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 ...
Understanding place as a cultural system: implications of theory and method
This dissertation seeks to provide insight into the relationships between public philosophy and the theoretical and methodological implications of social inquiry; to increase understanding of what it means to conceive of place as a cultural system; and to increase understanding of what it means to take a civic science approach ...
Simulation of bidirectional reflectance, modulation transfer, and spatial interaction for the probabilistic classification of Northwest forest structures using Landsat data
Satellite remote sensors sample the upwelling reflected radiance in the form of digital images. A hierarchical model linking several sub-models of the image acquisition process and the spatial interaction of the classes has been developed to infer forest structure classes from these samples. Forest classifications exhibit ...
