The purpose of this watershed assessment is to provide an inventory and characterization of
watershed conditions in the Wilson River watershed and to provide recommendations that
address the issues of water quality, fisheries and fish habitat, and watershed hydrology.
This assessment is intended to help conservation agencies, planners and organizations direct their resources to the most important places for supporting the ecoregion's biodiversity.

The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

Organophosphate insecticides may produce sublethal, adverse effects on salmonid
growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an
organophosphate insecticide, was detected by the Oregon Department of Environmental
Quality in the Hood River and tributaries during March 1999 at levels exceeding state
water quality standards in the range of 0.011-0.482 μg/L....
Thesis summarizes interviews with growers residing within the Groundwater Management Area (GWMA) in the Southern Willamette Valley of Oregon. Informal and semi-structured interviews were used to identify perceived impediments and incentives perceived by local farmers in following best management practices related to water quality. Results from the interviews were coded...
Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

This study examined the juvenile marine science collections of ten public libraries on the Oregon coast to assess if they adequately provided children with good science books about their backyards. While most of the libraries demonstrate a strong commitment to children's services, none has evaluated their juvenile collections beyond monitoring...
The presence and significance of salmon for prehistoric and aboriginal people of the Columbia Plateau is a matter of considerable debate among anthropologists, archaeologists and historians. Data from over 100 archaeological sites are scrutinized in the light of an example salmon fishery developed from ethnographic and archaeological information on aboriginal...

This study compares and evaluates wheat acreage responses among production systems in Oregon and Washington and between this region and estimated national average wheat acreage response. Oregon and Washington are disaggregated into five regions each on the basis of general similarity in soil, climate, substitute crops and production structures. Regional...

The Seventh Annual James A. Vomocil Water Quality Conference was planned after three topics had been selected as being of particular interest. Wetlands, Best Management Practices, and Riparian Zone Effectiveness were the topics. Speakers were invited who by virtue of their training, their experience, or their work assignment had insights...
"This report is organized as follows. First, the
objectives and methods used are outlined. Background
information follows, including what is known about the
extent, past alterations, and condition of wetlands in
Oregon today; the status of wetland restoration in the U.S.
and in Oregon; definitions of important terms; the functions...
An attempt was made to predict western spruce budworm defoliation using
egg counts from plots in the Douglas-fir type east of the Continental
Divide in Montana, the Douglas-fir type west of the Continental Divide
in Montana, and the mixed grand fir Douglas-fir type of northern Idaho.
The parameters used in...
Western spruce budworm defoliated area in the Northern Region has differed significantly across three discrete geographic zones during the past decade. Aerially visible defoliation in northern Idaho increased from 1.7 million acres in 1969 to a high of 2.2 million acres in 1974, and declined to none in 1979. Defoliated...
The microbial insecticide, Bacillus thuringensis (Bt), was applied from fixed-wing aircraft to approximately 700 acres of western spruce budworm host type at the rate of 12 billion international units (BIU's) per gallon of water per acre. The objective of this control project was foliage protection to insure future cone production...
