harvesting and processing all make possible fuUer

 fields will help in meeting future timber needs. 



What has been said about increasing use of 

 woods and plant residues has significance chiefly 

 with respect to the softwoods which present the 

 most critical supply problem. Such considerations 

 are of secondary importance for hardwoods. With 

 hardwoods the problem is not primarily supply, 

 but rather demand. 



The challenge of underutilization of hardwoods 

 is perhaps the major issue brought out by the 



analyses of growth, cut, and use. Hardwood 

 volume is accumulating and annual growth of 

 hardwoods is increasing. Yet hardwood cut has 

 fallen off since the end of World War II. Hard- 

 wood forest types comprise more than half the 

 total commercial forest area. They are expanding 

 at the expense of softwood types. The excess of 

 annual growth over cut for hardwoods is of little 

 consequence when there is so little evidence that 

 a more abundant supply will bring forth com- 

 mensurate increase in demand. Fuller utilization 

 of hardwoods should help to take the pressure off 

 the softwoods.
