The following technical note TN provides a summary of marsh assessment, design, implementation, and monitoring at three salt marsh restoration projects undertaken to address the effects of relative sea level rise RSLR. This TN synthesizes the findings from a 2016 summer webinar series and also incorporates supplemental information on restoration implementation. BACKGROUND Recent research has focused on how salt marshes manifest symptoms of distress due to RSLR, how to properly diagnose stressors associated with observed salt marsh degradation, how to identify appropriate restoration techniques to address the specific causes of distress, and how to assess the immediate and long-term responses to restoration actions. A research work unit entitled Restoring and Sustaining Ecological Function in Coastal Marshes Affected by Sea Level Rise funded by the Ecological Management and Restoration Research Program EMRRP is currently investigating these topics. Ultimately, the work unit will develop a technical framework delineating the ecological and environmental considerations relevant to the restoration of existing, distressed salt marshes for the purpose of offsetting the effects of RSLR. The framework will make recommendations based on a synthesis of published literature and information from ongoing collaborations at three field demonstration projects, thereby, capturing existing information and identifying data gaps.
