Sidney Valley

2005

Description:

Plate 1144X. Sidney Valley 1941 – 2005 Viewed northwest across Sidney Valley. Plates 1143x and 1144x form a panorama. The foreground in the retake has been disturbed by construction - - a gravel pit lies immediately behind the photopoint. Otherwise, plant cover appears to have increased on 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. Some of the bug-killed spruce has 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.
