In this study an improved model of biomass and nutrient estimation of coastal Douglas-fir (Psuedotsuga menziesii) in the Pacific Northwest has been developed across a wide range of stand management regimes. This study quantifies and defines the type and intensity of biomass harvest and associated removal for actively managed stands...
Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...
This thesis seeks to analyze the relationship between economic growth and environmental quality, in this case measured by forest cover, and analyzes whether this relationship is consistent with an Environmental Kuznets Curve. Additionally the relationship between population density and forest cover was analyzed. A simple theoretical model is derived that...
Wildfire exclusion over the past century or more has resulted in extensive fuel accumulations throughout much of the West that combined with recent climatic patterns have increased the frequency of relatively uncommon, large, high-severity wildfires. Forest restoration treatments intended to alter landscape-level fire disturbance patterns can be difficult to implement...
This analysis explores potential changes in the behavior of Oregon's Supplemental Nutrition Assistance Program (SNAP) participants after the 2008 recession. I examine this using individual-level administrative data from the State of Oregon in a linear probability model and a duration model. After controlling for a standard set of factors known...
The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...
