Make Way for Marshes
Sea Level Rise Poses a Threat to Tidal Marshes
Rapidly rising seas threaten to drown tidal marshes and diminish the benefits provided to people and wildlife by these valuable coastal ecosystems. Increasingly, government agencies and non-government organizations are harnessing the power of computer-based models of marsh ecosystems to inform management and policy strategies to sustain tidal marshes, including by allowing marshes to shift gradually inland with sea level rise onto formerly dry land—a process known as marsh migration. In response to a need identified by its members and partners, the Northeast Regional Ocean Council (NROC) sponsored an initiative in 2014-15 to advance the effective use of models of marsh migration in the context of management and policy.
Models Provide Information to Support Management and Policy Decision-Making
The report Make Way for Marshes: Guidance on Using Models of Tidal Marsh Migration to Support Community Resilience to Sea Level Rise covers the entire modeling lifecycle from developing a modeling approach and working with data to communicating modeling results. The guidance was developed through expert interviews, a regional workshop of practitioners and scientists, and a scientific and technical literature review. While some of the information pertains specifically to NROC’s region of interest in the northeastern United States, the report is also intended as a useful resource for modeling of marsh migration in other regions.
