1 NS = nonsignificant (P < 0.05) 

 NT = not tested 



different letters indicate significant differences (P < 



0.05) 



indicating that stands with high CCF's had poor diam- 

 eter growth response. Habitat type was also asso- 

 ciated with the response of western redcedar to release. 

 Trees growing on the THPL/PAMY habitat type had the 

 best response, which was significantly different from 



that on the other three habitat types. There were no 

 significant differences among the diameter growth 

 responses of trees on the other three habitat types 

 (table 4).
