The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...
It doesn’t come easy! Does any of your woodland
property look like the alder stand at the left? If your goal
is to convert this kind of ground to a productive conifer
forest, you should know it can be a challenging task.
You’ll have to do something with all that...
Western hemlock forests in the coastal areas of Oregon are some of the most productive and diverse forests in the world. This rich diversity represents both a challenge and an opportunity for woodland owners interested in managing western hemlock on their property.
The organic compound tracers of atmospheric particulate matter, as well as organic carbon (OC) and elemental carbon (EC), have been characterized for samples acquired during the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia) from Gosan, Jeju Island, Korea, from Sapporo, Japan, and from Chichi-jima Island in the western North Pacific,...

Igneous oceanic crust encompasses ~60% of Earth’s surface and is composed of basalt glass and mafic, ultramafic, and felsic minerals. A vast marine aquifer lies within the crust, exchanging geochemically altered fluids with seawater from the overlying ocean at ridge crests, flanks, seamounts, and outcrops where permeable crust is exposed....

This publication demonstrates one way of organizing and preparing a forest management plan for your property.
By no means should you consider this the best or only way for you to plan; conditions vary—and so should your approach to planning.
In some forest situations, seedlings readily spring up from seeds produced by nearby trees, reducing (or even eliminating) the need to plant trees. Often, though, conditions aren’t right for this
natural regeneration to happen quickly, or with the desired kinds of trees. Therefore, planting tree seedlings by hand usually is...
The listing of many Pacific Northwest anadromous fish stocks as threatened or endangered has heightened the need to protect or enhance the health of entire river systems. Salmon, steelhead, and other anadromous fish swim from the ocean to the headwaters of their home river, where they spawn. Their young hatch...
Successful reforestation of your harvested timberland is more than just
planting a few trees and hoping they will grow. To ensure success,
you first must answer several key questions:
• What species should I plant?
• What kind of seedlings should I select?
• How can I tell whether their...
This publication is for people involved in the important task of rehabilitating and restoring Oregon’s threatened or degraded habitats. Growing numbers of private landowners, local organizations, and government entities are embarking on projects to restore the health or function of their riparian areas, wetlands, prairies, savannas, and other habitats. Choosing...
Hatchery supplementation of anadromous salmon is extensive across the Pacific Northwest region with millions of juvenile salmon stocked annually. The influence of hatchery-origin fish as prey items in recipient ecosystems has been explored, but influences of these fish on broader stream nutrient dynamics has not been well-studied. Salmon-derived nutrients (SDN)...
The genome of a herpesvirus highly pathogenic to rabbits, leporid herpesvirus 4 (LHV-4), was analyzed using high-throughput DNA sequencing technology and primer walking. The assembled DNA sequences were further verified by restriction endonuclease digestion and Southern blot analyses. The total length of the LHV-4 genome was determined to be about...

This manual describes the rules for reforesting after harvest of small woodlands, gives guidance for the decisions the landowner must make, and gives step-by-step instructions for planting and taking care of seedlings.
Myc is a pleiotropic transcription factor that is involved in many cellular activities relevant to carcinogenesis, including hepatocarcinogenesis. The zebrafish has been increasingly used to model human diseases and it is particularly valuable in helping to identify common and conserved molecular mechanisms in vertebrates. Here we generated a liver tumor...
Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and cultural importance to coastal Oregon and California. Local scale distribution of P. lateralis is thought to be associated with...
Phytophthora borealis and Phytophthora riparia, identified in recent Phytophthora surveys of forest streams in Oregon, California and Alaska, are described as new species in Phytophthora ITS Glade 6. They are similar in growth form and morphology to P. gonapodyides and are predominately sterile. They present unique DNA sequences, however, and...

The dynamics of the growth of linear disturbances
to a chaotic basic state is analyzed in an asymptotic model of
weakly nonlinear, baroclinic wave-mean interaction. In this
model, an ordinary differential equation for the wave amplitude
is coupled to a partial differential equation for the zonal
flow correction. The leading...
There is an urgent need to clarify how different stocks, or subpopulations of fish species, are vulnerable to fishing pressure and unfavorable ocean conditions because of the increasing demand on fisheries for human consumption. For marine fishes, the potential for high gene flow increases the difficulty in determining the number...
•Background: Managers of landscapes dedicated to forest commodity production require information about how practices influence biological diversity. Individual species and communities may be threatened if management practices truncate or simplify forest age classes that are essential for reproduction and survival. For instance, the degradation and loss of complex diverse forest...

Preventative motor fault detection is of prime importance for modern plant management. During research into rotor faults, performed at the Motor Systems Resource Facility (MSRF), an optimized rotor fault detection and classification method was proposed. In critical process applications, the suggested method would provide the foundation for continually monitoring a...
Honey wine, also known as mead, is one of the oldest alcoholic beverages known to man. Made primarily from honey, water, and yeast, this beverage has recently been experiencing a resurgence in popularity. It is imperative that commercial producers focus on consistently creating quality products to differentiate themselves from competitors...
Each Christmas tree species requires special skill and specific knowledge to be grown successfully. True fir Christmas trees are no exception. In fact, the true firs, many argue, require more detailed knowledge, more specific site requirements, and more individual attention than other species.
Over the past 30 years, Christmas trees have become an intensively managed horticultural crop. During this period, higher standards and increasing competition have given the edge to growers who are progressive and highly motivated. Whether you’re a large or small producer, your trees must have consistently high quality for successful...
Christmas trees are an enduring holiday tradition. U.S. producers supply about 35 million trees annually. The past few decades have seen the Pacific Northwest’s rise to prominence as the leading Christmas-tree producing region in the United States. With a combined annual production estimated at more than 11 million trees, Oregon,...
