Aboveground vegetation and viable seed bank of a dry mixed-conifer forest at a wildland-urban interface in Washington state

Creator:: Snider, Gabrielle
Abstract:: Dry coniferous forests in the western United States are experiencing severe wildfires, insect outbreaks, forest disease epidemics and a growing presence of invasive species. Policies strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI) where communities and forests intersect. However, these areas present restoration challenges as they tend...

Wildfire risk management : strategic interaction and spatial interdependence

Creator:: Busby, Gwenlyn M.
Abstract:: In this dissertation, I examine how the spatial configuration of forest ownership influences the risk-mitigating behavior of public and private forestland owners over time. I determine whether or not the predicted equilibrium outcomes are socially optimal and, if not, whether the introduction of regulation, liability, or private insurance would lead...

Host and Pathogen Contributions to the Populus–Sphaerulina Pathosystem

Creator:: Mondron Kyle T.
Abstract:: Sphaerulina musiva is a fungal pathogen that causes Septoria leaf spot and stem canker on susceptible Populus species and hybrids. In this thesis, host and pathogen contributions to Septoria stem canker disease were explored through: 1) a greenhouse study associating Septoria stem canker phenotypes with molecular markers from a genetic...

Complexity of food web interactions in a large mammal system

Creator:: Eisenberg, Cristina
Abstract:: Food webs consist of a combination of bottom-up (resource-driven) and top-down (predator-driven) effects. The strength of these effects depends on the context in which they occur. I investigated food web (trophic) relationships between wolf (Canis lupus) predation, elk (Cervus elaphus) herbivory, aspen (Populus tremuloides Michaux) recruitment, and fire. The study...

Effects of Subsampling Trees and Imputation Methods on the Accuracy of Height-to-Crown-Base Predictions for Douglas-fir in Southwest Oregon

Creator:: Allensworth, Elijah J.
Abstract:: Accurate estimates of height-to-crown-base (HTCB) are essential for the reliable projections of stand structure over time required for sustainable forest management. Yet, HTCB often measured alongside total height (HT) for only for a subsample of trees in traditional stand-based inventories and must be imputed for all others. We compared the...

Evaluation of Taper and Volume Estimation Techniques for Ponderosa Pine in Eastern Oregon and Eastern Washington.

Creator:: Pancoast, Alexander D.
Abstract:: The growing need for accurate forest biomass and carbon estimates has sparked a recent re-examination of direct volume estimation and taper modeling techniques. Additionally, the need for increased precision of biomass and carbon estimates drives a need to improve the techniques used to evaluate these models. Taper equations have an...

Strategies for sampling and estimation of aboveground tree biomass

Creator:: Poudel, Krishna Prasad
Abstract:: The issue of global climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of quantifying forest biomass in recent years. The official U.S. forest carbon reporting is based on the forest biomass estimates...

Phylogenetic Identification of Pathogenic and Endophytic Fungal Populations in West Coast Douglas-fir (Pseudotsuga menziesii) Foliage

Creator:: Daniels, Hazel A.
Abstract:: Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...

Estimating Forest Inventory Attributes Using Airborne LiDAR in Southwestern Oregon

Creator:: Shin, Joonghoon
Abstract:: This thesis mainly consists of two parts: (1) comparing statistical modeling methods based on the area-based approach (ABA) for predicting forest inventory attributes using airborne light detection and ranging (LiDAR) data (Chapter 2), and (2) suggesting a new methodology fusing the individual tree detection (ITD) approach and the ABA for...

A characterization of seasonal pools in Central Oregon's high desert

Creator:: Dlugolecki, Laura
Abstract:: Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...
