Summary of community characteristics for overwash zones and adjacent undisturbed dune and swale environments on two barrier islands along the Atlantic Coast of Virginia, USA.

Species richness and diversity (Shannon Index, H′) values are calculated across all sampling quadrats within each habitat class. Cover is calculated as the mean (± standard error) for all sampling quadrats for a given class. An * denotes a significant difference in percent cover between similar habitats on the two islands. Lowercase letters denote significant differences among habitat types on the same island.
