with a ground cover of pine grass. The soil is a light sandy loam. Rodent 

 damage has been severe on all these plots, especially those on the bench. 



72. Planted on a small grassy opening between broken stands of aspen, on a 

 west exposure with a gentle slope. The soil is a gravelly sandy loam, apparently 

 fairly well watered. The ground cover is largely pine grass and Carex of moderate 

 density. A few aspen root suckers are coming up on the area, but are too scat- 

 tered and small to cast appreciable shade. Altitude 6,900 feet. 



73. All three of the plantations in aspen are upon the same general moderate 

 slope of a westerh^ aspect. The first plantation is at a somewhat higher elevation 

 than the next two in the list, being at 6,900 feet in a small area of aspen adjacent 

 to the opening described as site 72 above. The aspen is moderately dense, 

 ground cover is scant. The lower area is in smaller, denser aspen with a rather 

 dense ground cover of pine grass. 



74. Planted in a recent Douglas fir burn on a moderate slope with a north- 

 westerly exposure. The soil is a sandy loam. The ground cover is of moderate 

 density, consisting of many species of herbs, grasses, and shrubs. Natural 

 lodgepole pine reproduction is coming in on the area. The first plantation was 

 made by common labor, the second by skilled technical labor. 



75. Plantation made on block O in a site similar to that mentioned in the 

 description of site 35, and about 200 yards distant. The area is on the edge 

 of the aspen type, hah the plantation being in aspen and half in brush immediately 

 to the north and shaded considerably from direct sun by the aspen stand. 



76. Planted on block O on the top of a flat ridge at 8,100 feet elevation, in 

 an area covered with aspen of very poor quality with a nearly suppressed under- 

 story of manzanita. There is an active invasion of Douglas fir and white fir on 

 the area. The soil is unusually sandy for the Ephraim Canyon drainage, similar 

 to the manzanita site adjoining on which Douglas fir and lodgepole pine were 

 planted. It consists of a light brown very fine sandy loam underlain with a 

 yellowish gravelly to stony very fine sandy loam which grades into a grayish 

 clay at 15 to 20 inches. 



77. This site is only about 50 yards from the preceding and adjoins the area 

 mentioned as site 35. It is located in a small natural opening in the aspen which 

 is virtually barren (overgrazed), soil conditions are like the near-by areas. 



78. In aspen of variable density, averaging intermediate on a moderate slope, 

 east exposure at 8,100 feet elevation. The soil is a sandy clay loam. The 

 ground cover is thin, composed of grasses and herbs. 



79. In a patch of oak brush of moderate density, on a gentle slope, east 

 exposure at 8,100 feet elevation. The soil is a deep-black clayey, sandy loam. 

 The ground cover is of scattered grasses and herbs. 



80. All of these plantations were made upon the same general site, an old 

 burn in the spruce-fir type. The area came up to a broken, open stand of aspen 

 after the fire, the openings being covered with sage and weeds. These planta- 

 tions were made in long single lines and traversed some aspen cover and some 

 sagebrush openings. .Records were kept separately on the two sites. In general, 

 the area is characterized by moderate slopes with north and northeast exposures. 

 The soil is a rich sandy loam. The aspen cover is light, and in the openings the 

 sagebrush is small and scattered, being intermixed with many herbaceous species. 

 The elevation is 7,400 feet, rather low for spruce. 



81. Planted on Area A to the east of the Cottonwood Nursery at an elevation 

 of 7,600 feet, not much above the level of the valley floor. This location is 

 characterized by a rich, moist loamy soil and dense aspen cover. The ground 

 is open at planting time, but later in the season it becomes a jungle of elder, 

 nettles, Rudbeckia, Thalictrum, and Washingtonia, which added to the Sym- 

 phoricarpos on the ground, makes a very dense shade and strong root competition. 



82. Planted on Block F, an area covered with aspen of moderate density 

 upon a northeast exposure with moderate slope at an elevation of 7,800 feet, 

 400 feet above the level of the canyon floor. It has a moderate cover of grasses 

 and herbs. 



83. Planted in aspen of moderate density, intermingled with scattering 

 alpine firs, upon a gentle slope, north exposure. Altitude is 7,300 feet, scarcely 

 above the canyon floor level. The ground cover is moderate, consisting of such 

 brushy species as snowbrnsh, Si/mphoricarpos, myrtlebrwsh, elder, together with 

 grasses and herbs. The soil is a sandy, silty loam. 



84. Planted in thin scrubby aspen cover i^\ Shingle Creek. The first was 

 planted by skilled technical labor and the second by common labor. These two 

 plantations are in rocky, clay Loam soil on a northwest aspect. Ground cover 

 consists mainly of such shrubs as rose, Symphoricarpos, chokechcrry, and nine-
