Marsh Migration Group

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, NROC sponsored an initiative in 2014-15 to advance the effective use of models of marsh migration in the context of management and policy.

The Marsh Migration Group is one of two NROC groups engaged in Resilient Shorelines, along with the Living Shorelines Group.

Featured Activities & Products

Workshop: Using Technology and Emerging Practices to Improve Tidal Marsh Habitat Resiliency

Available documents include the workshop agenda, list of attendees, and presentations given during the various sessions: marsh models – state updates, model applications for tidal habitat resiliency planning (coming soon), nonstructural management practices that build resiliency, structural management practices that build resiliency, and the Mills River field trip.

Make Way for Marshes

Make Way for Marshes

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 life-cycle.


Tidal Crossings Assessment Workshop

Available documents include the Workshop Agenda and a list of participants. Subsequent to this regional workshop in Sept. 2015, a number of partners in New Hampshire completed development of NH’s Tidal Crossing Assessment Protocol, which now serves as a screening and prioritization tool.
