Given the above projections and assumptions, the 

 demand for pulpwood in U.S. mills rises to 128 mil- 

 lion cords in 2000 with a further increase to 178 mil- 

 lion in 2030. These volumes are, respectively, 1.6 

 times and 2.3 times the 77.6 million cords consumed 

 in 1977. As indicated in the tabulation below, the 

 alternative assumptions on growth in population and 

 economic activity have large impacts on pulpwood 

 demand in the decades beyond 1980.

Part of the demand for pulpwood has been met by 

 the use of slabs, edgings, veneer cores, sawdust, and 

 other byproducts produced at primary manufactur- 

 ing plants. Between 19.50 and 1977, use of these mate- 

 rials increased from 1.2 million cords to 31.8 million 

 cords. Most of the economically available supplies of 

 such material are currently being utilized, either for 

 pulp production, fuel, particleboard manufacture, or 

 for export. Competition for the available supplies of 

 byproducts is likely to intensify. As a result of this 

 and the projected slow growth in domestic lumber 

 production, followed by a decline toward the end of 

 the projection period, the volume of byproducts used 

 for pulpwood is expected to show little change from 

 current levels. However, as a prpportion of total 

 pulpwood use, residues decline from 41 percent in 

 1977 to 25 percent in 2000 with a further drop to 19 

 percent by 2030. 



Projected Demand for Other 

 Industrial Timber Products 



As shown in the following tabulation, a variety of 

 other industrial roundwood products is consumed in 

 the United States. 



The demand for pulpwood more than doubles by 2030 — most of 

 the increased demand will fall on domestic forests.
