Although the EMC changes converge at low EMC's, 

 the high temperature data have higher intercepts than 

 the other temperatures, and low temperature data tend 

 to have lower intercepts. This is indicated in figure 6, 

 which shows how the In(AG) changes with EMC. The 

 species were grouped visually and statistical tests were 

 carried out at the 5 percent significance level to see if the 

 regression lines in a proposed group were parallel and 

 coincident. In a few cases, species could be grouped, but 

 the results were not uniform. No consistent groupings 

 were found for the recent cast or weathered conditions. 

 The reason appears to be that the mean square errors, 

 MSE, are so small that slight variations make significant 

 changes in the computed F values. Instead of grouping by 

 statistical methods, overlays were used to see if grouping 

 by litter types was possible. Inspection indicated the best 

 resolution of the litter types was obtained using ±2 percent 

 EMC bands to group the foliar Htter types. At 300 °K 

 (80 °F) and both sorption processes the following groups 

 could be separated in order of increasing EMC: 



Recently Cast Litter 



Group 1: Cheatgrass 



Group 2: Douglas-fir, Engelmann spruce, grand fir, 



and subalpine fir 

 Group 3: Ponderosa pine, lodgepole pine, and western 



redcedar 



Group 4: Quaking aspen, western larch, and western 

 white pine 



Weathered Litter 



Group 1: Cheatgrass 



Group 2: Douglas-fir, Engelmann spruce, and sub- 

 alpine fir 



Group 3: Ponderosa pine, grand fir, lodgepole pine, 



and western redcedar 

 Group 4: Quaking aspen, western larch, and western 



white pine
