PR = perennial rhizome grass, PB = perennial bunchgrasses, PF = perennial forbs, SS = shrubs and semi-shrubs, AB = annuals and biennials.

For each species pair, the upper number is Spearman’s rank correlation coefficient (r), and the number in parentheses is P value.

The symbol, “-”, denotes no statistically significant correlation.
