Silvicxjltube: 



Silviculture is the art of caring for forests, 

 and therefore the backbone of forestry. It 

 is based upon Silvics, which is the knowledge 

 of the habits or behavior of trees in their 

 relations to light, heat, and moisture, to the 

 air and soil, and to each other. It is the facts 

 embraced in Silvics which explain the com- 

 position, character, and form of the forest; 

 the success or failure of tree species in 

 competition with each other ; the distribution 

 of trees and of forests; the development of 

 each tree in height, diameter, and volume; 

 its form and length of life; the methods of 

 its reproduction; and the effect of all these 

 upon the nature and the evolution of the city 

 of trees, and upon forest types and their life 

 histories.
