Annual timber growth and mortality 145 



Annual timber growth 145 



The South leads in annual timber growth 146 



Southern yellow pine dominates annual 



growth 147 



The oaks dominate eastern hardwood growth. . 148 

 Douglas-fir dominates annual growth in the 



West 148 



Annual growth is increasing 149 



Quality of present growth is declining 150 



Annual mortality 151 



Timber products output and timber cut 153 



Timber products output 153 



More timber harvested for saw logs than for 



all other products combined 154 



Timber cut 154 



Major dependence is on sawtimber 155 



The West leads in timber cut for saw logs and 

 veneer, the South for pulpwood and fuel- 

 wood 156 



Timber cut is predominantly softwoods 157 



An increasing proportion of the Nation's saw- 

 timber cut has come from the West 160 



Comparison of growth and cut 161 



Softwood growth exceeds timber cut in the East. _ 162 

 The more desirable species generally have the less 



favorable growth-cut relations 163 



An excess of growing-stock growth over cut is 



important for continued sawtimber balance 164 



Other significant aspects revealed in sawtimber 



analysis by regions 165 



The relation between growth and cut is generally 



improved over 1944 167

Logging and plant residues 168 



Logging residues 169 



Quantity, source, and location of logging 



residues 169 



Woods utilization improved since 1944 170 



Plant residues 170 



Quantity, source, and location of plant 



residues 171 



Plant residues in relation to input are greatest 

 in cooperage m^anufacture, least in preparing 



wood for pulping 172 



Use of plant residues 173 



Unused residues can help meet additional needs 



for timber products 175 



Trends in utilization 176 



LTtilization in the woods 177 



Improved equipment and logging methods 177 



Expanding markets 177 



Shortages force better utilization of veneer 



timber 177 



Utilization of plant residues 178 



The utilization outlook 178 



Conclusion 179 



The situation with respect to timber growth and 



utilization has improved 179 



Distribution of growth and cut is not well 



balanced 179 



Proportion of hardwood and of inferior species 



increasing 179 



Heavy reliance placed on small group of 



species 179 



Large opportunities for fuller and better use 180
