Experimental Design and Data Collected: Fuel moisture sample categories were determined so as to be representative of the types and
distribution of the fuel strata within the sample area that could be expected to be consumed in
the prescribed burns. The categories collected were: litter, suspended litter, duff, downed wood
(1, 10 and 100-hr timelag sizes), wiregrass, other grasses, gallberry shrubs and other evergreen
shrubs. An effort was made to collect 10 samples of each fuel category in each burn unit, though
in some cases, fewer samples were collected due to time constraints. Samples were collected
within 1-2 hours of ignition, with the coarser samples (such as 100hr-timelag wood) collected
earlier, and the finest (such as suspended litter) collected last, in accordance with the drying
times of each fuel type. Moisture samples were placed in 12 x 12 inch four-millimeter thick,
re-sealable plastic bags. Bags were labeled with time, date, fuel type and location of
collection (e.g., plot number).
To determine wet mass, samples were weighed within 12 hours of collection on a portable
electronic balance to the nearest 0.1g. Once transferred to the Pacific Wildland Fire Sciences
Laboratory in Seattle, plastic bags were opened to allow samples to air dry and prevent
decomposition. Each sample was placed in a labeled metal container for drying in the lab’s
forced-air drying ovens. Samples were dried at 70⁰ C for 48-72 hours, or until their weight
stabilized. Once dry, samples were weighed with an electronic balance and recorded to the
nearest 0.1g. Gravimetric fuel moisture was calculated as the wet weight of the sample divided
by its oven-dry weight to determine its proportional moisture content.
