Model-based estimates of the tree litter + duff, herbaceous, and shrub median fuel loads (Mg/ha) across a gradient of pretreatment tree cover at 1, 6, and 10 years after mastication. Data are for sites along a north to south gradient in western Utah experiencing Utah juniper and Colorado pinyon pine expansion. The mean (± SE) increase was 413.4 ± 110.4% in herbaceous fuel load and 232 ± 61.4% in shrub fuel load from 1 to 10 years posttreatment. Note: tree litter + duff fuel loads were not collected (nor estimated) at 6 years posttreatment. Figure from Wozniak et al. (2020)
