12 THE NATIONAL FOREST MANUAL. 



In the completed plan the data secured under each 

 qiSredii^aJhpfa"" topic will be summarized and the conclusions stated. 

 The following points are of special importance: 



1. Silvicultural systems based on the most reliable silvical data 

 available, and upon careful observations on the part of the working- 

 plans officer. 



2. A carefully drawn set of marking principles designed to put into 

 effect the silvicultural s}^s terns recommended. 



3. The maximum annual cut to be allowed during the ensuing 10 

 or 15 years, and the approximate cuts for each period of the rotation. 



4. The order in which the important bodies of merchantable tim- 

 ber should be sold. 



5. The order in which areas needing artificial restocking should be 

 sowed or planted, and the acreage to be covered during each year 

 of the period for which detailed recommendations are made. 



Under "Grazing," technical reconnaissance and special studies 



Grazing should be conducted, following the general ground 



covered under preliminary plans but with more 



detail and greater exactness, with such additions as the needs of the 



Forest warrant. Since detailed grazing reconnaissance is somewhat 



technical in nature, it should be directed as far as practicable by 



grazing experts. 



The permanent improvement plan for the Forest should be con- 

 sidered and developed as far as may be practicable 

 pavements. en " in connection- with the intensive timber estimates 

 and other investigations conducted by working-plan 

 parties. 



The protection plan for the Forest should be furnished to parties 

 Forest protection conducting working-plan investigations, and recom- 

 mendations for its modification or extension, as far 

 as may be found advisable, submitted by them to the supervisor. 

 Working-plan parties should familiarize themselves with the por- 

 tion of the preliminary plan dealing with uses of 

 iand es f Forest Forest land. Additional data should be secured as far 

 as practicable in connection with timber estimates and 

 other intensive field work. Recommended changes or improvements 

 should be submitted to the supervisor. 



ANNUAL PLANS. 



The annual reports, estimates, and recommendations submitted 

 on the various lines of Forest work should be based upon the pre- 

 liminary or working plan for the Forest and should refer specifically 

 to the portions of the plan dealing with the subject in question. 

 They should show how far it is feasible to apply the plan to the work 

 of the Forest during the current or ensuing year, the specific action 

 proposed to put its provisions into effect, and the changes which 

 appear advisable. 



The annual allotment and appropriation estimates will be in- 

 cluded, with such modifications as are necessary, 

 tration r . al " in the portion of the plan dealing with general 



administration.
