14 Forest Management 



CHAPTER II— SUBDIVISIONS OF A FOREST 



The subdivision of a forest into minor units of management is based 

 on local conditions and on local needs. 

 A large forest is usually subdivided into 

 Working circles (J VIII). 

 Working sections (If IX). 

 Compartments and blocks (1[ X). 



PARAGRAPH VIII. 



WORKING CIRCLES. 



Under "working circles" we understand, after Schlich, that forest 

 area owned by one person or company which is much under the pro- 

 vision of one and the same principal working plan. 



PARAGRAPH IX. 



WORKING SECTIONS. 



In large working circles, the economic conditions are frequently 

 such as not to allow of uniting all woods under one cutting plan. 

 Woods growing under more or less equal conditions and exhibiting 

 equal silvics are allotted to distinct working sections, to be dealt with 

 independently from all others. A working section should comprise 

 woods 'of all ages and classes, and should consist of several cutting 

 series. There is no need for the working section to cover a coherent 

 area. For each working section in 'Europe, the financial possibility is 

 ascertained separately. The following moments may necessitate the 

 formation of a working section: — 



1. Different species. 



2. Different silvicultural requirements. 



3. Different rotation. 



4. Different laws. 



5. Different means of transportation. 



6. Different locality. 



A large number of working sections complicates forest adminis- 

 tration. 



PARAGRAPH X. 



COMPARTMENTS AND BLOCKS. 



The leading foresters do not agree with regard to a proper defini- 

 tion of the term "compartment." For the majority of foresters, a 

 compartment is a "unit of silvicultural treatment." The compartment 

 may contain sub-compartments consisting of smaller or larger groups 

 which, to speak with the advocates of that definition, should be elim-
