Plate 1146X. Sidney Valley 1941 – 2005 Viewed north up Sidney Valley. A spruce has become established in the foreground. Plant cover appears to have increased in the meadow, despite yearly grazing by cattle - - see Plates 1138x, 1139x, and 1140X. In the distance, conifers have increased, while aspen has declined. Many mature spruce, though, were recently killed by insects and disease. Aspen has not regenerated due to repeated ungulate herbivory (Kay and Bartos 2000). The area was actively being grazed by cattle in 2005.
