MarshGuard System

Coastal Land Rebuilding, Passive Marsh Regeneration

MarshGuard: “Artificial Wetland”, Where, When & How Long Needed

Controls wave-edge erosion, causes sediment deposition & creates habitat.

Devices are lightweight, easily transported & fully adjustable in-the-field. Anchors hold with 2,000lb of attachment force. Unaffected by encasement in solid ice.

Artificial Reef Habitat: Each device contains hundreds of “slots” providing instant high-density habitat. Fish and shrimp shelter in these slots creating a productive heterogeneous ecosystem.

Arrays are advanced to progressively reclaim land. Reusable in new deployments.

Fire Island National Seashore (FINS) project to rebuild access road shore

USFWS & DU deployed MarshGuard to build mudflat elevation, which spartina naturally colonized. 

As the mudflat is stabilized, the array will be advanced to passively generate new wetland.
