42. Planted on block O. There is considerable deep shade from scattered 

 white firs on this site, and around these trees a deep conifer duff. 



43. Planted near block Q in oak brush on a steep north slope at 7,400 feet 

 elevation. Soon after planting a road was cut through the area. The figures 

 on survival the fourth year are from that portion of the area which was not 

 affected by the road. The site is similar to the following. 



44. On block Q in moderately dense oak brush on a north exposure, slope 

 40 per cent, 7,400 feet elevation, soil composed of 3 to 4 inches of humus layer 

 over light-brown clay loam, clay, and gravelly or stony clay (limestone) . 



45. The plantations in aspen in Big Cottonwood "Canyon were not all on 

 one compact area, but they were not far separated. All were at an elevation 

 of about 7,500 feet to 7,800 feet, and all were on north to northeast exposures 

 with steep slopes. The aspen is fairly dense, of small size (4 to 6 inches in diam- 

 eter), the ground cover is scanty, herbaceous, or grassy. On the forest area 

 listed in Big Cottonwood Canyon, there is a rather dense growth in midsummer 

 of grass, Rudbeckia, and some shrubs. 



46. This area adjoins one of the aspen areas. The grass and herbaceous cover 

 is dense. Otherwise the site is similar to the previous one. 



47. 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 Sevier National Forest seed, the 

 second from Salmon National Forest seed. 



48. This plantation is located in a small patch of moderately dense, rather 

 scrubby aspen adjacent to a sagebrush flat. The slope is gentle, aspect north, 

 elevation about 7,000 feet. There is a light ground cover of grass and weeds. 

 The soil is a light gravelly loam. 



49. The 2-1 and 2 1/2-0 stock used on three of these plantations came from the 

 Gallinas Nursery (New Mexico) and received different amounts of shade in the 

 transplant beds. These plantations are all in a rather scrubby aspen type, 

 adjoining a large sagebrush basin, slopes are gentle, aspect east to northeast. 

 The ground cover is moderate, grasses and herbs. The soil is a brown silty loam, 

 rather heavy. The last two plantations on this site lie side by side at some little 

 distance from the rest, and on more moist land. 



50. These plantations are all in the aspen type, those near the bench being 

 just over the brow of the hill from those on the slope. The aspen is in a rather 

 broken stand, with a ground cover of pine grass and herbs. Ground squirrels or 

 gophers have done great damage on the bench. There is a very scattered natural 

 growth of Douglas fir and lodgepole pine on the areas, especially upon the slopes. 



51. A site in dense young aspen near the lower limit of its growth in the hills 

 fringing the Teton Valley. The soil is a sandy loam. There is a dense ground 

 cover of pine grass (Calamagrostis rubescens) . Exposure west, slope moderate. 



52. Planted on block P at 9,800 feet elevation in the spruce-fir zone under 

 dense and medium aspen and in the open adjoining. The site is on a flat bench 

 protected by a high ridge to the south and west. The soil is a light-brown clay 

 loam underlain by yellowish or grayish clay. At the time of planting it was dry, 

 hard, and cloddy in the aspen, but fresh" and moist in the open, owing to the 

 location of snowdrifts on the area. 



53. Planted on block S, Engelmann spruce burn not restocking and still covered 

 with much down timber. The exposure is north, slope 25 per cent, elevation 

 9,900 feet. The soil is a rich mellow loam of limestone origin. The area is 

 heavily grazed by sheep and cattle and the trees are planted close to stumps and 

 down timber. This area is not in the Ephraim Canyon drainage, but is opposite 

 its head in Seeley Creek (Colorado River drainage). 



54. All these aspen sites are similar in being located in aspen cover of moderate 

 density on northeast exposures. They arc scattered upon three areas, however, 

 which vary in minor ways. The first Vas located on block A to the east of the 

 Cottonwood Nurser} 7- site, at an elevation of 7,600 feet, not much above the level 

 of the valley floor. This location is characterized by a rich moist loam 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 Was/n'ngtonia, 

 which, added to the Symphoridarpos on the ground makes a very dense shade 

 and strong root competition. 



55. These plantations are on block Bon the hill immediately to the southwest 

 of the Cottonwood Nursery across Day's Fork at an altitude of about S.100 foot, 

 some 600 feet above the canyon floor. They arc different from the preceding
