Observation Narrative	Plot is located on a prominent Holocene dune ridge, with a maximum elevation of ca. 40 ft. Maritime forest is well-developed on the lee side of the ridge. Pinus taeda, Acer rubrum, Quercus velutina and Carya sp. are present in the overstory, while Diospyros virginiana, Ilex opaca, Sassafras albidum and Cornus florida occur in the understory and tall shrub layers. Lianas are abundant and include Vitis rotundifolia, Campsis radicans, Smilax spp., and Lonicera japonica. Ilex vomitoria occurs infrequently in this habitat as an understory shrub. Community rank is B. This area will be developed in the near future; land clearing and road building have already been initiated.
