150 THE THEORY AND PRACTICE OF WORKING PLANS 



or in a special file. The forest description of the entire working 

 unit should be a careful summary of the description for each 

 block.* The aim is to present a lucid picture of the forest as 

 it is in the essential sihdcal factors bearing on the plan of man- 

 agement adopted. The description must be ample reason for 

 the pro\isions of the working plan. The description is the 

 premise; the recommended management the logical deduction 

 from that premise. 



(g) Division of Area. — On the basis of the forest description, 

 the di\'ision of area should be so evidently logical as to require 

 very little special justification. However, it is well to explain 

 briefly what considerations governed in the choice 'of working 

 unit, block, compartment, and subcompartment, in so far as 

 this was not already covered in the digest of the working-plan 

 conference. Since the working unit usually has a sustained 

 yield, its adequacy from this viewpoint should be considered 

 along the broad lines already laid down. 



3. Recommendation 



The recommended management should be the logical sequel 

 of the data given under " Orientation " and " Foundation." 

 The basic considerations of object of management, of silvi- 

 cultural method of management, and of rotation are con- 

 tained in Chapter I, Section 3. This part of the working- 

 plan document should re\'iew the governing conditions which 

 determine the recommended management. These are: 

 [ ■ (a) Object of Management. — i.e., the wishes and purpose 

 of the owner (in so far as not already contained in the digest 

 of the working-plan conference). 



(b) Practical Restrictions of market, logging accessibihty, 

 fire danger, erosion danger, etc. 



(c) Silvicultural Method of Management which can best 

 fulfill the object of management with the given silvical conditions 



* A good example of such a forest description will be found in Bulletin 1 1 of 

 the N. Y. State Consen-ation Commission, " Forest Survey of a Parcel of State 

 Land," Albany, 1915.
