Appendix B. A table providing correlations of NMDS axes with vegetation variables.

TABLE B1. Positive and negative symbols indicate the sign of the relationship to the original vegetation variables. One symbol indicates an absolute value for the Pearson correlation between 0.2 and 0.5, while two symbols indicate an absolute value greater than 0.5. Empty cells indicate that the correlation value was less than 0.2.
