= AND PQ-8593 
An isolated pocket of valuable timber killed by insects. Such values are a total loss 
unless the trees can be salvaged before deterioration sets in—-usually a matter of only 
a few weeks. 
TIMBER values are lost following fire and 
insect and disease attacks, and opportunities 
for improving stand conditions are neg- 
lected because of inability of the Forest 
Service to undertake logging operations in 
areas not adapted or attractive to private 
enterprise.
