Moisture content, owing to its direct effect on flammability of forest fuels, must be incorporated into a fire danger rating system. Accurate indicators of moisture content in different fuels are particularly important when separate burning tables are required for major fuel complexes. In the past, the development of such indicators has been hindered by a lack of quantitative information about the amount and distribution of moisture in different fuel layers. The study reported here was carried out to clarify duff-moisture relationships in the duff layer of overmature spruce-fir (Picea glauca (Moench) Voss and Abies lasiocarpa (Hook.) Nutt.) stands and clearcuts and to provide a quantitative basis for stratifying the forest floor according to depth, weight, and/or water-holding capacity.
