Abstract 



Lodgepole pine ( Pinus contorta Dougl. ) in Wyoming was logged 

 to near complete standards using a feller-buncher, grapple and 

 choker rubber-tired skidders, and a portable chipper. Cost of re- 

 moving the commercial timber was comparable to costs incurred 

 in conventional harvesting. Cost of removing the logging residue 

 and chipping it on the site shows promise for future utilization. A 

 more efficient logging system is simulated and proposed for reduc- 

 ing the costs of near complete harvesting in the future.
