Figures 6 and 7 illustrate examples of the transfer of fuel between the live and 

 dead categories for perennial and annual grasses. Typically, herbaceous moisture will 

 be somewhere near 250 percent at the completion of greenup. But these examples illus- 

 trate that given a dry spring or late greenup, the herbaceous moisture will peak at a 

 lower value. 



Figure 6 . — The moisture content of live plants controls the transfer of fuel load be- 

 tween dead (1-h TL) and live herbaceous categories. The slove assigned to -perennials 

 prevents a complete transfer of fuel load from live to the 1-h TL category until a 

 freeze occurs.
