APPENDIX 53 



areas in having a brushy rather than an herbaceous undergrowth, characterized 

 by willow, alder, myrtlebrush, Ribes viscosissimum, and ninebark. This brush is 

 very dense on the first two plantations and only moderately dense in the case 

 of the third. The soil is a sandy loam containing some rock. 



56. The site upon which these five plots are located is known as block F, 

 and lies near block B on the west side of Day's Fork at an altitude of about 

 7,800 feet, 400 feet above the canyon floor. This site differs from the two pre- 

 ceding in having a moderate cover of grasses and herbs, and only scattered 

 brush. Vegetative competition is not so severe as on the other sites. 



57. This plantation is located at some distance from the others, on a west ex- 

 posure, with a gentle slope in aspen, in Mill D North Fork, at an elevation of about 

 7,800 feet. The soil is a deep dark loam, apparently fairly moist, considering the 

 aspect. Ground cover is mainly herbaceous, with a scattering of Symphoricarpos, 

 and is not very dense. 



58. This plantation is located on a fairly recent burn, still log strewn, and not 

 dominated by a closed stand of brush. It lies up hill above the area described 

 as site 54. The soil is a deep sandy rocky loam. The brushy species which 

 characterize the area are Syrnphoricar-pos, elder, mountain ash, willow, maple. 

 Elevation is 7,700 feet. 



59. This plantation is located near the aspen area described as site 55. It is 

 situated on a northeast exposure at 8,100 feet elevation on a fairly recent log- 

 strewn burn covered with an open stand of scrubby small aspen, willows, and 

 maple. The soil is a deep sandy loam. 



60. This area is near the previous one noted, but the brush is dense, con- 

 sisting of the same species noted above, aspen, willows, maple, together with 

 Ribes viscosissimum and myrtlebrush. 



61. Planted on block G,"an open grassy area occupying an old burn in the 

 spruce-fir type. The trees have all fallen and have mostly rotted away. A 

 dense sod covers the area, and this increased its density notably since the area 

 was fenced. There are a few clumps of elder and spring Grossularia. No 

 natural reproduction is coming in on this area. 



62. The site is the same as site 56, except it bears no aspen. The brush and 

 herbaceous vegetation are similar. 



63. Planted on a bench sloping northwest covered with a fair growth of sage- 

 brush, together with occasional specimens of Symphoricarpos, chokecherry, and 

 small aspen. The altitude is 7,450 feet. The sagebrush was all grubbed out on 

 part of this area prior to the planting. 



64. Planted On a bench with a very gentle slope, northwest aspect, covered 

 with aspen of somewhat varying density interspersed with a few young lodge- 

 pole pines, and such brushy species as sagebrush, Symphoricarpos, snowbrush, 

 and chokecherry. The elevation is about 7,400 feet. The first of the four plan- 

 tations is under pure aspen, and very few brushy species are present, there 

 being merely a scanty herbaceous cover. 



65. Planted in sagebrush type on a very gentle slope- with north exposure. 

 The soil is a rocky loam derived from limestone. 



66. Planted near the area just noted but in aspen cover; slope, exposure, and 

 soil are similar. 



67. No data exist in the records describing this site in detail. It is on the 

 Shingle Creek planting area, the first plantation being made by common labor, 

 the second by technically trained men. 



68. Planted on a moderately steep north exposure in fairly dense sagebrush 

 cover. The soil is a deep loam. Besides the sage, there is a light cover of grass 

 and weeds. It is near the Elbow Canyon Ranger Station at 6,500 feet elevation. 



69. Planted on a small flat where a draw enters Montpelier Canyon below 

 Elbow Ranger Station. Altitude is 6,900 feet. The slope is very gentle, with an 

 eastern exposure. The soil is a deep loam. The cover is open aspen, the ground 

 being covered with a fairly dense growth of pine grass. 



70. 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 follow- 

 ing, 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. While all three plantations 

 were located in this same general type, they were not on precisely the same sites, 

 the first being on an eastern exposure, the second and third on flats. 



71. All seven of these plantations are close together, some on a bench above 

 the brow of the hill, and some on the slope below. The area is covered with an 

 irregular stand of aspen interspersed with some lodgepole pine and Douglas fir,
