Table 15 — Weibull distribution functions for determining delay to germination for advance best 

 trees. The form of the equation is DELAY = e[-ln(1-X)]^"^ + 1 . Categories left 

 blank use the corresponding coefficient for no budworm. "X" is a random number 

 drawn from a uniformly distributed pseudo-random number generator. BWB4 is 

 the number of budworm years in the 5 years before the last disturbance. BAA is 

 the plot residual overstory area, reset to 1 .0 if 0.0
