Fire Ecology

Table 5 Relationship between nonmetric multidimensional scaling (NMDS) axis values and environmental variables for burned plots (presence/absence, all strata, n = 86). Values shown are Pearson correlation coefficient “r” for continuous variables, and Kendall’s “tau” for ordinal/ranked variables. Values significant at P < 0.001 are bolded, and P < 0.01 in italics
