Timber 



quality 



class 



Tree and stand characteristics 



GOOD 



Trees well formed, without injuries from fire or other cause, practically free of rot. Natural pruning good for 

 age of stand. Stand generally uniform and even-aged and on good to average land class. 



Douglas Fir would have good poles and piling with a high proportion of peelable blocks (over 18" diameter) in 

 the larger trees. Sawlogs would average 50% or more #2 second growth grade. 



AVERAGE 



Trees generally well formed but with normal amount of defect and injury from fire, rot and other causes. Pruning 

 fair to good for age of stand but with tendency to limbiness in younger aged trees. Stand uniform to scattered 

 clumps, even and mixed ages. On average to good quality forest land. 



Douglas Fir would have scattered poles and piling, a few peelable blocks (over 18" diameter) in the larger trees 

 and sawlogs would run 25% to 50% #2 grade. 



POOR 



Unusual amount of deformity or injury in stand. Rot common. Trees limby. Mixed ages. Stand scattered. Log 

 poles and piling of low grade.
