Sustained timber removal as shown by the solid line above brings timber removal and pro|ected growth of both softwoods 

 ohd hardwoods into balance by 1985. The increased use of hardwoods needed to attain this bolonce exceeds any trends now 

 in sight. Reduced removal of softwoods needed to reach a balance falls below the removal necessary to supply lower pro- 

 jected demands for softwoods. Moreover, sustained timber removal for all species combined falls below the total removal 

 needed to supply lower projected demands.

' Timber removal and projected growth from lower level 

 calculations not published elsewhere. 



2 Timber removal conforms with removal estimates at 

 lower level (see table 283) and projected growth conforms 

 with projected growth at lower level (table 291). 



3 Actual timber cut (from table 284). 

 * Net growth (from table 281).
