244 THE THEORY AND PRACTICE OF WORKING PLANS 



The location of all uses which have been granted should be 

 recorded on a base map of the forest. Any information secured 

 as to tracts desirable for particular uses should be similarly 

 recorded, especially reservoir and dam sites, as part of the 

 inventory of the resources of the forest. 



The water-power possibihties of the forest, including 

 stream measurements and the collection of cost and market 

 data. 



All administrative sites should be shown on the improve- 

 ment map of the forest. Sufficient additional data will be 

 recorded to show in concrete form the system of administra- 

 tive sites devised for the forest, including patrol and look-out 

 stations, nurseries, and sites required for logging facilities, and 

 other uses in connection with the sale of timber. 



WORKING PLANS 



A working plan is simply an extension and development of 

 the preliminary plan, based upon more exact data. Such a 

 plan should ultimately be prepared for every forest as the need 

 for a more systematic basis of management becomes urgent. 

 Reconnaissance work should, except in unusual cases, result 

 in working plans. 



Working plans will be prepared first on forest where the 

 demand for timber is great as compared with the supply, and 

 where large quantities of timber are evidently mature and it is 

 reasonably certain that sales can be made if the proper data 

 are secured. It may be advisable to prepare special working 

 plans for forests on which large areas are in need of reforesta- 

 tion. Special grazing working plans may be prepared for forests 

 where the use of forage resources is of importance. Special 

 problems in any other phase of service work demanding careful 

 study may require the preparation of working plans. Where 

 conditions on a forest differ widely, it may be advisable to cover 

 only the part of a forest to which the special administrative 

 urgency applies. 



Each working plan will outline the general management of
