Fuel loading, fireline intensity, and expected fire size were determined after harvesting small-stem lodgepole pine stands. Curves relating predicted fireline intensity to slash fuel loading and windspeed are presented. Removing about 15 tons per acre of residues reduced fireline intensity by half, but in some situations it still was too high to allow direct suppression. Effects of cutting level, method of felling, fuel removal, lopping, and slash age on expected fire size were evaluated. Commercial thinning with directional felling reduced expected fire size to that of undisturbed forest within 5 years. Nominal lopping was ineffective in reducing expected fire size. Methods for managers to use in appraising slash fuel hazard are reviewed. Economic analysis of fuel treatment is discussed.
