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:

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.

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,...
