1 Cordwood volume of trees under sawlog size, whichincludes the wood and bark of the main stem to a usable to|i. The minimum allowable top was 

 never less than 4 inches and seldom more than 8. Cordwood volume was calculated on a basis of 80 cubic feet per cord for hardwood species and 90 cubic 

 feet for pine and cypress. Only woods cull was deducted from cordwood volume. 



* Of the total elm volume, approximately 51 percent is cedar elm, 42 percent white elm, and 7 percent winged and red elm. 

 3 Approximately 33 percent of this volume is black gum. 



* Approximately 23 percent of this volume is hickory. 



small part of the total high-grade volume, less than 

 400 million board feet, is found on noncommercial 

 forest areas. 



Four species groups show total net volumes of 

 more than 1 billion board feet each (fig. 7 and 

 table 7). Water oaks lead with almost 1% billion 

 board feet, overcup oak is second, and red gum and 

 bitter pecan follow in order. Of the total volume 

 of 9 billion board feet, 28 percent is in high-grade 

 logs. This volume of high-grade material is dis- 

 tributed among the species as shown in figure 7. 



Considering total board-foot volumes by species on 

 commercial forest areas, red gum leads with over 

 900 million board feet. The water oaks, willow, 

 Cottonwood, overcup oak, and elms follow in order. 



Cordwood Volume 



In addition to saw-timber voluine, living trees, 

 both sound and cull, contain approximately 31 

 million standard cords (4 by 4 by 8 feet) of sound 

 wood not suitable for saw tiinber. This cordwood
