Where the property is made up of two or more, radically dif- 

 ferent types of woods so that each of these types requires special 

 treatment, then the forest is divided into two or more Working;' Sec- 

 tions. The following illustrates this : 



Area : 20,000 acres. 



Location : A'lichigan Pinery district. 



Types: Hardwood and Hemlock 35% or 7,000 acres 



Pinery proper 50% or 10,000 acres 



Tamarack and Cedar S.wamp. ... 15% or 3,000 acres 



Figure 6. Township of Typical Lake Region Pinery Lands with three 

 types of lands and three permanent types of forest ; Pinery lands with pure 

 and mixed stands of Pine ; Hardwood and Hemlock forests on slightly 

 heavier soils ; and swamp lands stocked with Tamarack, Cedar, mixed with 

 Spruce, Pine, and Hardwoods in better drained spots. These three types call 

 for different species, silvicultural methods, and rotation and therefore demand 

 three separate Plans, each type forming one Working Section. 



From the diagram. Fig. 6, it is apparent that the swamp forests 

 are in several pieces of irregular shape, following drainage lines. 

 The plan of Silviculture here proposes to treat Pine by the Clear 

 Cut and plant method. Hardwoods as Selection forest, and swamj)
