Figure G16. Joint plot showing significant correlations (r 2 = 0.290) of environmental variables
with ordination scores for 56 seepage wetland plots on Axis 1 and Axis 2 of the NMDS
ordination. The angles and lengths of the radiating lines indicate the direction and strength of the
relationship. Environmental variables used in joint plots are listed in Table 5. Plots from the
seven Virginia national parks are labeled to the right of or below the symbol. Only the 56 plots
in this group with complete environmental data were included in the ordination.
