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...
This thesis presents a design-oriented model for lightly doped CMOS substrates. The model predicts the substrate noise coupling between noisy digital and sensitive analog blocks in the early stages of the design. The model scales with the size and separation of these blocks and it is validated with device simulations...
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...
Soil in Field 2 at the USDA Forest Service Nursery, Coeur d'Alene, Idaho was assayed six times over a 2-year fallow period for potentially pathogenic Fusarium and Pythium spp. following incorporation of a corn cover/green manure crop. Populations of potentially disease-antagonistic Trichoderma spp. were also assayed. Soil populations of Fusarium...
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...
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...
On June 27, 2000, the National Marine Fisheries Service (NMFS) received a biological assessment (BA) and request from the Federal Highway Administration (FHWA) for Endangered Species Act (ESA) section 7 formal consultation for a bridge replacement project over Butte Creek along Oregon Highway 211 (Woodburn to Estacada Highway) in Marion...
The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...
On October 16, 2000, the National Marine Fisheries Service (NMFS) received a request from Portland District Army Corps of Engineers (COE) for Endangered Species Act (ESA) section 7 consultation for issuance of a Corps permit to Morse Brothers (Corps No. 2000-00844) for a habitat restoration project that will connect an...
Investigations were conducted from 1998-
2000 at the Potlatch Corporation's
Cherrylane Seed Orchard near Lewiston,
Idaho to evaluate presence and extent of
potentially pathogenic fungi on roots of
diseased stock and within the soil in current
and proposed plantation sites. The most
common group of pathogens encountered
was Fusarium spp.;...
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...
Prior to 1978, Dolly Varden Salvelinus malma were classified into an anadromous and interior form. Cavender (1978) classified the interior form as a distinct species, Salvelinus confluentus, the bull trout. Bull trout are large char weighing up to 18 kg and growing to over one meter in length (Goetz 1989)....
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...
The Umpqua National Forest (UNF) submitted June 3, 1999, January 14, 2000, and April 14, 2000 letters requesting consultation for a number of proposed activities that were determined likely to adversely affect Oregon Coast (OC) coho salmon (Oncorhynchus kisutch). Biological assessments (BAs) addressing the potential effects to these species accompanied...
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...
On September 22, 2000, the National Marine Fisheries Service (NMFS) received a request from the U.S. Army Corps of Engineers (COE) for Endangered Species Act (ESA) section 7 formal consultation for the West Fork Dairy Creek (Soupy Mud) erosion repair project (Corps No. 2000- 862). The project will repair the...

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...
The Oregon continental shelf waters are typically characterized by four to five major upwelling events that occur between May and October. The upwelled water is rich in nutrients, which fuels an increase in phytoplankton biomass. The onset of El Nino, however, can disrupt the normal physical processes along the Oregon...
The objective of this report is to describe the current increase in Douglas-fir tussock moth (Orgyia pseudotsugata McDunnough) activity in northern Idaho and Montana. The report also relates current conditions to historical and future trends and larger scale increasing tussock moth activity in surrounding western states.
On November 19, 1998 (OSB1998-0088), the National Marine Fisheries Service (NMFS) completed an Endangered Species Act (ESA) section 7 informal consultation with Oregon Department of Transportation (ODOT) for the Charlotte Creek Quarry Rock Production project. NMFS concurred that the proposed action was not likely to adversely affect Oregon Coast coho...
This Environmental Assessment (EA) will address the Klamath Falls Resource Area proposal to
upgrade the existing concrete stream ford on the CCC road (no. 41-14E-11) where it crosses Barnes
Valley Creek at T39S, R14 ½ E, Sec. 22 (see attached map, figure 1).
The proposed construction project would be done...
The Coos Bay, Medford, and Roseburg Bureau of Land Management (BLM) District Offices submitted May 25 and June 20, 2000, letters requesting formal consultation for a number of proposed activities that were determined likely to adversely affect Oregon Coast (OC) coho salmon (Oncorhynchus kisutch) and OC steelhead (O. mykiss). Biological...

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...
Food Insecurity exists whenever the availability of nutritionally adequate and safe foods or the ability to acquire acceptable foods in socially acceptable ways is limited or uncertain (LSRO, 1990). Factors that increase a household's risk for food
insecurity include being low income and not being able to access formal and...
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...
