The development of science-based restoration goals that reflect the primary motivation of stakeholders is a key factor leading to large-scale, long-term restoration successes. The ability to predict the potential ecosystem service delivery from restoration can inform the setting of appropriate goals and facilitate the strategic planning of restoration activities. While recovery of the ecosystem services provided by oyster reefs is a regularly cited reason for undertaking restoration, few examples exist where large-scale oyster habitat restoration plans have been informed using ecosystem service functions. Such an approach is currently being implemented in the Pensacola Bay System, Florida, where a broad coalition of partners and community stakeholders are utilizing a watershed approach to restoring oysters with the aim of restoring oysters for multiple objectives including habitat, ecosystem services, and wild harvest and aquaculture. Through the process of developing a habitat management plan, water filtration was identified as a key ecosystem service by the stakeholders. To support restoration planning we derived a spatially explicit estimate of water filtration services provided by the eastern oyster in the Pensacola Bay system by linking an oyster habitat suitability map to a hydrodynamic-oyster filtration model. This spatially explicit model allowed us to identify the areas where restored oyster reefs have the potential to provide the greatest increase in filtration service as well as provide spatially explicit estimates of the potential filtration provided by oyster habitat restored. Such information is useful in restoration planning and management and for stakeholder engagement, outreach, and education programs.
制定基于科学的恢复目标以反映利益相关者的主要动机，是实现大规模、长期恢复成功的关键因素。预测恢复措施可能带来的生态系统服务功能，有助于设定恰当的目标，并推动恢复活动的战略规划。尽管恢复牡蛎礁所提供的生态系统服务功能，是开展恢复工作时常被提及的理由，但利用生态系统服务功能来指导大规模牡蛎栖息地恢复计划的实例却很少。目前，佛罗里达州彭萨科拉湾系统正在实施这样一种方法，在那里，广泛的合作伙伴联盟和社区利益相关者正在采用流域方法来恢复牡蛎，目的是为了实现包括栖息地、生态系统服务功能、野生捕捞和水产养殖在内的多个目标。在制定栖息地管理计划的过程中，利益相关者将水过滤确定为一项关键的生态系统服务功能。为支持恢复规划，我们通过将牡蛎栖息地适宜性地图与水动力-牡蛎过滤模型相链接，得出了彭萨科拉湾系统中东部牡蛎提供的水过滤服务功能的空间明确估计值。这种空间明确的模型使我们能够确定恢复后的牡蛎礁有可能提供最大过滤服务功能增幅的区域，并提供恢复后的牡蛎栖息地潜在过滤功能的空间明确估计值。这些信息对于恢复规划和管理以及利益相关者参与、宣传和教育计划都很有用。
