Indicator factors 



The cull indicator factors for Sitka spruce are given in 

 table 6, those for western hemlock in table 7^ and for western red- 

 cedar in table 8. These tables provide cull discount factors for 

 the gross board-foot and the gross cubic-foot volumes of trees that 

 have no cull indicators, of trees with cull indicators on only one 

 section of the bole, of trees with indicators on both sections of 

 the bole, and of all trees with indicators. They express the per- 

 centage of cull in the main bole from the stump to the utilized top 

 and to a fixed top diameter of 8 inches for board- foot volumes and 

 h inches for cubic-foot volumes. 



The factor values were read from smoothed curves based on 

 trees from all of the study areas and are, therefore, designed to 

 apply throughout Southeast Alaska.
