Restoration projects, although much <br />easier to permit, are still required to address net functional losses of wetlands, <br />and/or impacts to listed species habitat. The design was undertaken with the goal of <br />creating & enhancing wetland habitats. The islands are dominated by exotic <br />vegetation, there is limited habitat for l sted wildlife species. <br />■ Potential Community Structure: <br />Wetlands - mangroves and saltmarsh, benthic habitat <br />Uplands - coastal hammock <br />Transitional Areas - grasslands, shorelines <br />■ Sustainability/Resiliency: The creation of wetlands on the islands allows for transport <br />of the excavated soil landward to increase the elevation within existing uplands. <br />Raising these areas will allow for creation of maritime hammocks which are <br />increasingly threatened by sea level rise. <br />17 <br />
