Disturbance and landscape history as a reference for evaluating forest management effects at a regional scale : examples from the Coast Range of Oregon, USA

Creator:: Nonaka, Etsuko
Abstract:: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement...

Forestry & Communication : A Coos Bay Case Study

Creator:: Livingstone, Tasha
Abstract:: This thesis combines elements of forestry, interpersonal communication, and rhetoric to describe where residents of Coos Bay and North Bend Oregon obtain information about forests and forest uses, and how they view the credibility of that information. As a qualitative exploratory study, grounded theory methodology was used to develop theme...

Comparing structure and development of Douglas-fir old-growth, plantations, and young natural forests in western Oregon

Creator:: Dowling, Christopher D.
Abstract:: Ages, diameter growth, density, tree size, and species were studied in old-growth, plantation, and young natural Douglas-fir stands in three areas in western Oregon: the western and eastern Coast Range and the western Cascades. The purpose was to compare the development of these three stand types and to determine whether...

Ground dwelling beetles in early and late successional forests in the western Cascades of Oregon

Creator:: Heyborne, William H.
Abstract:: The effects of forest cutting on forested systems and the biotic components of those systems has been at the forefront of scientific research. The inventory and monitoring of biodiversity is one technique used for measuring the effects of forest management. Because bioinventory studies are expensive, indicator species are often sought...

Mixed-conifer forests of central Oregon : structure, composition, history of establishment, and growth

Creator:: Merschel, Andrew G.
Abstract:: The structure and composition of mixed-conifer forest (MCF) in central Oregon has been altered by fire exclusion and logging. The resulting increased density, spatial contagion, and loss of fire resistant trees decrease the resiliency of this ecosystem to fire, drought, and insects. The historical and current composition and structure of...

Treatment options for controlling Brachypodium sylvaticum and impacts on native vegetation

Creator:: Fjeran, Taylor K.
Abstract:: 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...

Assessment of the accuracy of forested classifications within two broad-scale remotely-sensed vegetation databases in eastern Oregon

Creator:: Langhoff, Cory A.
Abstract:: 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...

Using oral histories to document changing forest cover patterns : Soap Creek Valley, Oregon, 1500-1999

Creator:: Zybach, Bob
Abstract:: This thesis examines forest history of a portion of the Douglas-fir Region: Soap Creek Valley, a 15,000 acre sub-basin of the Luckiamute River in northern Benton County, Oregon. The primary reasons for the research were to test oral history methodology, document sub-basin scale forest cover pattern changes, and determine basic...

People in the forests : interactions between community and forest health in Wallowa County

Creator:: Kelly, Erin Clover
Abstract:: 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)...

Economic Benefit from Allowing Wildfires to Burn in Federal East-Side Cascade Forests

Creator:: Gagnon, Aaron R.
Abstract:: 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...
