Pure stands of lodgepole pine are a major component of forest lands in the Rocky 

 Mountains. The stands consist of numerous stems per acre, which are small diameter, 5 to 9 

 inches d.b.h. Frequently about half the per-acre volume is dead standing and down trees. 

 Table 1 points out the size classes, volumes, and sizes of these stands. Thirty-two 

 billion board feet of sawtimber occur on 7.4 million acres. In general, a large portion 

 of these stands are marginally operable because of high logging costs. 



Because lodgepole pine comprises so much of the forests of western North America, 

 there is growing interest in alternatives to the large, expensive tractors, skidders, 

 and harvesters commonly used for harvesting timber. Close utilization of the stands, 

 both as a means of extending wood supplies and as a means of disposing of the large volumes 

 and deadwood associated with overmature timber, is also of wide concern. Therefore the 

 results of this study should be useful beyond the original purpose and scope of the work.
