Abstract

Forest foliar litters that make up the fine fuels involved in spreading wildfires may vary in equilibrium moisture content, EMC, by 7 percent or more. This research reports the differences in EMC by species, the changes in EMC due to relative humidity and fuel temperature, and the predictions of EMC by applying a form of the Gibbs free energy equation. Results show that EMC's of only a few litter types are similar to the EMC of wood and that all litter types exhibited lower EMC's than wood at high temperatures and humidities. Test conditions ranged from 278 "K (40 °F) to 322 °K (120 °F) and from 1 0 to 90 percent RH.
