Four centuries of soil carbon and nitrogen change after severe fire in a Western Cascades forest landscape

Creator:

Giesen, Thomas William

Abstract:

Fire is a major disturbance process in many forests. Long-term studies of the biogeochemical effects of fires, especially on soils, are very rare. Consequently, long-term effects of fire on soils are often hypothesized from short-term effects. In a chronosequence study, I studied 24 western Cascades (Oregon) forest stands thought to...

Effects of burrowing by mountain beaver (Aplodontia rufa) on soil in a young forest in the Oregon Coast Range

Creator:

Russell, William Ogburn, 1964-

Abstract:

Soil effects from mountain beaver (Aplodontia rufa ) burrowing were investigated in Oregon Coast Range soils formed from Tyee sandstone. The potential for observed changes in soil to affect productivity was assessed. Soil horizons from mountain beaver mound soil and adjacent unmounded profiles were collected with a monolith-type quantitative sampler....

Vegetation and soil microbial communities three years after wildfire in spruce-fir forests of northwestern Wyoming

Creator:

Hooke, Jennifer Suzanne

Abstract:

The Normalized Burn Ratio and Composite Burn Index were used to classify burn severity in three sites that experienced lightning-ignited wildfire in the year 2000. The effect of burn severity (unburned, low, moderate, and high severity classes) was investigated on vegetation and soil microbial community composition. Vegetation communities showed a...
