NMDS of the species abundance (basal area) of all vegetation plots from the Coastal Plain of North Carolina surveyed in this study (solid circles) and 16 sites with historic data (open circles), surveyed in 2003 or 2009 by the Carolina Vegetation Survey. Arrows connect plots that were resurveyed in the same location; bolded arrows denote that the original survey was conducted in 2003. Common taxon positions in species space are denoted by their species code and grouped to avoid overlapping labels for clarity. ACRU, Acer rubrum; JUVI, Juniperus virginiana; LIST, Liquidambar styraciflua; LITU, Liriodendron tulipifera; NYSP, Nyssa sp. (biflora or sylvatica); PISE, Pinus serotina; PITA, Pinus taeda; QUSP, Quercus, multiple species; TADI, Taxodium distichum.
