of mill capacity to western Oregon, but cutting 

 has now reduced the inventory on western Oregon 

 private lands to the extent that existing industrial 

 capacity cannot be maintained there. Within 

 the near future a sizable expansion of industrial 

 capacity in western Washington again appears 

 possible because of a continuing buildup of young 

 stands on private lands cut over in the past 

 century. 



S\zz of Available Timber 

 Expected To Decline 



In the conversion from old-growth to young 

 growth operations, the size of timber cut on the 

 Pacific coast will necessarily decline. In 1962 

 nearly two-thirds of the total cut was produced 

 from trees 29 inches in diameter and larger — 



compared with a projected 27 percent in 2000 

 (table 78).
