APPENDIX 51 



27. These plots are located in an extensive open flat which originally bore 

 a heavy sagebrush cover. This was burned off in 1915 and in the two years 

 following plantations were made, at which time the areas were covered with a 

 dense growth of wild geranium. After 1917 the sagebrush began to come back 

 little by little. The soil is a rather heavy brown silt loam The third, fourth, 

 fifth, and sixth plantations listed on this site are tests of classes of stock planted 

 side by side. Of the two plantations of 2-0 stock planted in April, 1916, which 

 show 64 per cent and«66 per cent survival in the first year, the first was made 

 with unskilled labor, and the second with technical labor on the same site. The 

 2-1 stock on the first plantation listed was from the Monument Nursery 

 (Colorado). The second lot was from the Beaver Creek Nursery (Utah). Of 

 these two plantations the first was on a slight southwest and the second on a 

 northeast exposure. 



28. This area is in scrubby aspen adjoining the sagebrush flat above described. 



29. A northeastern aspect with moderate slope characterized by bitterbrush 

 and snowberry. The soil is a heavy brown silty loam. 



30. These plots are on a steep slope with a northeast aspect bearing a dense 

 thrifty growth of snowbrush, serviceberry, myrtle brush, chokecherry, rose, and 

 bitterbrush. The soil is coarser than on the sage and permanent brush types 

 and is more favorable to plant growth. Many mesophytic herbs are found 

 among the clumps of brush. 



31. These plots are adjacent, one set on a northeast exposure, the other upon 

 a nearly flat bench. The first planting on each site is by the center-hole method, 

 the second by the slit method. The soil is a brown loam, well suited to the 

 latter method. The area is covered with small aspen, intermixed with a few 

 lodgepole pines and Douglas fir. There is a fair ground cover of pine grass and 

 herbs. Ground squirrels and gophers did much damage. 



32. Planted in block B, a flat covered with a mature stand of large aspen at 

 8,700 feet elevation. The aspen has been thinned to give 5 degrees of densitv 

 having light values of 0.20, 0.30, 0.45, 0.60, and 1.00 (Clements photometer). 

 The soil is a very fine sandy to compact loam. The damage from gophers has 

 always been excessive here. 



33. Planted on block K under uneven cover of young aspen following a burn 

 about 15 years before. Exposure north, slope 15 per cent, elevation 9,200 feet, 

 situated near the foot of a long slope. Soil is a light-brownish very fine sandy 

 loam 8 inches deep over a stiff clay. 



34. Planted on block 3. Conditions of site same as on block A, except 

 elevation is somewhat higher, 7,800 feet, and the ground is covered fairly densely 

 with myrtlebrush (Pachystima myrsinites). 



35. Planted en block O. Conditions are virtually the same as on block C 

 (site 16), which lies about one-eighth mile south, except that rabbit damage 

 has been exceptionally severe. 



36. Plantation made on block D, in a hollow covered with large dense aspen 

 of first quality. Exposure south, nearly flat, elevation 8,500 feet. Soil is a 

 dark-grayish clay moderately friable when dry, 1 to 3 inches of forest mold on 

 the surface. The forest floor is quite brushy and there is little light. 



37. Planted on block G, an old burn in the spruce-fir type on a steep north 

 exposure (slope 50 per cent), at an elevation of 9,500 feet. The area still shows 

 some down timber; it is heavily sodded except in the vicinity of gooseberry and 

 elder bushes. Snow is heavy and lies late in the spring upon this site. 



38. Planted on block M, located on a south exposure at 8,700 feet elevation, 

 slope 25 per cent. The plantation on this area is located half in the open and 

 half in light scrubby aspen cover. The open portion of the area is an overgrazed 

 barren stony area, a very severe site. Soil under aspen somewhat better. Fig- 

 ures given show average survival on whole plot, although nearly all the trees 

 planted in the open half died within a year. 



39. Planted on block O, on a fiat ridgetop having a slight slope to the north- 

 west at 8,100 feet elevation. The site is a small patch of dense sagebrush about 

 2 feet tall, nearly surrounded by aspen type. Soil is a brown silt loam grading 

 into a light-brown compact clay loam. 



40. Planted on block N at 7,500 feet elevation on an area covered with sage- 

 brush and with some oak in mixture. The area is nearly flat, having a slight 

 slope of 5 per cent to the west. The soil is a dark-gray, silty clay loam succeeded 

 by a light-brown clay at the depth of a few inches. 



41. Planted on block O over a flat ridgetop at 8,100 feet elevation which has 

 a virtually complete cover of manzanita brush 2 to 3 feet high. The soil is a 

 light-brown very fine sandy loam underlain by a very stony (sandstone) soil 

 of the same composition. The soil is shallow,
