CORDWOOD VOLUME 



The volume ot primary growing stock below 

 sawlog size amounts to about 180 million cords 

 (13.6 billion cubic feet). Seventy percent of the 

 cordwood is of hardwood species; only 30 percent 

 is softwood (table 13). 



The current estimate of cordwood volume is about 

 20 percent greater than reported in 1945, mainly 

 because the volume in hardwood trees in the 10-inch 

 diameter class previously classified as saw timber has 

 been included with cordwood here. 



From a utility standpoint, cordwood can be di- 

 vided into two main classes: (1) Pulpwood, includ- 

 ing all of the jack pine, spruce, balsam fir, hemlock, 

 and about 42 percent of the aspen, and (2) other 

 cordwood, including all other species and that 

 portion of the aspen considered too poor in quality 

 to make pulpwood according to present standards. 



One-third of all cordwood, or 60 million cords 

 comes under the pulpwood classification (fig. 23).

Some of the cordwood of species not conunonly 

 pulped is currently usable for industrial purposes 

 and for fuel. A great deal of it, especially in hard- 

 woods in pole stands, should be considered growing 

 stock for 231'oduction of future saw timber.

 evenly divided between States than the saw tiinber 

 alone (table 14). Hardwoods comprise 70 percent 

 of the total volimic, with aspen, maple, and oak 

 predominating. 



OWNERSHIP 



Private land<jwners, including farmers, control 

 approximately iour-Iifths of the saw timber and half 

 of the cordwood suitable for pulpwood. In saw 

 timber, the private ownership is most notable in 

 hardwood species, where it accounts for 83 percent 

 of the total (tal)le 15, fig. 24).
