increase to offset the proportional decline in 

 western species. 



Differences between the three species groups in 

 timber removal of growing stock are not so pro- 

 nomiced as in sawtimber. Eastern forests, with 

 greater area and more timber of pole and seedling 

 and sapling size, are capable of supporting a much 

 larger share of total timber removal of growing 

 stock than are western forests. 



At the medium demand level in 1975, western 

 species will supply 5.4 billion cubic feet of timber 

 removal of growmg stock — 37 percent of the total, 

 while eastern hardwoods and eastern softwoods 

 will each supply 4.6 billion cubic feet (table 283). 

 By 2000, removal of growing stock of western 

 species will have risen to 7.0 billion cubic feet, but 

 this is 32 percent of the national total. Eastern 

 hardwoods and eastern softwoods will each supply
