MANAGEMENT PLANNING UNIT 



The development of forest areas is based on management 

 plans that provide detailed information about the volume 

 of annual cut, cutting methods, regeneration treatments, 

 road and camp locations, and other facts essential to 

 orderly management. 



Standard management plans are based on inventory data 

 gathered using photo interpretation, point sampling, and 

 computer compilation methods. The information is entered 



in stand ledgers, which also serve as a record of changes. 

 Standard plans have been prepared following the re-inven- 

 tory of Crown management units started in 1958. The essen- 

 tials of this type of planning are contained in the Manual of 

 Management Plan Requirements. 



The initial management plans, based on the inventory 

 method used prior to 1958, are retained until replaced with 

 standard plans, and form the basis for the management 

 of a large proportion of the Crown management units in 

 the Province. 



Management plans form a framework into which operat- 

 ing plans are fitted. An operating plan shows in detail the 

 stands to be cut, regenerated, and tended, and the roads to 

 be built and other improvements to be made to carry out 

 operations on the management units.
