Plate 1139X. Sidney Valley 1943 – 1948 – 1953 – 1978 – 2005 This Photo Plot Transect was established by the Forest Service in 1943 to monitor range conditions in Sidney Valley. According to early narrative reports, the area was heavily grazed by livestock when the transect was established. In 1948, W.P. Cottam noted, “that grazing is severe here is evidence by the fact that Stipa lettermani is utilized much more than is general throughout the ranger district. Soil erosion is a serious problem on these gentle slopes. Grass clumps are frequently hummocked and [erosion] pavement is frequently conspicuous on soil unprotected by grass”. After remeasuring the transect in 1948, W.P. Cottam noted that what was once a domestic sheep allotment, had been changed to cattle use, but that “the amount of utilization [was still] far too great…” However, I.H. Johnson reported that the soil and vegetation trends were up in 1953. While in 1978, Dr. James Bowns found that “species composition has improved and ground cover had increased. For this site the range condition is good and trend is up.” Plate 1139x is viewed southeast from the end of the Photo Plot Transect back to its starting point. The truck in the 1943 image is on the transect’s centerline. The road seen in the early images has not been used in many years. Plant cover on the meadow has increased, while bare soil has declined. Conifers, in the distance, have increased, while aspen has declined. Many mature spruce, though, were recently killed by insects and disease. Some of the dead trees have been salvaged logged. Aspen has not regenerated due to repeated ungulate herbivory (Kay and Bartos 2000). The area was actively being grazed by cattle in 2005.
