Utah and Southern Idaho. 



Western yellow, pine in Utah: (1) Burned-over areas in the natural 

 yellow-pine types; (2) areas covered with brush, mainly of oak, 

 maple, and service berry; (3) areas covered with open stands of 

 scrubby aspen; (4) sagebrush areas. 



Western yellow pine in southern Idaho: (1) Those sites produc- 

 ing yellow pine naturally; (2) brush areas within the limits of 

 yellow pine and adjoining stands of that species; (3) open grassy 

 areas in the neighborhood of timber stands. 



Douglas fir: (1) Burns within the fir type; (2) sites covered with 

 aspen of moderate density ; (3) burns in the Engelmann spruce type; 

 (4) areas covered with brush of oak, maple, service berry, cherry, 

 and other deciduous species; (5) open grass land and mountain 

 meadows. The planting of this species naturally centers mainly 

 around the aspen type, particularly in Utah. The last two sites are 

 not considered favorably for planting at present. 



Engelmann spruce: (1) Burned-over, nonrestocking Engelmann 

 spruce and balsam-fir cuttings; (2) the denser and better stands of 

 aspen occurring at high altitudes; (3) lodgepole-pine burns. 



Lodgepole pine: (1) Lodgepole-pine burns which are nonrestock- 

 ing; (2) nonrestocking Engelmann-spruce* burns ; (3) aspen-covered 

 areas at higher altitudes. This species is not thought suitable for 

 planting on brush areas nor on open grassy land where sheltering 

 objects are missing. 



California. 



Planting has not yet progressed far enough to warrant a thorough 

 and final classification of the sites. It has been thoroughly demon- 

 strated, however, that sowing is a failure throughout the State and 

 that planting can not be undertaken with any degree of success in 

 the foothill region of southern California. At higher elevations in 

 southern California, within the timbered belt, western yellow and 

 Jeffrey pine are being grown successfully on open land free from 

 rodents. The typical planting sites in this region, however, are 

 covered with heavy brush frequented by rodents. So far the depre- 

 dations of these animals have not been successfully controlled, and 

 from present indications these depredations can not be controlled at 

 a reasonable cost. 



The planting of western yellow pine in the brush fields of northern 

 California gives promise of very good success, and it is thought that 

 white fir and incense cedar will also do well there. Climatic condi- 

 tions during the growing season are very variable in this State and 

 influence the degree of success in planting to a large extent. Long
