Appendix 



To use the curves in the Appendix, find the graph for the 

 desired CCF and d/D. Move along the curve for the appropriate 

 site index until the height of the curve corresponds to present 

 d.b.h. Then move one decade interval to the right* to find diam- 

 eter one decade hence. Note that the horizontal axes are 

 labeled "decade intervals" to indicate a discontinuity-over-time 

 of the curve relationships shown. This has been done to prevent 

 the graphs from being mistakenly interpreted as illustrating 

 diameter growth development over age (or longer intervals of' 

 time than 10 years) . 



Users are reminded that these curves utilize site index 

 values based on a 100-year index. The curves are for an average 

 elevation of 6,000 feet above mean sea level. With regard to 

 the effect on diameter increment, an increase of 1,000 feet in 

 elevation would correspond to a decrease of about 8 percent 

 in site index.
