Plate 46. SARGENT MOUNTAIN: 1919 - 1943 - 1999 Grazing was extremely heavy in 1919 and had been for many years, judging by the browsing high-line on the oak brush (Quercus sp.) and serviceberry (Amelanchier alnifolia) on the hillside (left-center of photo). The range apparently had improved by 1943; the oak brush was no longer heavily browsed and a dense stand of sagebrush (Artemisia tridentata) had become established in the foreground. Aspen (Populus tremuloides) had increased in height and some stands were regenerating. By 1999 a 4x4 track had replaced the original horse trail, and the area in the foreground had been prescribed burned by the Forest service 10 to 15 years earlier, which reduced the cover of sagebrush and allowed various grasses to no dominate the site which was denuded in 1919. Snowberry (Symphoricarpos sp.) is also present in 1999. Only part of the aspen stand (right-center) in the prescribed burn successfully regenerated. A few scattered conifers are present in the 1999 photo that were not visible earlier.
