Table 3 Weibull median probability interval (WMPI) in years (yr ± one standard error of the mean), minimum interval (MIN), and maximum interval (MAX), considering all fire scars sampled, only those present in ≥10% of scarred trees, and only those present in ≥25% of trees, in fir-, pine–fir-, and pine-dominated forests in the Monarch Butterfly Biosphere Reserve, Mexico
