DescriptionCharacteristics of upland forest floors under mature jack pine and aspen in northeastern Minnesota were investigated. These fuel measurements were needed as inputs for fire behavior prediction models -- useful for fire management decisions. The forest floor weight averaged 33,955 kg/ha and depth averaged 7.1 cm. Bulk density averaged 17 kg/m3 for the L (litter) layer, 45.7 kg/m3 for the F (fermentation) layer, and 61.6 kg/m3 for the H (humus) layer. The L layer was found to consist of 65 percent foliage, 31 percent wood and bark, 2 percent herbaceous vegetation, and 2 percent miscellaneous. No significant differences were found in weight, depth, or bulk density, except for the bulk density of the H layer, between the forest floors of jack pine and aspen.
