Avoca Island - Coastal Marsh Restoration Project

Restoration Strategy: Restoration on 1,014 acres of coastal marsh will be accomplished through installation of 3 water control structures and refurbishment of 15,650 linear feet of exterior levee. Specific objectives of this project include: (1) increase percent coverage of emergent vegetation, 2) increase diversity of emergent vegetation, 3) increase percent coverage of submerged aquatic vegetation, 4) reduce salinities, and 5) maintain water levels at or below marsh levels. In marshes where salinity levels can be managed, such as those in the project area, re-establishment of submerged aquatics typically leads to plant succession, eventually restoring degraded open areas to emergent marsh.
