le also shows the amounts of land in the different timberland quality classes 

 that were assigned to the different treatment opportunity classes (see Table 

 32). 



Because they are not combined with any other treatments, the number of 

 acres in the harvest - high risk and harvest - low risk groups does not 

 change in the treatment class tables. If these "harvest" groups are ignored, 

 the most commonly assigned treatment opportunity classes for excellent and 

 good-rated timberlands in Working Circle 3 were overstory removal (85,800 

 acres), precommercial thinning (73,100 acres), no treatment due to productive 

 condition (65,900 acres), and sanitation (49,400).
