 be demands for wood within the next 50 years 

 which have not been foreseen. To the extent that 

 withdrawals are made for this purpose, they wUl be 

 additions to timber cut. 



(3) Withdrawal of land from commercial timber 

 production. The long-time trend in the acreage 

 of commercial forest land in the United States 

 has been downward. It is reasonable to expect 

 that urban expansion, the construction of addi- 

 tional highways and reservoirs, and priority need

of forest land for watersheds and recreation will 

 continue to decrease the acreage devoted to 

 growing commercial timber crops. If the remain- 

 ing land is to grow the timber needed, the inven- 

 tory on that land must be buUt up. Consequently, 

 the total growth needed must be sufficient not only 

 to supply the timber cut, but also to build up 

 the inventory on the remaining land to the extent 

 needed to offset the reductions in inventory due 

 to the elimination of land from forest production.
