including about 62.5 billion board feet of saw 

 timber, 50 years hence (39). It has proposed a 

 growth goal of 20 billion cubic feet including 72 

 billion board feet of saw timber to meet domestic 

 needs, permit some exports, and insure ample sup- 

 plies for national security. 



The Lake States region has SiA percent of the 

 Nation's population, more than 9 percent of its 

 farms, 9i^ percent of its railroad mileage, 10 per- 

 cent of its construction activity, and 12 percent of 

 its manufactures. Thus its people and its industries 

 could be expected to require at least the quantities 

 shown in table 32 which amoimt to only 8.3 percent 

 of the estimated total cubic-foot requirements and 

 6.4 percent of the forecast of national saw-timber 

 requirements. 



The total potential requirement 50 years hence in 

 terms of standing timber is 1,300 million cubic feet, 

 nearly twice the present allowable cut (fig. 42). 

 This provides no margin for possible new uses nor 

 for a security reserve such as ^vas included in the 

 national growth goal (39). 



Capability of the Land 



In order to supply potential requirements for 

 timber products plus a margin for export, ne^v uses, 

 and secinity, the Forest Service, United States De- 

 partment of Agriculture (39), has proposed a na- 

 tional growth goal which includes 3,100 million 

 board feet and a total volume of 1,150 million cubic 

 feet annually froin the Lake States. It did not 

 specify kinds of wood, but consumption habits sug- 

 gest that at least one-third of the saw timber and an 

 even larger proportion of the total cubic volume

Yields from Natural Stands 



It has been sho\vn that gro^vth and yields from 

 existing stands and naturally restocked areas can be 

 increased greatly by selective logging, closer utiliza- 

 tion, opening up inaccessible tracts, salvaging dam-
