POTENTIAL INCREASES IN TIMBER SUPPLY 

 FROM IMPROVED UTILIZATION 



In addition to increased timber output from 

 cultural measures as illustrated above, there 

 appear to be substantial opportunities for extend- 

 ing timber supplies by improvements in timber 

 utilization. 



Assumed Improvements in Utilization in Base Pro- 

 jections 



As indicated in Chapters I and II, substantial 

 progress has been made in improving utilization of

timber on logging operations and in the processing 

 of timber products. Nevertheless, in 1970 — a 

 rather poor year for the timber industries — nearly 

 1 billion cubic feet of plant residues was burned or 

 discarded. On logging operations an additional 1.6 

 billion cubic feet of logging residues from growing 

 stock, plus sizable volumes of limbs and other 

 material from cull and dead trees, was left in the 

 woods unutilized. Residual rough and rotten trees 

 passed by in logging also represented a major 

 potentiaf source of fiber. Unsalvaged mortality of 

 widely scattered trees lost to fire and other des- 

 tructive agents totaled an estimated additional 4.2 

 billion cubic feet.
