Camp Steeley Nursery 



Last fall a ranger nursery was established at Camp Steeley in the Pocatello National 

 Forest, Idaho. The seed was sown this spring, and the species used were Douglas 

 fir, western yellow pine, Scotch pine, and lodgepole pine. There is a good oppor- 

 tunity for enlarging the seed beds, and Supervisor Wrensted has made specific recom- 

 mendations that the nursery be increased to four times its present capacity, making 

 a total seed bed area of two-fifths of an acre. The increased area is needed in order 

 to secure an adequate basis for extensive forest planting on city watersheds. 



The nursery site is favorably situated, since seedlings can readily be shipped to 

 other National Forests in southern Idaho. 



Frye Canyon Nursery 



A ranger nursery was established in the Frye Canyon, in the Mount Graham 

 National Forest, about 12 miles southwest of Safford, Ariz. It is well situated at an 

 altitude of about 6,700 feet. A portion of this nursery was sown with yellow pine 

 and Arizona cypress seed last season, and a recent inspection shows that it now con- 

 tains 18,000 western yellow pine seedlings. The beds that were not sown last year 

 have been seeded this spring with western yellow pine and Arizona w r hite pine col- 

 lected in Arizona and sugar pine and Coulter pine collected in southern California. 

 It is believed that these two southern California species will prove of considerable 

 value for planting in the Mount Graham National Forest. 



In order to determine the most desirable planting sites before the stock from the 

 Frye Canyon Nursery is of sufficient size for planting, a small quantity of seedlings
