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....

Testing two applications of image analysis for use in species-independent biomass equations for western Oregon forests

Creator:

Gray, John Edward, 1946-

Abstract:

Remote sensing technologies have proven useful and cost-efficient for quantifying various forest vegetation characteristics over multiple scales. However, significant limitations were encountered in each of two related experiments conducted to explore their potential to supplement or replace traditional, single-species biomass equations for estimation of ground vegetation and tree overstory on...

Biologic activity in two western Oregon Douglas-fir stands : a research link to management

Creator:

Hope, Sharon Margaret

Abstract:

Information about forest substrate respiration, nitrogenase activity and mineralizable nitrogen may be incorporated into carbon and nitrogen budgets that comprise an important element of forest management planning. In this study, substrate respiration, nitrogenase activity and mineralizable nitrogen were measured in two western Oregon Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stands within...
