 in this chapter. 



2 Includes roundwood products from rough and rotten 

 trees, dead trees, and trees on noncommercial and non- 



forest land. Also includes saw logs from trees less than 

 sawtimber size. 



Note: Estimates are for trend levels and consequently 

 may differ from actual figures for the specified years. 



and sawtimber shown in these tables reflect both 

 harvesting of timber and volumes withdrawn for 

 other purposes. Timber removals on the Pacific 

 Coast are dominated by softwoods; hardwoods 

 account for a very small portion of the inventory 

 and a negligible portion of removals. 



Not all timber removals are available to the 

 forest industries in the form of roundwood prod- 

 ucts such as saw logs, veneer logs, and pulpwood. 

 In 1970 roundwood products made up only 85 

 percent of the softwood removals from growing 

 stock on the Pacific Coast (table 70). Logging 

 residues accounted for 12 percent, and other re- 



movals of softwood timber on lands transferred 

 to other uses an estimated 3 percent of the total. 



In these base projections, it was assumed that 

 the proportion of timber harvests left as logging 

 residue would drop to about 11 percent of re- 

 movals. Other removals were assumed to remain 

 close to the level of 1970. 



In addition to output from growing stock, sub- 

 stantial quantities of roundwood products have 

 been produced from dead and rough and rotten 

 trees in old-growth stands. Decreasing amounts of 

 small trees of less than sawtimber size as defined 

 in 1970 also have been used as saw logs. Future
