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
and...
Perennial ryegrass (Lolium perenne L.), also called English ryegrass, is a cool-season perennial bunchgrass native to Europe, temperate Asia, and North Africa. It is widely distributed throughout the world, including North and South America, Europe, New Zealand, and Australia.
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.

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.

The common name powderpost beetle loosely applies to three closely related beetle families, Lyctidae, Anobiidae, and Bostrichidae. Powderpost beetles breed in dead wood, as well as dried and cured lumber. It is their larvae’s feeding that reduces wood to what scientists call frass—a fine powder or a mass of small...
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...
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...

Blue mustard (Chorispora tenella) is a native of Russia or
southwest Asia. It first was documented in this country in
Lewiston, Idaho in 1929, and has spread throughout the
western plains states, the western portion of the United States,
and southern Canada.
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.

The public expects and deserves
a safe food supply. This
includes food free of antibiotic
residues. Congress has empowered
the Food and Drug Administration
(FDA) to examine and
closely monitor the use of animal
drugs in dairy herds across the
nation. This regulatory agency has
the power of enforcement action.
This guide addresses all aspects of volunteer program management, emphasizing the integration of volunteers into all areas of the organization. Underlying its suggestions is the authors' belief that the objectives of a volunteer program -- mutual benefit and shared responsibilities -- are achievable if salaried and volunteer staff participate equally...

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.
St. Johnswort (Hypericum perforatum), also called Klamath weed and goatweed, was introduced from Europe and was found in California about 1900. It was a major pasture weed west of the Cascade mountains from Tacoma south to central California until the successful introduction of the chrysolina beetle, a leaf-eating insect.
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.
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.
