If the assumptions basic to this projection prevail for the next two or three decades, timber removal and net growth 

 thereafter will more closely approach each other than indicated by the heavy lines above. Trends toward limited supplies 

 resulting from inadequate growth will reduce timber removal below omounts needed to supply projected demands. On the 

 other hand higher prices caused by limitations in supply will stimulate forestry and the decline in growth would 

 be modified by this and reduced removal.

Lower Level Demands Can Be Sus- 

 tained for Some Time 



Under lower level assumptions, comparisons of 

 projected growth and needed growth indicate that 

 potential demands can be met for some time. Pro- 

 jected sawtimber growth would increase slowly to 

 the end of the century and would exceed needed 



growth by 4 percent in 1975 (table 292). In 2000, 

 however, projected growth would be 16 percent 

 less than needed growth, and the gap would be 

 widening (fig. 135). Moreover, this comparison for 

 all species groups combined hides important 

 growth deficits for eastern softwoods and western 

 species since projected growth for eastern hard- 

 woods exceeds needed growth in both 1975 and
