byproducts now used as fuel — equivalent to 

 roughly 12 million cords in 1962 — also are likely 

 to be diverted to the pulp industry as use of fuel- 

 wood declines. With these considerations in 

 mind, use of plant residues for pulp wood was 

 projected to increase from 9 million cords in 1962 

 to 20 million cords in 2000. 



Saw logs represented by far the most important 

 product — accounting for 50 percent of the total 

 volume of roundwood consumed in 1962. Pulp- 

 wood made up another 28 percent of the total, 

 veneer logs 8 percent, miscellaneous industrial 

 products 4 percent, and fuelwood 10 percent. 



Total Roundwood Consumption 

 11.8 Billion Cubic Feet in 1962 



Projected Total Demand for 

 Roundwood Nearly Doubles by 2000 



Estimates of roundwood consumption for dif- 

 ferent timber products shown in table 43 in 

 standard units are summarized in table 45 in terms 

 of cubic feet of roundwood used for each product. 



Total consumption of roundwood in the United 

 States has been fairly stable during the past two 

 decades. Use of industrial roundwood, however, 

 has shown an upward trend, with a rise of about 

 4 percent between 1952 and 1962 (fig. 28). 



In 1962 the volume of all roundwood used in 

 producing wood products for U.S. markets totaled 

 11.8 billion cubic feet. This included 10.7 

 biUion cubic feet of industrial roundwood and 1.1 

 billion cubic feet of fuelwood. 



The estimate of roundwood volumes required 

 to meet projected demands for lumber and other 

 timber products rises from 11.8 billion cubic feet 

 in 1962 to 21.3 billion cubic feet in 2000 (table 45). 

 For industrial wood, projected demands rise from 

 10.7 billion cubic feet to 20.8 billion cubic feet. 



These projections of roundwood requirements 

 have been calculated in cubic feet on the basis that 

 available supplies of timber in the future would be 

 similar in size to the timber cut in 1962 and that 

 utilization factors — e.g., board feet of lumber 

 produced per thousand cubic of saw logs, and 

 square feet of plywood per thousand cubic feet 

 of veneer logs — would not change appreciably.
