Description:

Plate 1084X. Sage Valley 1948 – 1953 – 1961 – 2005 This Photo Plot Transect was established by the Forest Service in 1943 to monitor range conditions in Sage Valley. The transect is 2,650 feet in length. According to early narrative reports, the area was very heavily grazed by domestic sheep when the transect was established. “The soil shows considerable signs of deterioration . . . [erosional] pavement is present…and many of the shrubs and grass clumps are mounded. A wash 4-6 feet deep drains the bottoms.” “The conditions that impressed me most were the very poor litter and excessive bare soil, widespread erosion pavement and quality of the cover. Recent storms caused much local soil disturbance both from sheet and splash erosion standpoints…erosion pavement is dense along the east portion of the transect…and the depressions between vegetation are most conspicuous.” In 1953, I.H. Johnson noted that the vegetation and soil trends were still downward, even though the amount of permitted sheep use had been reduced. When the transect was remeasured in 1978, however, Dr. Jim Bowns found that range condition had improved. “An overall assessment of this area is that the trend has been up since the 1940’s and the condition is presently high fair to low good. This is most apparent in improved soil conditions and species composition…The gully…mentioned by Cottam..[in 1943]…is hardly distinguishable at the present time.” Plate 1084x is viewed west from the end of the Photo Plot Transect. Silver sage and native grasses appear to have increased. Spruce have invaded the meadow, but elsewhere that species has declined due to recent attacks by insects and disease, which have killed most of the larger trees. Aspen on the right has declined. A few stands, however, regenerated 30 years ago when deer numbers were low, but not before or since due to repeated ungulate herbivory (Kay and Bartos 2000). The area is still grazed by domestic sheep and had been when the 2005 retake was made.
