The Natural Resources Division (NRD) of the Confederated Tribes of Grand Ronde (CTGR), in cooperation with the Bureau of Indian Affairs (BIA), proposes the regeneration harvest and commercial thinning of four timber sales on the Reservation of The Confederated Tribes of Grand Ronde (CTGR). The CTGR has a 20-year management...
Field studies were conducted in 1998 and 1999, to evaluate glyphosate and glufosinate for control of redroot pigweed, common lambsquarters, hairy nightshade, and barnyardgrass in herbicide-resistant sugarbeets. Treatments that included two or three applications of glyphosate, regardless of rate, or glyphosate applied once in combination with BAS 656 07 H...
Water quality changes along hyporheic flow paths may have important effects on river water quality and aquatic habitat. Previous studies on the Williamette River, Oregon, showed that river water follows hyporheic flow paths through highly porous deposits created by river channel meandering. To determine water quality changes associated with hyporheic...

Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and...
On January 5, 2000, the National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation (HHE) from the United States Forest Service (USFS), Region 6, Office of Natural Resources. The request listed nausea, rashes, headaches, and dizziness as symptoms reported by Foresters who use...
Concerns about the extent to which major Pacific Northwest floods over the last decade might have been exacerbated by logging have heightened the need for a better scientific understanding of the role of forest maturity on snow accumulation and melt. To address this need, a multi-scale field and modeling study...
Stream systems in the Pacific Northwest have come to be understood in the absence of beaver (Castor canadensis). To understand the effect of beaver upon riparian plant communities, four basins in the lower Alsea drainage were examined to determine the effect of beaver and their impoundments on streamside herbaceous/shrub and...
We analyzed the effects of pathogens and insects on forest succession in the absence of
fire or management, addressing a number of related questions:
1. What is the rate of change in such forests?
2. How significant are the roles of pathogens and insects in the forest change?
3. How...
This publication is aimed at watershed councils, government agencies, and specialists (foresters, wildlife and fisheries biologists) interested in riparian area silviculture or watershed restoration. It contains information on the ecology of riparian forests and a checklist of recommended practices and common mistakes made in restoring conifers to hardwood-dominated riparian forests....
For the past ten years, Douglas-fir on the Oregon and Washington coast has shown a progressive decrease in height and diameter increment as a result of Swiss needle cast, which is caused by Phaeocryptopus gaeumannii. In this contribution, we discuss the effects of silvicultural operations on Swiss needle cast and...
By the early 1990s, the citizens of Tillamook County recognized that environmental problems facing Tillamook Bay threatened the very future of those residing here. Declining fish runs meant loss of income for commercial fishermen, tackle shops, hotel owners, and other fishing - dependent businesses. Decreasing water quality meant violations of...
Vegetation and geographic region including forest steppe in Khangai Range, mountain steppe in Mongol Altai, desert steppe in the Great Lakes Depression, the Valley of the Lakes and Gobi Altai Mountains and Zuungar and Trans-Altai Gobi were covered by the scope of the investigation. 181 samples of 123 plant species...

Due to its frequent use in agriculture and its frequent detection in surface water,
atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...
In its quest to promote the wise utilization and conservation of the United States' ocean and coastal resources, the National Sea Grant Program sponsors a vast array of research and educational ventures. Much of this is published, either in print or electronically. Locating this information can be an adventure even...

On April 7, 2000, the National Marine Fisheries Service (NMFS) received a request from the U.S. Army Corps of Engineers, Portland District (COE) for Endangered Species Act (ESA) section 7 formal consultation for programmatic coverage for a proposed Regional General Permit (RGP) for certain stream restoration activities (habitat restoration using...
I conducted two separate studies, both related to the impacts of spring and fall prescribed fire on ponderosa pine (Pinus ponderosa Dougl. ex Loud.) forest soils in Eastern Oregon. The studies were either conducted at or linked to four stands of ponderosa pine, in the Malheur National Forest. Each stand...
PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental
margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net
tow stations along 5 lines (off Newport, Heceta Head, Coos Bay, the Rogue River, OR. and Crescent
City, CA.), to make continuous...

Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage...
Forty-seven isolates of Fusarium solani obtained from the roots of diseased and healthy conifer seedlings and forest nursery soil were tested for pathogenicity on young Douglas-fir germinants under controlled laboratory conditions. Isolate virulence varied widely; a few were highly virulent whereas many were classified as non-pathogenic. Isolates from the roots...
Thirty-three isolates of Fusarium acuminatum obtained from inland Pacific Northwest forest nurseries were tested for their pathogenicity on young Douglas-fir germinants under controlled laboratory conditions. Tested isolates were from forest nursery soil, roots of healthy-appearing and diseased conifer seedlings, Styrofoam and hard plastic containers, conifer seeds, 411 and adult fungus...

Critics of higher education urge educators to transform their institutions so as to align them with the needs of the twenty-first-century learner. However, colleges desiring to survive in a rapidly changing external environment often discover they must first find a way to make
fundamental changes in their institutional culture. Some...
In spring time, animals, goats and sheep in particular, prefer to eat flowers Pulsatilla multifida, and Iris tenifolia. Pulsatilla's flower contains sugar 20.33, starch 6.71, cellulose 19.15, lignin 6.50, and acid detergent fibre (ADF) 24.88, neutral detergent fibre (NDF) 32.55, hemicellulose 7.67, and protein 14.27 percent. Dry matter digestibility (DMD),...
The opportunities for expanding water supplies in Oregon coastal municipalities are becoming increasingly limited. New water quantity and quality regulations, particularly those designed to protect and rebuild salmon runs, constrain water supply options. At the same time, however, demand for water is increasing. Coastal communities continue to grow in population...
