Oregon's rocky intertidal habitats have been subjected to gradually increasing human-use pressures as the coastal and tourist populations have risen over the years. Brosnan and Crumrine (1991,1992) have documented impacts to intertidal communities at Yaquina Head, Sunset Bay, and Haystack Rock that have resulted from people walking on the intertidal...

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...

Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests
millions of acres in California and the Pacific Northwest. Infestations range
from scattered plants to dense stands...

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...

Cover crops planted in late summer are an inexpensive way to build better soil for gardening. Cover crops often are
called green manure crops. They are grains, grasses, or legumes that will grow during fall and winter and that you
can plow, spade, or till under in the spring.
Communication is basic to a relationship. What is communication? The word means “to make common.” It is the process of interacting, of creating and negotiating meanings. Your feelings,

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,...

Measuring the flow rate of water is the first step to good water management. All water right holders in the State of Oregon must be able to measure the flow rate of the water being diverted.
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...
Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...
This publication gives basic information on choosing your
planting site, selecting the right species for the site, proper planting
techniques, and first-year care. Although you may be buying a tree
to add beauty to your home landscape,trees also serve other important
functions in your landscape.

The Douglas-fir needle midge can be a very destructive pest of
Douglas-fir. Infestation of new needles can be as high as 100 per-cent. Severe infestations can cause intolerable needle loss, and trees may take several years to recover. Needle loss is an especially serious problem in Christmas trees because of...
Fertilizing hops improves yield and quality by supplying the crop with ample nutrition in advance of demand. Producers must combine this goal with production costs and environmental stewardship. Fertilization should be based on yield and quality response, experience, and economics. Unfortunately, limited experimental data exist linking modern cultural practices, current...

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...
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,...
Agropyron spicatum, considered one of the most important native bunchgrasses in British Columbia, western Montana, the Columbia Basin and the area between the Cascades and Sierras and the Rockies, dominated millions of acres of pristine semiarid grass and sagebrush sites. It produced more herbage than all other associated species in...
Cash commodity sales from Oregon farms and

Although many people enjoy deer, these animals can be destructive
to gardens, orchards, and landscaped areas. Deer damage to
ornamental plants is associated with a variety of factors including
increasing numbers of deer, human population shifts to rural
and suburban areas, and landowners prohibiting deer hunting.
Moisture problems can occur in many places in homes and for many reasons: when high levels of moisture enter building cavities or get inside, when excessive moisture is produced indoors, or
when indoor air comes into contact with cold surfaces such as single-pane windows or uninsulated walls. Excess moisture often...

Long-term experiments were started at Pendleton and Moro, Oregon in the 1930's to evaluate the effects of tillage, fertilizer, and residue management on crop productivity in non-irrigated semi-arid regions. Coupled with multi-year varietal improvement, rotation, and green manure studies, they define those practices which sustain soil productivity and improve crop...
