A SUMMARY OF THE TIMBER RESOURCE REVIEW 



53 



timber cut for lumber is unused, but only 4 percent 

 of that cut for pulp ^° (fig. 24) . About the same 

 proportion (28 and 26 percent) of timber cut is 

 unused in both the South and the West, but the 

 North with 18 percent unused would appear to 

 have significantly closer utilization. 



Logging and unused plant residues can, of 

 course, never be completely eliminated. How- 

 ever, reduction in residues is one effective way of 

 meeting increased needs for timber products and 



'•> The percentage for pulp refers to logging residues 

 only. Plant residues, consisting of wood losses in storage 

 and in preparing the wood for pulping, amounting to about 

 7.5 percent of the roundwood volume, are used as fuel. 

 Not included as residues are the additional losses of wood 

 substance incurred in the various pulping processes, of 

 which about 80 percent are used as fuel or for a variety of 

 byproducts. 



making local timber supplies go further. Reduc- 

 tion in the loss rate for lumber of 34 percent affords 

 the greatest opportunity to stretch supplies, be- 

 cause of both the high rate and the large quantity 

 of material involved. 



In recent years much progress has been made 

 in more efficient use of wood and more can be ex- 

 pected. Better equipment has been developed in 

 both the woods and the manufacturing plants. 

 Likewise, new techniques and processes, both 

 chemical and structural, new uses, and new prod- 

 ucts have all been developed. Inferior species are 

 being used more and with greater effectiveness. 

 The outlook is for a continuation of these trends. 

 It is estimated that by 1975 about 5 percent less 

 sawtimber wiU be needed than now for a given 

 level of products as the result of continued im-
