The degree of wildfire risk depends on both the probability of an ignition and the potential for damage or harm (such as loss of trees, homes, or even lives). Recognizing that you may have a high wildfire risk is the first step in doing something about it. Whether you own...
Paterson’s curse is a member of the borage family (Boraginaceae). It is native to Mediterranean Europe and North Africa but has spread to southern Africa, South and North America, Australia, and New Zealand. Outside of its native habitat, it is an aggressive, drought-tolerant plant that adapts to many soil moisture...
This publication provides basic information on tree growth, characteristics that define wood quality, and the implications of common silvicultural (tree tending) activities on wood quality. It is at best a summary—tree growth is an immensely complex process, and not all aspects of wood formation are fully understood. Most of the...
Coastal waters, lakes, and streams in the Pacific Northwest provide a variety of seafoods including salmon and many other fish, clams, oysters, shrimp, and crab.

This publication focuses on how to design a soil nutrient monitoring strategy that fits today’s requirements for record keeping and increased accuracy in managing nitrogen (N), phosphorus (P), and other nutrients. We advocate the use of management units or zones for soil testing and nutrient application. To measure a real...
Family members who play a major role in caring for elderly relatives frequently ignore their own needs. Some find themselves virtually homebound and consumed by caregiving tasks. When caregiving is prolonged over months and years, the self-sacrifice is particularly harmful. We have prepared this publication to help you maintain your...
Hens stop laying eggs for a variety of reasons. External or internal stimuli affect hormone levels, which change the condition of the ovary and oviduct, the organs responsible for egg production. The result of these changes is the reduction or cessation of egg production. The most common stimuli that affect...
It is imperative that residues of these compounds be eliminated in poultry and eggs or be within the tolerances established by the U.S. Department of Agriculture and the U.S. Food and Drug Administration when your flock is marketed or eggs are sold.

Curly dock (Rumex crispus L.) is a perennial. It does
not have creeping roots or rhizomes (Figure 1). Leaves
are oblong to nearly lanceshaped, often 12 inches or more
long, with wavy (crisped) margins (Figure 2). Erect, generally
unbranched stems up to 5 feet tall are produced in spring

High-quality forages, such as alfalfa and grasses, are important for efficient milk production from dairy cows. Forages provide the effective fiber that is critical for good health and longevity. Inadequate
effective fiber in the cow’s diet is one reason for acidosis and milk fat
depression. Historically, when forage quality changed,...
Annual ryegrass (Lolium multiflorum Lam. or Lolium perenne L. ssp. multiflorum (Lam.) Husnot, also called Italian rye grass) is a cool season annual bunchgrass native to southern Europe. It is closely related to perennial ryegrass (Lolium perenne L.). Both are widely distributed throughout the world, including North and South America,...
Orchardgrass (Dactylis glomerata L.) is native to western and central Europe, but has been grown in North America for more than 200 years. In the 1830s, settlers in western
Virginia recognized the forage value of shade tolerant
D. glomerata plants growing in an orchard.
Tall fescue (Festuca arundinacea Schreb.) is a perennial, cool-season bunchgrass that is grown for pasture, hay, and silage. Native to Europe and North Africa, it was introduced from Europe to North and South America.

Describes the requirements for incubating eggs, brooding, rearing, breeding, and feeding ratites; most information is based on grower trial and error and is modified from poultry information. Underscores the importance of overcoming various obstacles, such as checking whether ratites are considered livestock in your area, establishing markets, and eliminating the...
In nature, chicks hatch after 2 to 4 weeks of incubation by the parents, most often the hen. The hatched chicks provide the stimulus to the hen to change her work from incubating eggs to brooding young. This form of brooding chicks is the easiest if only a few chicks...
Four speedwell species are important weeds in the Pacific Northwest:
• Ivyleaf speedwell (Veronica hederaefolia L.)
• Persian, birdseye, or winter speedwell (Veronica persica Poir.)
• Creeping speedwell (Veronica filiformis Sm.)
• Purslane speedwell (Veronica peregrina L.)
The first decision to be made is whether to incubate eggs naturally or artificially. Natural incubation uses a broody hen to incubate eggs by sitting on them in a nest. Broody hens, when available, work best for small clutches of eggs.
Yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria
dalmatica) are members of the figwort (Scrophulariaceae) family.
They were introduced into North America as ornamental plants because of their showy, snapdragon-like flowers. Yellow toadflax was brought from Wales in the mid-1800s as a garden flower by Ranstead, a Welsh Quaker who...

Squarrose knapweed, introduced from southwest Asia and the Middle East, became weedy in northern California and Utah by the early 1950s. How it
was originally introduced is not known, but its spread in California
and Utah was associated with the trailing of range sheep. Squarrose knapweed grows in the Klamath,...
Creeping buttercup (Ranunculus repens L.) probably is the most troublesome of several members of the buttercup family that are weeds in the Pacific Northwest. There are many native species of buttercup in the Pacific Northwest, but the weedy species are of European origin. It’s likely that they were introduced as...
The Horsetail (Equisetaceae) family comprises 30 species, all in the ancient genus Equisetum. During the Carboniferous age (more than 230 million years ago), the Horsetail family was the dominant plant group in the world, with plants reaching gigantic size. Two basic forms of horsetails survive today. One is the hollow,...
Bulbous bluegrass is another example of an introduced
European plant that escaped to become weedy. The first reports
of its growth in the United States were experimental
plantings at Arlington, Virginia, in 1907, and one at Pullman,
Washington, at about the same time. It was produced commercially
in southern Oregon...
Common groundsel, native to Europe, is now common throughout the temperate regions of the world. It is widespread in Oregon, Washington, and Idaho, but most common west of the Cascade Mountains.

Oregon State University researchers made a significant discovery in 1958. They found that the underlying cause of white muscle disease is a dietary deficiency of the trace element selenium (Se). There is a fairly clear-cut relationship between soil, plant, and animal factors. Certain soils, including some formed by volcanic action...

Even refrigeration won’t guarantee that smoked fish will stay safe to eat. The bacteria that cause botulism food poisoning could start...
Wild garlic (Allium vineale) was introduced from Europe where it was used as a food flavoring. It is found in pastures, lawns, ornamental beds, and several cultivated crops. It grows west of the Cascades from Vancouver Island south into northwest Oregon.
Red sorrel (Rumex acetosella) also is known as sheep, horse, field, mountain, and cow sorrel or sour dock. This European weed grows throughout the Pacific Northwest under various soil and climate conditions.
Life is filled with changes. Sometimes those changes involve loss. When we lose someone or something important to us, we grieve. Although the death of a loved one is generally the most intensely and deeply felt loss, many life changes can involve loss and cause us to grieve.
