SALVAGE CUTTINGS 



195 



The severity of the cutting depends entirely upon the pro- 

 portion of the stand occupied by the damaged trees. On this 

 basis' a salvage cutting may range in character from a thin- 

 ning to a clearcutting. 



Salvage cuttings are not made unless the material taken 

 out will at least pay the expense of the operation. Excep- 



A = Fire scars. B = Stagheaded tree. C = Canker. D = Killed by insects.

A stand in need of a salvage cutting. The injured trees are indicated by- 

 dashes. So many trees require cutting that the remaining stand will be irregu- 

 lar and open. Reproduction will be needed to fill the openings. 



tions to this statement occur when it becomes essential for the 

 safety of the surrounding forest to remove unmerchantable 

 trees attacked by insects or fungi. 



Even though the damaged material can be salvaged at a 

 profit the injuries which made the operation necessary ordi- 

 narily occasion an ultimate loss. This is true especially when 

 stands in the first half of the rotation are damaged. The 

 loss is due partly to deterioration of the injured trees before 

 being salvaged, partly to a reduction in the density of stocking, 

 with the possibihty that a portion of the area may be unpro- 

 ductive, and partly to the tutting of the injured trees before 

 they had attained the size and could furnish the products 

 desired by the owner.
