WebSummary A Fire Danger (FD) program for a pocket-sized calculator has been developed to provide easy and rapid calculation of McArthur's fire danger indices for grassland and forest fires, a hazard rating and other measures of fire behaviour, together with rederived ancillary computations of a drought index and relative humidity. This allows the … WebGrass dominance increased fire spread area—or equivalently increased fire frequency at any given point. For fire to spread through 50% of the 9 m × 9 m plot area required approximately twice as high an abundance of forbs as of grasses. Grass dominance also resulted in fires that advanced faster, were more intense (higher rates of heat ...
