Logging Methods and Equipment 



Since there was no past experience with near complete harvesting, equipment on the 

 market was studied and a logging system was designed that would have good prospects 

 for economic success. The potential market for residues would be for pulp or recon- 

 stituted wood products; therefore, logging debris had to be chipped. All residue, 

 including bark, limbs, and needles, was chipped in a portable chipper at the landing 

 (fig. 3) . Trees were felled with a feller-buncher (fig. 4) and were skidded with both 

 rubber-tired and crawler skidders (fig. 5) . Logs were bucked and limbed with chain- 

 saws at the landing, loaded on trucks with a heelboom loader, and were hauled to mill 

 by contract haulers. 



All of the merchantable logs were transported 40 miles to the U.S. Plywood mill 

 at Dubois, Wyoming. Part of the chips produced at the site were used for experimental 

 pulping and particle board manufacture by Champion International and the U.S. Forest 

 Products Laboratory. The remainder will be used for experimental spreading over test 

 plots at the site, or disposed of off site.
