From: Fuel dynamics after a bark beetle outbreak impacts experimental fuel treatments
Crown fire potential (mean and standard error) by treatment following the northern Rocky Mountains’ Fire and Fire Surrogate Study’s fuel treatments (completed in 2001) and regional mountain pine beetle outbreak (2005 to 2012). C = Control, BO = Burn-only, TO = Thin-only, TB = Thin+Burn. Probability of torching is the probability of surface fire ascending into crowns given Monte Carlo simulation; crowning index is the 6.1 m wind speed required to cause active crown fire. Letters above bars denote pairwise differences between treatments (lowercase = 2002 differences, uppercase = 2016 differences); letters are not shown when ANOVA tests were not significant.
