CHAPTER III. 



SILVICULTURAL CHARACTERISTICS OF THE IMPORTANT 

 NEW ENGLAND TREES. 



In the first chapter the relation of climatic influences, such as 

 soil, light, etc., to tree growth has been traced and the kinds of 

 forests to be dealt with have been described. The differences 

 existing between forests are due to the trees composing them, 

 and the presence of these in turn is due to the natural conditions 

 previously mentioned. Through the centuries of its evolution 

 each tree species, as each animal species, has acquired certain 

 definite characteristics which the forester calls silvicultural to 

 distinguish them from the botanical characteristics by which a 

 species is identified. Scientific forest management must be 

 based on an accurate knowledge of these characteristics of the 

 different tree species. 



The most important silvicultural characteristics of trees, which 

 it is the purpose of this chapter to describe, are the following: 



(a) Range and distribution. 



(b) Requirements as to soil, light, and moisture. 



(c) Rate of growth and longevity. 



{d) Seed production and abihty to reproduce by seed and 



sprouts. 

 (e) LiabiUty to damage by fire, insects, fungi, etc. 

 (y) Purposes for which used. 



White Pine (Pin us strohiis). 



The white pine extends from Newfoundland and southern 

 Labrador to western Minnesota and Manitoba. It reaches its 

 southern hmit in central Illinois, Indiana, and the southern 

 Appalachians, where it is found as far south as northern Georgia
