Abstract: A vegetative study of the U.S. Army Coastal Engineering Research Center's Field Research Facility at Duck, North Carolina, was undertaken from May to December 1981 to determine and document natural or manmade changes which occurred since Levy's (1976) original study. For four seasonal sampling periods (May, July, September, November), his procedures were replicated, his permanent quadrats reestablished and mapped. A vegetation rnap of the area was prepared using aerial infrared photos and ground-truth surveys. Fourteen different plant communities were delimited. Stratified random sampling produced frequency and biomass data for twelve communities and frequency and density data for the two shrub communities. Biomass data were obtained using the clip quadrat method. The distinctiveness of the foredune, sandgrass, sandgrass-buttonweed, sound-side disturbed shrub, and sound-side shrub communities was borne out by the ordination techniques. The interdunal marsh, low dune grass, planted bitter panicum, planted American beachgrass, and roadside disturbed communities showed a strong similarity in all three ordination perspectives. The most visible change that has occured since Levy's (1976) original study was the homogenous mixing and expansion of the planted bitter panicum and planted American beachgrass communities. Floristic collections made throughout the study revealed a flora of approximately 180 species and 151 genera, representing 58 families.
