There are about 80 million single-family dwellings (SFD) in the United States,
predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is
typically the largest single investment of a family, and is often not covered by earthquake
insurance, even where it is available. Of all the houses...
Using qualitative research methods we examined how group ranch privatization and settlement of individual Maasai households across the landscape have affected traditional livestock herding and social capital mechanisms of Maasai livestock herders. This process has altered decision-making processes, social networks, and cooperation of Maasai herders and limited access to water...
This symposium dealt primarily with one important aspect of wood quality, namely specific gravity as determined in standing timber by the increment core sampling method. It covered the status of research in this area, the importance of the work, present and potential uses for wood density data, and the need...
Postfire logging recoups the economic value of timber killed by wildfire, but whether such forest management activity supports or impedes forest recovery in stands differing in structure from historic conditions remains unclear. The aim of this study was to determine the impact of mechanical logging after wildfire on soil bacterial...

Using a qualitative approach, the authors tested a crime
typology developed for tourism destinations in a U.S. National
Forest recreation setting. Specific objectives were to
classify the attributes of crime and violence, examine the effects
of crime and violence on visitor demand, and suggest
methods of prevention and recovery. A...
Across western Oregon, Washington, and British Columbia, forest management practices over the past century reduced the amount of late-successional forest while
simultaneously increasing the amount of young (less than 80 years old), managed
Douglas-fir (Pseudotsuga menziesii) dominated forests. Recently, concerns over loss of late-successional habitat pushed management objectives on public...
Wood shear walls are the main lateral force-resisting system for wood-frame construction. Water intrusion and subsequent decay around connections can significantly impact shear wall behavior, but these problems are seldom studied. In this study, effects of water intrusion and fungal attack on shear wall capacity were examined using small-scale (610-...
Genetic control of cold hardiness in two-year-old seedlings was compared with that in 7-year-old saplings of 40 open-pollinated families in each of two breeding populations (Coast and Cascade) of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from western Oregon. In addition, the efficacy of bud phenology traits as predictors...
The purpose of this study was to investigate the effects of
logging on the productivity, structure and biomass of a periphyton
community developed in mountain streams. The three streams used
in this investigation were located in the coast range of Lincoln
County, Oregon. They were selected for similarity of habitat,...
Two experiments were conducted on the invasive plant species Potentilla recta in northeastern Oregon to investigate both biological and ecological characteristics of the species. Growth analysis was conducted on the plant at three sites over a period of two years (2002 and 2003). Relative growth rate (RGR) was calculated for...
Annual ryegrass (Lolium multiflorum) a major grass seed crop
in the Willamette Valley, Oregon, is presently burned in the fields
after harvest, causing considerable air pollution and general wastage
of a material which could be used in the manufacture of economically
important products. The cellulosic component of straw is relatively...
Canopy gap formation is a major factor contributing to maintenance of overstory species diversity and stand structure in forests and may be integral to development of understory shrub and herb layers as well. Acknowledgement of gap formation as a fundamental feature of natural forests has led to consideration of gaps...

Cooperation across ownership boundaries is critical to most conservation efforts in mixed ownership landscapes. Where owner objectives vary widely, as at public-private landownership boundaries, cooperation can be especially challenging. This research explores the opportunities and challenges for cooperative fire management among public and private forest managers in the John Day...
This is a PDF of material on the Oak Creek Website which was created in 2002. The main purpose of the site was to create an annotated bibliography of research activities in the watershed which surrounds the Oregon State University Campus. Because of its proximity to campus, many students and...
A flume study was conducted to investigate the influences of
changing hydraulic conditions on the bed morphology of a scoured pool.
During a simulated storm runoff event, responses of the pool were
tested under different conditions: clearwater flow, sediment supply at
steady rates, and two different sediment mixtures of the...
Early in the establishment of Pacific Northwest conifer plantations, herbaceous weeds often decrease seedling growth through competition for soil moisture during the dry summer months. Critical period studies have reported that reductions in competitive weed cover are necessary during the initial years of establishment to avoid reductions in seedling growth....
Interception of precipitation by forest canopies has been found previously to reduce rainfall intensity, but this effect is poorly understood. The goal of this research is to quantify the attenuation of rainfall intensity by forest canopy interception, with the specific objective of estimating the contribution of this attenuation to hillslope...
Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...
The education (particularly graduate education) of Americans
who were active in astronomical research between 1876 and 1941
is assessed for its effectiveness in preparing the astronomers for
careers in research. This period contains three dynamic changes:
the growth of American astronomy in becoming the world's leading
community of astronomers, the...
One of the most common practices regarding estimation of forest attributes is
the partitioning of large forested subpopulations into smaller areas of interest to
coincide with specific objectives of present and future forest management. New
estimators are needed to improve estimation of selected forest attributes in small areas
where the...
This proposal by the Coniferous Biome investigators requests support for the second year of a highly integrated series of investigations within the Analysis of Ecosystem program of the United States effort under the International Biological Program. The program for the Coniferous Forest Biome has been approved by the U.S. Executive...
In terms of production forestry, more often than not any species that is not the crop
species is considered a competitor as they are using finite growing resources that would
otherwise be available to the crop species. With specific regard to Douglas-fir
(Pseudotsuga menziesii (Mirb.) Franco) production in the Pacific...
The Fishery Division of the Oregon State Game Commission
continued in 1950, with activities of previous years embraced under
the general categories of research, management, and production. Some
activities were expanded or added where a need arose, and others were
reduced or eliminated. In general the over —all program followed...
To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...
Three studies were conducted to characterize and present early-seral
competition between Douglas-fir seedlings and the surrounding vegetation
communities during Pacific Northwest forest establishment. The first experiment
served as the foundation for this dissertation and was designed to quantify tradeoffs
associated with delaying forest establishment activities by introducing a fallow year...
Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...
Reintroduction of wolves to Yellowstone National Park (YNP) in 1995-96 provided a rare opportunity to observe the response of an ecosystem to the return of a top predator, including possible reversal of decades of decline of aspen, cottonwood, and tall willows suppressed by intensive herbivory on elk winter ranges. To...

Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...
Since at least the 1970s, rural areas in the western United States, as elsewhere across the country and world, have been subject to social, economic, and political forces that have resulted in novel demographic and land tenure trends when compared to previous decades. Collectively, these processes of restructuring have created...
This study was undertaken to evaluate the dry-weight-rank and
microscopic point methods for determining botanical composition on
perennial ryegrass (Lolium perenne L.) - subclover (Trifolium
subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) -
subclover pasture mixtures throughout a grazing season.
Botanical composition was determined on a monthly basis from...
