The goal of wetland restoration/creation projects is to construct a wetland that exhibits the same beneficial functions as the targeted wetland community in the most efficient manner possible. Research conducted on a recently completed seven-hectare (17 acres) tidal marsh in Carteret County, North Carolina helped to quantify planting success of common North Carolina tidal wetland vegetation within the first growing season. A review of literature and surveys of local reference tidal marshes indicated native plants in these areas were distributed at distinct elevation ranges, but little information was available on the success of these species when planted at these elevations during marsh creation or restoration. Some specific research objectives were 1. To quantify the success of greenhouse-propagated Spartina alterniflora, Spartina patens, Juncus roemerianus and natural regeneration in each target elevation range 2. To quantify hydrology and salinity gradients between the specified elevation ranges and 3. To determine if a relationship exists that affects vegetation success.
