Abstract

This interdisciplinary research project will explore the role of small-scale, community-based restoration projects in facilitating enhanced resilience within both human and ecological systems. This project will increase knowledge of the processes through which human engagement in ecosystem restoration promotes beneficial feedbacks within coastal ecosystems. It will enhance understanding about the specific pathways through which restoration disrupts degraded ecosystems and influences human behavior. A large number of complementary, integrated datasets will be assembled, allowing the project to provide a system-level assessment of ecosystem services related to coastal restoration. The project also will explore the potential for changes in human perception and a sense of place to create feedbacks through altered human behavior that impact natural system dynamics. In addition to its fundamental intellectual merit, the project will yield a diverse set of positive broader impacts. It will quantify relationships between restoration success and impact within and between human and natural components of coastal ecosystems in order to improve likelihoods that future restorations will effectively reduce human vulnerability and improve ecological function. The investigators will engage local research participants, such as fishermen and business owners, in ecological restoration and in the use of techniques like participatory geographic information systems. They also will engage elementary and secondary school educators and students in research through hands-on workshops focused on using digital technologies for storytelling, mapping, and data analysis. Significant attention has been given to the degradation and exploitation of natural resources, but ecosystem restoration represents an activity through which humans seek to improve natural systems. Despite growing investments in restoration, a critical knowledge gap persists in understanding what constitutes "success" and whether traditionally accepted metrics of restoration success (such as the survival rate of plantings or the number of volunteers who participate) are truly indicative of measurable "impacts" (such as improvements to ecological function or enhanced stakeholder buy-in). The investigators will leverage a decade-long monitoring dataset for more than 80 oyster reef and living shoreline restoration projects that have involved over 51,000 volunteers spanning along Florida's Indian River Lagoon. They will generate experimental data to examine restoration impacts on local and regional biogeochemistry, hydraulics, sediment transport, recreational fisheries, and threatened or endangered wading birds. Combining these restoration-impact measures with traditional restoration success metrics for both site- and lagoon-scale ecosystem responses will provide a more complete and quantitative understanding of restoration outcomes. They also will conduct a comprehensive assessment of stakeholder perceptions, attitudes, and the creation of a "sense of place" within the restored and surrounding natural system. Research products will create highly transferable knowledge regarding the critical attributes of restoration and local community engagement that cascade into beneficial feedbacks between humans and restored ecosystems.
