1 Includes output from cull trees, dead trees, and trees 

 less than 5.0 inches in diameter on commercial forest land 

 and output from trees on noncommercial and nonforest 

 lands. 



2 International J-i-inch rule. For sawlogs log scale vol- 



ume was assumed to equal lumber tally. 



3 Less than 0.5 million units or cubic feet. 



* Includes hewn ties, box bolts, shingle logs, excelsior 

 bolts, turnery bolts, chemical wood, and bolts for other 

 miscellaneous products. 



Nearly all saw logs were produced from growing 

 stock, whereas about 15 percent of the veneer 

 logs produced in the United States in 1962 came 

 from dead and cull trees. Nearly 10 percent of 

 the round pulpwood output also came from such 

 nongrowing stock sources. In the case of fuel- 

 wood, more than half the total roundwood used 

 came from cull and dead trees and other non- 

 growing stock sources. 



For all round products combined, 86 percent 

 came from growing stock in 1962 and 14 percent 

 from nongrowing stock sources. It was estimated 

 that the proportion of roundwood products de- 

 rived from growing stock would increase somewhat 

 over the projection period to about 90 percent of 

 all roundwood, with corresponding reductions in 

 the percentages obtained from dead and cull trees 

 or other nongrowing stock sources. This assump- 

 tion is based on the expectation that available 

 supplies of salvable dead timber will decrease 

 with the steady reduction in the area of old- 

 growth timber that is taking place. Also, in- 

 creased thinnings and other cutting to anticipate 

 mortality is considered likely to result from 

 further road development and better management 

 practices. 



Timber Cut Projected To Rise 

 86 Percent by 2000 



In contrast to the slight rise in total output of 

 industrial roundwood from all sources between 

 1952 and 1962, shown in table 45, the estimated 

 timber cut from growing stock dropped about 

 6 percent between 1952 and 1962 (table 48). The 

 cut of sawtimber, however, was approximately 

 the same in both years. These divergent trends 

 in total roundwood output and in timber cut 

 appear to have resulted largely from greater use 

 of nongrowing stock material and closer utilization 

 of tops and other formerly unused portions of 

 felled trees. 



Projections of timber cut from growing stock — 

 assuming no changes in available sizes of timber 

 in the future — rise from 10.1 billion cubic feet 

 in 1962 to 18.8 billion cubic feet in 2000 (table 48). 

 Projections for sawtimber rise from 48.4 billion 

 board feet in 1962 to 83.9 billion board feet by 2000.
