Conclusions 



-I 



Estimates of logging residues are important for several reasons. Fir§t of all, 

 they express a reduction in inventory of the residual stand for which no economic re- 

 turn was gained. Second, unless logging residues are included with product volume, 

 the estimate of residual stand volume with which the manager must work in the future 

 is overstated. The consequences of planning future management with overstated esti- 

 mates are obvious. Third, the volume of residues that might be salvaged for fiber 

 production is of interest in areas where there is a market for chips. Logging opera- 

 tions that result in high underutilization of product material are, therefore, costly 

 both now and in the future.
