6. Overstory Remo val 



This involves the application of a partial cut to two-storied stands 

 for removal of the overwood and perpetuation of the understory. 



This method is practical if the following conditions are met: 



a. The understory should consist of healthy and desirable tree 

 species for the particular site, 



b. The area must have desired stocking after logging, 



c. The understory must be younger than 80 years, and able to 

 maintain a satisfactory rate of growth after removal of the 

 overwood , 



d. If the understory is patchy, some overstory trees should be 

 left near the open areas as a seed source and protection to regain 

 full occupancy of the site by a new seedling crop, and 



e. During the overstory removal operation, care should be taken 

 to avoid unnecessary damage to the young residual stand. This 

 should be emphasized for both falling and skidding operations. 



7. Salvage Cutting 



This harvesting method is used to recover dead or dying 

 merchantable timber which may have been killed by disease, fire, old 

 age, etc. Sufficient volume of higher risk live timber may be 

 included in order to effect an economic operation. 



8. Sanitation Cutting 



All foresters should be aware of disease and insect damage and 

 designate those trees for removal. High risk trees (injured, unhealthy, 

 decadant and suppressed) should also be considered for removal. 



In addition. Champion's guide states that consideration should 

 be given to converting old growth sawtimber stands into healthy, 

 vigorous stands of less than 80 years old. Any of the previously 

 described harvesting methods may be employed. The forester should 

 again consider species composition, aspect, slope, age of the stand, 

 stand vigor, soil type and habitat type when prescribing a harvest 

 system.
