tional basis the stand-size class distribution of 

 timber is reasonably good. Something over one- 

 third of the area is in sawtimber. Slightly less 

 but still more than one-third is in stands of pole- 

 timber trees. Seedlings and saplings occupy about 

 one-fifth of the area and nonstocked lands a little 

 less than 10 percent. 



On a sectional basis sawtimber stands predom- 

 inate in the West and Coastal Alaska, mainly 

 because of the 50 million acres of old-growth 

 stands still present, three-fifths of which is found 

 in the national forests. About one-tenth of all 



commercial forest land is still in old-growth saw- 

 timber. Poletimber stands predominate in the 

 North and South. The nonstocked areas of the 

 East, about equally divided between North and 

 South, considerably exceed the western area of 

 either young-growth sawtimber or poletimber 

 stands. The total nonstocked area of about 42 

 mUlion acres is only a little less than the total 

 remaining area of old-growth timber, and is pres- 

 ently contributing little or nothing to future timber 

 supplies (table 18).
