Forest Management IS 



inated by purification of the compartments. Others maintain that the 

 compartment should designate merely a geographical unit of the forest 

 used to describe, in instructions, reports and records, the exact locality 

 at which a certain act is to be or has been performed. 



The boundary lines of geographic compartments should be natural 

 lines (ridges, creeks and slopes) as much as possible, and not artificial 

 lines (survey lanes and roads). The size of the compartment depends 

 entirely on local economic conditions. High timber prices and inten- 

 sive management invite the formation of small compartments. 



Several adjoining compartments are allotted to a "block;" for in- 

 stance, the compartments on a certain mountain or beyond a certain 

 creek. In some cases, each block has a separate series^ of compartment 

 numbers, each series 'beginning with "one." A block may be composed 

 of compartments belonging to different working sections. 



Under extensive management, a "block might be formed by the area 

 drained by an entire river system; and the compartments composing it 

 might be designated by the names of the creeks traversing them. 



CHAPTER III— WORKING PLAN REPORTS 



The term "working plan" is a misnomer. The "working plan" is a 

 report more on facts than on proposed schemes. 



The meaning of the term is somewhat indistinct. It might repre- 

 sent one or the other of the three following statements: 



1. The chief (principal) working plan, extending over a large num- 

 ber of years (a whole rotation, or the time of installation). 



2. The periodic working plan, extending over lo, 20 or 24 years 

 usually. 



3. The annual working plan, forming a mere annual budget. 



In many cases, the principal working plan is simultaneously used 

 as a periodic working plan. 



PARAGRAPH XL 



THE CHIEF WORKING PLAN. 



The chief working plan is called by Schlich. more properly, "chief 

 working plan report," and contains the following three parts: 



1. A statement of facts based on stock taking. 



2. The desire of the owner regarding the purpose of forest man- 

 agement. 



3. The plan proper, containing the forester's advice as submitted 

 to the owner, discussed with the owner and approved by the owner. 



The plan proper is, usually, a compromise between owner and for- 

 ester.
