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.
