output from these nongrowing stock sources is 

 projected to decrease further from the 1970 level. 



Supplies of Roundwood Products 



Harvests of softwood roundwood on the Pacific 

 Coast increased over 17 percent between 1952 

 and 1970 from 3.2 to 3.8 billion cubic feet 

 (table 68). Output of softwood products in board 

 feet increased about 12 percent from 22.4 to 25.2 

 billion board feet (table 69 and fig. 37). 



The Pacific Coast preeminence as a major source 

 of timber products until recently was achieved 

 by a high level of production from forest indus- 

 try and other private lands. Almost all of the 

 recent production gains, however, were attribut- 

 able to increased timber harvests on National

Forests and other public ownerships, with the 

 share of total output from these lands increasing 

 from 23 percent in 1952 to 45 percent in 1970 

 (table 71). Increased production from public lands 

 resulted both from increasing demands from the 

 timber industry and from reappraisals of future 

 growth and utilization potentials. The increase 

 from public lands not only offset decreases in 

 production from private ownerships, but also 

 pushed regional production to an all-time peak. 



With public lands dedicated to a sustained 

 level of production, and with industry faced with 

 deficiencies in harvestable age classes in the near 

 future, somewhat different trends are anticipated 

 (tables 71 and 72). By the year 2000, under the 

 assumptions of these base projections softwood 

 roundwood output is estimated to decrease about 

 12 percent to 3.3 billion cubic feet, including 20.6 

 billion board feet of sawtimber. This drop would 

 be largely a result of a nearly 50 percent decrease 

 in log production on forest industry lands. 



National Forests. — Projected output from Na- 

 tional Forest lands, assuming 1970 levels of 

 management and allowable cuts, remain at about 

 .13 billion cubic feet over the projection period, 

 including about 9 billion board feet of sawtimber 

 (tables 71 and 72). 



Beyond 2020, however, results of recent pro- 

 jections and a recent comprehensive study of 

 National Forests in the Douglas-fir region 6 point 

 to an ultimate falldown in available harvests 

 unless forest management is materially accelerated. 

 For this reason these base projections may over- 

 state supplies actually available with 1970 levels 

 of management.
