CHAPTEE VI. 



THE ORGANISATION OF THE WORKING PLAN. 



THE preliminary working plan report is prepared after consulta- 

 tion with the local executive staff, either by the Head of the 

 working plans branch or under his orders. This report deals in 

 considerable detail with the past system of management and its 

 results, and that proposed for the future. Where any great 

 changes are indicated in the management this report will deal 

 with the division into working circles, the silvicultural system to 

 be adopted, and the method of calculating the yield. It will set out 

 in such detail as i3 necessary the framework of the revised plan, 

 leaving the details to be filled in by the working plan officer. 

 The preliminary report is forwarded to the Chief Conservator for 

 his approval of the system of management outlined. 



We may therefore in this place consider the different 

 treatments to which a crop of trees may be subjected and their 

 advantages and disadvantages ; when they should be adopted and 

 when avoided. The three main methods 



Eegular or Uniform High forest, 



Irregular High forest, 



Coppice, 



and their component silvicultural systems will be discussed. 

 The details of each silvicultural system as employed in actual 

 practice are dealt with in subsequent chapters. In determining 

 the method of treatment to be adopted it is necessary to consider 

 the cultural requirements of the species, the demands of the 

 locality, or distant markets, for forest products, and the finan- 

 cial result likely to be obtained. The cultural requirements of 

 the species are paramount ; conifers can only be managed as high 

 forest and some broad leaved species will not coppice. In the case
