after release when compared to trees growing on soils 

 having smaller amounts of these nutrients. 



Tree characteristics were also associated with the 

 release response of western redcedar. The larger the 

 tree diameter at the time of release the greater was its 

 growth after release. Also, the younger the tree at the 

 time of release the better its growth after release. 



Foliage color was associated with tree growth and 

 nutrient content of the foliage. Trees with green-yellow 

 foliage had greater growth rates than trees with 

 greenish-yellow foliage. Discriminant analysis 

 simultaneously detected differences in mean nutrient 

 contents for 12 different nutrients in the foliage of 

 release'd western redcedar. 



The results of this study emphasize the importance of 

 site, stand, and tree characteristics in the amount of 

 response western redcedar trees have after they' are 

 released from overhead and surrounding competition. 

 The species will respond favorably to release, 

 depending on tree size, tree age, habitat type, slope, 

 aspect, and soil nutrient content.
