Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...
The objectives for the use of the Oregon State
University college forest include providing both facilities
for research and teaching, and providing funding through
timber harvest. The older age-classes of the forest are
valuable for attaining both objectives. The opportunities
and costs of removing acreage in the older age classes...
Forest and wildlife habitat analyses were conducted
at the H.J. Andrews Experimental Forest in the Central
Cascade Mountains of Oregon using remotely sensed data and
a geographic information system (GIS). Landsat Thematic
Mapper(TM) data were used to determine forest successional
stages, and to analyze the structure of both old and...
This thesis examines the Schultz Fire as a case study to explain the complex history of fire suppression management in America’s forests, and to gain further understanding of how management practices have affected the increase in fire severity levels and how forests respond to such a disturbance. The thesis objectives...
This thesis focuses on the creation of a new collaborative website to connect key forestry topics to tourists and forest recreationists. It is divided into two main sections; the first explains the purpose and methods for creation of a new web-based educational tool called Explore Oregon Forests. Created through a...

Outreach and Education in Forest Action Plans of State Forestry Agencies
This study describes the composition and structure of forests within the immediate
vicinity of Northern spotted owl (Strix occidentalis caurina) nest sites in the Klamath,
Coast, and Cascade provinces of western Oregon and the Olympic province, Washington.
I compared forest stand data collected at 105 nest sites with data from...
The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...
Public land ownership withdraws property from the tax base of local
property tax districts. Publicly-managed lands occupy approximately 17.5
million acres of forested lands in Oregon (inclusive of federal, state, and county
ownership). To compensate local taxing districts for foregone property tax
collections, Congress enacted a series of federal revenue-sharing...
An accuracy assessment of two broad-scale vegetation databases for eastern Oregon, both developed from satellite imagery, was performed to assess the usefulness of the databases for forest landscape planning and assessment efforts. The two databases were the Oregon Department of Forestry (ODF) vegetation database and the U.S. Geological Survey National...
Starting more than 60 years ago, a complex of four forest fires occurring at six-year intervals burned almost 400 square miles of
virgin Douglas-fir forest in the northwestern Coast Range of Oregon. The area, which became known as the Tillamook Burn, was the focus
of an unprecedented reforestation effort drawing...
In this thesis I examine the question: can allowing a wildfire to burn this year result in a net positive economic gain? To answer this question I created 2,500 multiple sets of paired scenarios (called a fire of interest) which consist of ignitions, vegetation growth, and timber harvest over the...
Forests of the Inland West have been experiencing forest health problems arising from over a hundred years of fire suppression, logging, grazing, and mismanagement. Rural communities, meanwhile, have seen escalating unemployment, an exodus of young families, and a dearth of middle-income jobs. The objectives of this thesis are to: 1)...
Strategic planning for forests subjected to multiple uses is important for management that sustains and balances these many uses. In the wildland urban interface where forests are in the backyards of members of the public who avidly recreate in them, it is also important to include the community in the...
Salvage-logging and artificial seeding of grass following wildfire are common practices in coniferous forests of the western United States, yet few studies have
quantified the ecological effects of these post-fire activities. The effects of post-wildfire salvage-logging and grass-seeding on vegetation composition, aboveground biomass, and growth and survival of Pinus ponderosa...
The forest health of the Blue Mountains of eastern Oregon and Washington has sustained great impacts primarily caused by disease and insect epidemics. In order to restore forest health and reduce fuel loads, management tools like prescribed fire and mechanical chinning are being tested by forest managers in the region'...
This study involved the development of two bilingual and inquiry-based forest education programs within the Central Willamette Valley of Oregon. The first program used the participatory research (PR) process to engage 7th and 8th grade Latino students as participatory researchers to interview members of their community to learn their perspectives...
This thesis explores the complexity of relationships between communities and the ecosystems in which they live through a focus on forest restoration and fuels reduction on private land. As a case study, research took place in the Klamath-Siskiyou region of rural Northern California, in Humboldt and Siskiyou counties. The research...
In the Coast Range of western Oregon, some natural resource managers are converting red alder-dominated riparian areas to conifers to increase the future source of in-stream large wood for salmonid habitat. However, studies in Alaska have shown red alder-dominated riparian areas support greater invertebrate biomass compared to conifer-dominated areas. In...
