Lodgepole Pine and Other .Xoncommercial 

 Conifer Types 



The three lodgepole pine types cover a total area 

 of 2.1 million acres (fig. 14), little of which will 

 support commercial forests. Lodgepole pine stands 

 in this region have little or no commercial value at 

 present and can on the whole be so classified. 



Noncommercial rocky and subalpine types (38 

 and 33) total 2.3 million acres, approximately two- 

 thirds of which is in Washington where the Cascade 



Range is more rugged. Very little land of this 

 kind is privately owned. Of no value for timber 

 production, it protects the headwaters of streams 

 and has definite value for recreational use. The 

 most beautiful roads and trails in the region are in 

 the subalpine type (fig. 15). 



Deforested Lands 



Fortunately only a comparatively small portion 

 of the land is deforested — only about 1 percent as a 

 result of fire or cutting, and fire is the principal 

 cause. Deforested burns, about equally divided 

 between Oregon and Washington, are chiefly at 

 high elevations and inaccessible locations in the 

 national forests where the original forest was non- 

 commercial or of low value. Most of the non- 

 restocked cut-overs are in Oregon, where cutting 

 has been more extensive, on accessible and usually 

 good growing sites that should be restored to pro- 

 ductivity.
