STUDY METHODS 



Inventory Procedures 



A 5-acre (2.02-ha) rectangular block on each of the two sites was laid out and all 

 residue more than 8 feet (2.44 m) in length and 3 inches (7.62 cm) in diameter (small 

 end) was measured. Original wood volume on the two study sites and the progressive 

 effects of each treatment on residue amount and character were compared. Conventional 

 logging was measured in board feet, relogging in cubic feet. Much of the residue re- 

 maining after logging was too small to be expressed in board feet. Only residue 3 

 inches (7.62 cm) or more in diameter was measured on the 5-acre (2.02-ha) study areas; 

 residue smaller in diameter was deemed useless. A board foot: cubic foot ratio was 

 computed for comparing the two measurements of volume. 



Relogging Production Procedures 



Two methods of skidding were compared oh a round-trip basis. Miscellaneous pro- 

 duction and nonproduction time was also analyzed. Skidding was timed with a stop watch 

 and the turn pieces and volumes tallied. 



CONVENTIONAL LOGGING 



Utilization Standards and Products 



Sawlogs. --Only green sawlogs (8 feet [2.44 m] long to a 10-inch [25.4-cm] top, or 

 10 feet [3.05 m] long to an 8-inch [20.32-cm] top) containing a minimum of 10 board 

 feet (3 ft 3 ) and more than one-third sound were considered merchantable and were removed 

 from both study areas. "One-third sound" meant that a piece containing a gross scale 

 of 30 board feet must have 10 sound board feet to be merchantable. Rot, sweep, crook 

 and checks were considered defects. Summation of cubic volume contained in residue 

 pieces grossing 10 board feet revealed that an average 10-board-foot piece contained 

 approximately 3 cubic feet. 



Pulpwood. --Although no pulpwood was removed, Department of Lands pulp standards 

 were hypothetically applied to determine how removal of this additional product would 

 have affected residue volumes. 



Pulpwood is defined as green or dead softwoods not merchantable for sawlogs but 

 containing 10 board feet of pulpable material, and having one-third or more of the 

 gross volume in sound wood. 



Rot-infected wood is considered merchantable for pulpwood if the wood fibers can- 

 not be extracted from the end of the log with the fingers. Logs having an unmerchant-
