In the West, the situation is quite different and, 

 in terms of sawtimber, growth is only about half 

 of cut, but as previously emphasized this is due 

 to the residual of old-growth timber in the West 

 and recent increases in the rate of timber cut. 



Most Eastern Species Have Favorable Growth- 

 Cut Ratios 



Among eastern softwoods, the major species 

 groups have favorable sawtimber growth-cut ratios 

 except the white, red, and jack pine group. The 

 southern yellow pines, which, of course, dominate 

 the eastern picture, show growth to be 22 percent 



in excess of cut of sawtimber. Among the eastern 

 hardwoods, yellow-poplar has an adverse saw- 

 timber ratio. But for other "soft" hardwoods, 

 growth exceeds cut by more than 50 percent. 

 For a group of so-called "other 'hard' hard- 

 woods" — which includes many relatively un- 

 desnable species — growth is two and one-half 

 times cut. These differences point to declining 

 quality with respect to future timber supply in 

 terms of species composition. The ratio of 

 growth to cut for the various species groups is as 

 follows: " 



" See table 30 for the growth and cut estimates from 

 which these ratios are computed.
