Forest foliage that comprises much of the forest floor litter has higher equilibrium mois- 

 ture content, EMC, than woody components. The EMC's at 300 °K were found to increase 

 as follows: grasses < fir-spruce needles < pine-cedar needles < aspen leaves-larch 

 needles. Equations that express Gibbs free energy associated with moisture content were 

 used to develop regression equations that predict the EMC's from temperature and rela- 

 tive humidity, RH, for temperatures between 278 °K (40 °F) and 322 °K (120 °F) and RH's 

 between 1 and 90 percent.
