The mobility and fate of phosphorus following municipal biosolids application to forest soils
Municipal biosolids are typically not used on the steepest of forested slopes in the Pacific Northwest. The primary issue in using biosolids on steep slopes is movement of constituents in biosolids to surface waters during runoff events. There is a particular concern with biosolids phosphorus (P), as this nutrient limits ...
Spatial and temporal variation in historical fire regimes of the Blue Mountains, Oregon and Washington: the influence of climate
To identify the influence of climate on spatial and temporal variation in fire, low- to high-severity fire regimes were reconstructed from tree-rings in the Blue Mountains. Fire recurrence, extent, severity and seasonality (low-severity fires only) were determined from fire scars and ages of 1426 trees sampled on 2914-8585 ...
Application of multivariate analysis techniques in understanding complex industrial processes: a pulp mill example
The financial and process benefits of improving the mill fiber line are widely acknowledged. However, process optimization of the fiber line is difficult due to the complex behavior of pulp and paper systems. The dissertation project focused on application of multivariate analysis techniques for understanding and improving ...
Wind stability of naturally regenerated and planted Douglas-fir stands in coastal Washington, Oregon, and British Columbia
Risk of wind damage is an important factor influencing forest management throughout the world. Managed forest landscapes of the coastal Pacific Northwest are undergoing a transition from dominance by naturally regenerated second-growth stands to Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) plantations. This analysis ...
