservation (25 Year Environment Plan, Defra) and integral to national biodiversity management (e.g., EnglandBiodiversity 2020 Strategy).Historically, British saltmarshes were depleted to < 1/4 of their cover, many through land-conversion for agriculture(Hudson et al. 2021). Restoring marshes is costly, involving significant engineering through 'managedrealignment', where defences are breached to convert terrestrial land into saltmarsh. Currently, the annual rate ofrestoration lags strongly behind the rate of losses (45 vs105 hectares/year) (Miles & Richardson 2018). The biggestbarrier to implementing restoration is insufficient data to enable otherwise powerful instruments such as NBS,Payment for Ecosystem services (PES) and National Habitat Compensation Programmes (Hudson et al. 2021). ThisPhD will incentivise these instruments through quantitative substantiation of the ecological benefits of marshrestoration and conservation to fisheries species.Several species that use marshes have high fisheries value (e.g., seabass, mullet, brown shrimp), but are threatened(eel) or their management is limited by data scarcity on nursery habitats (e.g., seabass, Defra 2021). Working withand at the Wildfowl & Wetland Trust (WWT), the student will couple environmental research to stakeholder andpolicy analyses, to identify barriers and solutions to boosting marsh management for fisheries species. The projectincludes contrasts between natural and restored sites to inform on restoration benefits to fisheries.

该博士将提供基本的研究，以支持管理盐玛希（Saltmarshes），这是一个沿海生态系统，具有备用但不合格的作用，是英国渔业物种的苗圃栖息地。 Saltmarshes提供多生殖系统服务，包括防洪，蓝色碳固存和水质修复（Hudson等，2021）。它们是海岸线管理计划（SMP2），生物多样性保护和新兴的蓝碳抵消的基于自然解决方案（NB）的核心。沼泽是恢复和保护的优先栖息地（25年环境计划，Defra），并且是国家生物多样性管理不可或缺的一部分（例如，Englandbiodoverity 2020策略）。从历史上看，英国的盐马什（British Saltmarshes）被耗尽至覆盖范围的<1/4，许多封面，许多通过土地转换的农业代表（Hudson Et et andssone）。恢复沼泽的成本很高，涉及通过“托管批准”的重要工程，在那里违反防御措施将陆地将其转换为盐玛什。目前，租赁的年率落后于损失率（45 vs105公顷/年）（Miles＆Richardson 2018）。实施恢复的最大攻击者是不足以实现其他功能强大的工具，例如NBS，生态系统服务（PES）和国家栖息地补偿计划（Hudson等，2021）。 ThisPhD will incentivise these instruments through quantitative substantiation of the ecological benefits of marshrestoration and conservation to fisheries species.Several species that use marshes have high fisheries value (e.g., seabass, mullet, brown shrimp), but are threatened(eel) or their management is limited by data scarcity on nursery habitats (e.g., seabass, Defra 2021).该学生将在Wildfowl＆Wetland Trust（WWT）上工作，将环境研究与利益相关者和政策分析息息相关，以确定障碍和解决方案，以增强渔业物种的沼泽管理。这些项目包括自然和恢复地点之间形成鲜明对比，以告知渔业的恢复益处。
