National-Forest Ownership 



The national forests, as in other parts of the West, 

 were originally created from the public domain. 

 Although they contain practically all of the inac- 

 cessible mountainous areas and noncommercial 

 forest land, they also contain vast areas of high 

 quality timberland. Alienation had not advanced 

 so rapidly prior to their creation as in the Douglas- 

 fir region. In recent years the national-forest 

 areas have increased by exchange and purchase. 



Sustained-yield principles govern the manage- 

 ment of the national forests, and cutting on each 

 operating unit is limited to the maximum specified 

 in the working plan. Administration of national- 

 forest timber sales makes adequate provision for 

 protection of growing stock and for prompt regen- 

 eration. Disposal of national-forest timber is co- 



ordinated wherever possible with private operations 

 to encourage sustained-yield practice on the part 

 of private owners. 



Actual cutting on most national forests has been 

 less than the sustained-yield capacity owing mainly 

 to lack of a market. Cutting of the more inacces- 

 sible national-forest timber will be deferred until 

 the private timber supply is diminished. Eventu- 

 ally cutting will probably be extended to all the 

 commercial timber areas of the national forests. 



The national forests contain approximately half 

 the region's forest land and saw-timber volume. 

 Approximately 737,000 acres of forest land support- 

 ing 2.6 billion board feet of saw timber is reserved 

 from cutting for one reason or another. Generally 

 speaking, the reserved timber is remote and in- 

 cludes very little ponderosa pine. A large part of it 

 is in little used species.
