Open the

CM_Example.cm3

data

file.

Set the proportion cut

to 0 for all trees.

Run these data using

the same environment values as the last problem (the same you have used for quite a while)

.

Enter the results in the

first row

in the

row.

Set the

to 20% for foliage, for all Douglas-fir.

again using the same environment values, the 2005 FBPS Fuel Model Set with slash carrying the fire (I know slash is questionable, but use it an

yway)

and enter in the

Defoliation

row

.

Complete the table below.
