This report is an attempt to address some critical information gaps regarding the effects of dikes and tide gates on coastal ecosystems and fisheries resources. The authors have identified the information needs during their work with landowners, community organizations, and resource management agencies and through a compilation and summary of...
Pinot noir and Chardonnay are two of the major varieties grown in the cool climate region of the Pacific Northwest. In Oregon, Pinot noir comprised approximately 43 percent of the total acreage and approximately 6,800 were harvested in 2000. In previous years, Chardonnay (1,125 acres in 2000) had been the...
Extensive information on rootstock resistance to lime is available since it has been one of the major selection criteria in Europe an rootstock breeding programs. Information regarding the performance of rootstocks in acidic soils however, is not so prevalent. Differences in genotype tolerance to high acidity maybe related to different...
Progress Reports for projects: Audio/Visual instruction of canopy management for wine grapes in Oregon, Utilize the northwest berry and grape information network to communicate to Oregon wine grape growers on-farm experimentation techniques (on-line/on-farm), and Publishing of the 2003 pest management guide for wine grapes.
Vineyard acreage in Oregon continues to increase at a rapid pace. In the past two years alone 1600 acres of new vineyard land have been planted (Rowley et al., 2000). Much of this has been on phylloxera-resistant rootstocks. This practice is strongly encouraged, since it is the only practical way...
A broad range of factors influences wine grape quality and its manipulation has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends largely on...

In 1988 the Tualatin River was designated 'water quality limited' by the Oregon Department of Environmental Quality. Three sources of pollution: urban point source, forestry non-point source and agricultural non-point source pollution were considered to contribute unacceptable levels of nutrients (phosphates and ammonium nitrates) to the river. Since a significant...
