Table 5 Hoffman and Gardner Importance Index for each FEFM and each fuel type shows that the fuel of relative importance to the total emissions produced varied depending by FEFM. Emissions from measured data and FCCS fuelbeds were most influenced by CWD and duff, and FLM by duff and shrubs, respectively. Highest values are indicated in bold.
