Cut Is Mainly Softwood Sawtimber 



Timber cut is the term used to describe the 

 volume of standing timber that is cut for various 

 timber products or destroyed in logging whether 

 removed from the woods or left unused. It in- 

 cludes, therefore, logging residues and is equiva- 

 lent to "commodity drain" as used in the 1945 

 Reappraisal. 



Of the 10.8 billion cubic feet of growing stock 

 cut for timber products, 1.7 billion was cut from 

 poletimber. This means that 84 percent was cut 

 from sawtimber-size trees, and demonstrates how 

 heavily the cut leans to the larger size sawtimber 

 (fig. 22). Whereas 84 percent of the cut is from 

 sawtimber, only 73 percent of the total inventory 

 is in sawtimber. This means a trend toward 

 smaller size trees. 



The flow of timber products from growing stock 

 to end product in 1952 is graphically illustrated in 

 figure 23, which shows the growing stock input 

 from both East and West, the amoimt from cull 

 and dead trees, and net imports, as well as losses 

 due to logging and plant residues, and the final 

 products. 



Three-Fourths of Sawtimber Cut Is for Saw 



Logs 



Of the 48.8 billion board-feet of live sawtimber 

 cut in 1952, an estimated 36.6 billion feet, or 75 

 percent, was utilized for saw logs. The next 

 largest volume, or slightly under 10 percent of the 

 total, was for pulpwood. Four principal items, 

 saw logs, pulpwood, veneer logs and bolts, and 

 fuelwood, accounted for about 95 percent of saw- 

 timber cut (table 31). 



Three-Fourths of Sawtimber Cut Is Softwood 



About 36.6 billion board-feet, or 75 percent of 

 total sawtimber cut in 1952, was softwood. Soft- 

 wood likewise comprised about the same percent- 

 age of total growing stock cut (table 31). Soft- 

 woods accounted for practically the entire cut in 

 the West. In the South about three-fifths of 

 the cut was softwoods, but in the North the cut 

 of hardwoods predominated in both sawtimber 

 and growing stock.
