All stands under code 40 possess the following characteristics: 



1. Fully stocked Douglas-fir, western larch, or ponderosa pine sap- 

 lings, poles, or small sawtimber. 



2. Growth rates at or near full potential. 



3. Poor crown ratios (less than 30%). 



4. No unmanageable insect or disease problems. 



The problem in this situation is that the compiled data fails to explain 

 why a stand would have poor crown ratios, but also good growth rates during 

 the last ten (10) years. Have crowns recently become suppressed from 

 competition? In this case, the next ten years' growth might be much lower. 

 Or, has this stand been released during the last ten years? In this case, 

 the crown ratios may be improving, even though they are presently unaccept- 

 able. 



Because the data summary does not answer the above questions, the 

 treatment opportunities are not logically defined for such a stand. 



Possible combinations: None
