Specific gravity : 0.48 0.48 0.40 0.40 0.30 a = the nonhorizontal angle correction factors The correction factor adjusts weight estimates for the fact that all particles do not lie horizontally as assumed in the planar intersect theory. Brown provides the following: 0 to 3 inches: 1.13 3+ inches: 1.00 Nl = the total length of the sampling line These lengths are different for different protocols: FIREMON Sampling Scheme: Fuel Size Class Length of Transect Sampled 1-hr 6ft 10-hr 6ft 100-hr 15ft 1000-hr 60ft II. Litter and Duff: Litter and Duff loadings are calculated by multiplying the average depth by the bulk density of litter (or duff). Use bulk density values of 2.75 lbs/ft3 for litter and and 5.5 lbs/ft3 for duff. Note that you will need to convert to tons/acre. III. Live and dead herbaceous and woody loads:
