Table 2 Litter depth and fine woody fuel loading (mean ± SE) by time-lag class (1–100 h) before (pre-fire; 2018) and after (post-fire; 2019) the Carr Fire by treatment type, including untreated control (Control), hand thinned, mastication only (Mast), mastication and burning (Mast + Burn), and prescribed burn only (Burn Only) and vegetation type (chaparral or oak). FWF, fine woody fuels. Superscripted letters reflect statistically significant differences among treatment types when treatment was a significant factor in the top model. See Tables 6, 7, 8 and 9 in Appendix 3 for the model structure of each fuel category
