amounted to 11.1 billion cubic feet of roundwood, 

 including 54.7 billion board feet of sawtimber 

 (table 13). 



In addition to roundwood harvests from growing 

 stock, significant quantities of roundwood — about 

 1 billion cubic feet in 1970 — were produced from 

 rough and rotten trees, dead trees, and other 

 nongrowing stock sources such as trees growing 

 on low site forest lands and in fence rows and 

 shelterbelts. 



Total harvests of roundwood timber products 

 from all sources thus amounted to an estimated 

 1970 "trend level" of output of 12.2 billion cubic 

 feet. Harvests of sawtimber amounted to 54.7 

 billion board feet, and all sawtimber size material 

 including logs from nongrowing stock sources

amounted to an estimated 59 billion board feet 

 (including 46.9 billion board feet of softwoods and 

 12.3 billion board feet of hardwoods). 



Saw -log harvests. — Saw logs were the most 

 important single product produced' from U.S. 

 forests in 1970, with output amounting to 6.2 

 billion cubic feet (table 13). This harvest repre- 

 sented about 36.2 billion board feet of sawtimber 

 plus about 3.0 billion board feet from other 

 roundwood sources. 



Western forests supplied more than half of the 

 total saw logs produced in 1970, and more than 

 one-third of all roundwood products (table 14). 

 Although the West has maintained this relatively 

 high proportion of total output for more than two 

 decades, production on the Pacific Coast has been 

 increasingly supplemented by production in the 

 Rocky Mountain States. 



All but 3 percent of the hardwood saw logs 

 harvested in 1970 came from the eastern States, 

 with the cut about equally divided between the 

 North and South. Oaks made up a sizable part of 

 the saw-log harvest in the East. In the South, 

 yellow-poplar and gum were also important com- 

 ponents of the timber harvested. In the North, 

 maple, cottonwood, aspen, elm, and birch were 

 the principal species cut. Production of alder for 

 the furniture industry has also become of impor- 

 tance in the Pacific Northwest. 



Saw-log production in the United States in 1970 

 was at about the same level as reported in 1952, 

 but materially higher than in 1962 (fig. 10). Recent
