Table 46 shows that if all commercial timberland were in excellent range 

 condition, Lewis and Clark County would carry the most AUM's, followed by 

 Powell County. Silver Bow County has the potential to carry the fewest 

 AUM's. In each county, if the range condition was improved, the grazable 

 forest land carrying capacity would increase. The amount of the increase 

 ranged from about a 50 percent increase in Broadwater, Jefferson, and Lewis 

 and Clark Counties to about a 14 percent carrying capacity increase in 

 Beaverhead, Deer Lodge, ^4adison, and Silver Bow Counties.
