Growing salt marshes

Overview

Healthy salt marshes and mudflats play a critical role in coastal protection and stabilization. Marsh  vegetation captures sediment in the intertidal zone, raising the level of the ground and reducing incoming waves. Growing salt marshes entails creating the conditions and elevations for marsh plants to establish, considering salinity, inundation time, hydrodynamics, substrate, sedimentation, and species management. Reconstruction efforts integrate enhanced shelter from wave attack in areas with sufficient presence of fine sediment to stimulate marsh growth.
