Not all the 42.4 billion board feet of saw timber is of 

 sufficient size and quality or in sufficient concentration for 

 practical logging by operators of sawmills and other 



forest-industry plants under prevailing market conditions 

 and requirements. Accordingly, the forest areas were 

 classified on the basis of timber quality and volume per 

 acre.
