MANAGEMENT PLANS THE NATIONAL FOKESTS

Advantages of slow cutting. — (a) Removes all of the mature timber and most 

 of the thrifty mature. (6) Provides for a greater growth on remaining stand 

 because of more complete release, (c) Simplifies marking, {d) Insures a 

 profitable operation at present. 



Disadvantages of slow cutting. — (a) Makes a reduction in the second cut of 

 from 40 to 45 per cent. 



EEGULATIGN OF THE CUT 



Because of the maturity of the stand annual growth will not greatly exceed 

 annual loss from old age, insects, windfall, etc. Determination of the annual 

 cut by methods involving a detailed knowledge of increment was, therefore, 

 not considered necessary. 



In arriving at the annual cut the total amount to be cut, 787,646,000 board 

 feet, was divided by the length of the cutting cycle, 50 years, giving an annual 

 cut of 16,000,000 board feet. 



FORECAST OF SECOND CUT 



Basis : 



23,732 acres, site class II, 



20,000 board feet predicted stand per acre at end of 50 years. 



474,640,000 board feet. Total stand at end of 50 years. 



379,712,000 board feet stand to be removed during second cutting cycle. 



379,712,000 divided by 50 equals 7,594,000 board feet or annual cut. 



A cut of 7,500,000 feet from Site II, plus whatever excess may accumulate 

 during the first cutting cycle, together with a small cut from Site III, should 

 give a total second cut of from 8,000,000 to 9,000,000 feet per year. 



In 50 years, with closer utilization and with the increase in the value of 

 lumber, this should make a profitable operation.
