Transcript of Coastal Weland Management and Adaptation Straegies
Methods, Partnerships and Resources
SLAMM Municipal Workshop October 26 & 28, 2014
Adaptation Strategies Upland
Changing / moving land use activities that inhibit marsh migration
Adopting activities that facilitate marsh migration Removal of physical barriers
In-Marsh
Drainage improvements (runnel / creek excavation) Elevation enhancement Erosion control along marsh edge
Elevation enhancement using dredged materials

Living Shorelines Use of “soft” materials to reduce erosion of marsh bank

How can SLAMM Results inform Restoration? Project Prioritization
Critical wetlands analysis
Restoration Strategy Development
Where should we invest now? Which habitats are in danger
of disappearing? Which will persist?
Illustration of the “do nothing” alternative
Important for permitting process, project design and
evaluation
From “Blackwater 2100: A Strategy for Salt Marsh Persistence in an Era of Climate Change”
Current Projects Narrow River Estuary Restoration--$1.8M Post-Sandy Dept. of the Interior funding to US Fish
and Wildlife Service Refuge System Project team developed recommendations for
restoration actions within Narrow River Estuary Project includes Beneficial Re-use / Thin Layer Deposition Micro-creek / runnel excavation Marsh edge enhancement via living shoreline
techniques
SLAMM Results for Middlebridge on Narrow River at 3’ SLR
Current Projects Salt Ponds Region Salt Marsh Restoration--$3.25M Dept. of the Interior Competitive post-Sandy grants
program Partners: CRMC, USFWS, Salt Ponds Coalition,
Towns of Charlestown and Westerly, Save The Bay Beneficial reuse for marsh restoration at Ninigret
Pond, planning for projects in Quonochontaug and Winnapaug Ponds
Multiple benefits to ecosystem and recreational use
