50 APPENDIX 



13. Planted near block Q at 7,500 feet elevation on a west exposure, about 

 25 per cent slope. The ground cover consists of a mixture of serviceberry and 

 oak, otherwise the site is similar to site 4. 



14. Planted on block H, a Douglas fir burn on a north exposure (40 per cent 

 slope) at 8,300 feet elevation, on a site where there was originally a great deal of 

 alpine fir in admixture with the Douglas fir. The ground cover now consists 

 chiefly of raspberry and bromegrass with some brushy species. The soil is a 

 thin, light-brown, very fine sandy loam resting upon sandstone. 



15. Planted on block A, under dense aspen cover at its lower limit (7,600 feet 

 elevation). Exposure west, slope slight. The soil is a dark-brown compact 

 clay, becoming lighter downward. In 1916 half of this area was severely thinned, 

 after which a second planting was made. The results given are the averages of 

 the original and thinned halves of the block. 



16. Planted on block C, an area covered with aspen of medium density at an 

 elevation of 8,300 feet. The exposure is west, the slope 6 per cent. The soil is 

 a light brown very sandy loam grading into stony clay. 



17. Planted on block R under varying degrees of aspen cover obtained by 

 thinning a stand which was originally verv dense. The light intensities secured 

 by the thinning are: 0.08, 0.20, 0.28, 0.39, 1.00 (Clements photometer). The 

 lower edge of the aspen zone, exposure north, slope 15 per cent (average) ranging 

 from almost flat to 25 per cent. The soil is a brown moderately compact clay 

 becoming lighter in color with depth. An area adjoining the aspen is also in- 

 cluded in this block. It is characterized by snowberry cover, with virtually 

 barren areas between the bushes. The soil is a sterile, brownish, crumbly 

 calcareous clay. 



18. Planted on block F, an old Douglas fir burn now thickly covered with 

 many species of low brush. Exposure north, slope 50 per cent, elevation 8,300 

 feet. The soil is light-brown, very sandy, clay loam beneath which is a yellow- 

 brown silty or very fine sandy clay. 



19. This plantation was made in oak brush on what was known as the "Casto 

 Ranch area." The soil is a brown, fine sandy loam, rather lighter in texture 

 than on similar sites in Ephraim Canyon. The brush is moderately open and 

 the trees stood between the clumps rather than beneath the canopy of the 

 brush. 



20. This plantation was made in a mixed brush tj^pe at about 6,800 feet ele- 

 vation. Survival was different on open areas and those covered with sagebrush, 

 and the records on these two sites have been kept separate. The soil is a fine 

 sandy loam. 



21. This site is upon a south slope at approximately 7,400 feet elevation in 

 a mixed brush type composed of low, open growths of scrub oak, together with 

 sagebrush, snowbrush, serviceberry, chokecheny, elderberry, and other shrubs. 

 All the plantations except the eighth listed are directly north of the old 

 Cottonwood Nursery site, the one exception being about 1 mile farther 

 down the canyon. The soil is fairly light, rocky, probably fairly well watered 

 at some depth by subterranean seepage, as many rather mesophytic species are 

 found there such as aspen, elderberry, and chokeberry. 



22. The temporary brush site lies on a Douglas fir burn, and is covered 

 mainly by chokecherry, serviceberry, snowberry, and ninebark. This site, al- 

 though too severe for the successful planting of Douglas fir, appears favorable 

 for western yellow pine. 



23. Located on a gentle northwest slope in scattering scrubby oak brush mixed 

 with some chokecherry and Symphoricarpos. Soil is a rockv, gravelly loam. 

 Altitude about 7,500 feet. 



24. Located near the previous area on a similar gentle northwest slope. The 

 original vegetation of sagebrush was grubbed out, leaving nothing but a few 

 scattering stems of chokecherry, Symphoricarpos, and a few plants of Carer. 

 The soil is a gravelly loam. 



25. Adjacent to the previous plot; similar in all respects, except that it bears 

 a fairly dense stand of sagebrush. 



26. These plots are located in dense oak brush which does not grow very 

 tall. The area probably once bore an open stand of Douglas fir, together with 

 oak brush. Fires following logging 50 years or so ago killed out the Douglas 

 fir. There is an exceptionally rank growth of other brushy and herbaceous 

 species with the oak. Rabbit damage on these plots has been considerable. 

 The first plantation listed was planted with stock from what was then the Sevier 

 National Forest seed, the second from Salmon National Forest seed.
