A broad range of factors influence wine grape quality and manipulation of these factors 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...
Inflorescence Necrosis (IN) has been an unpredictable problem for grape growers in Oregon. The
industry has seen significant losses due to this fruit set disorder in several out of the eight years since its
first description in 1988, particularly in Pinot noir. Little is known of how to prevent the...
For this trial, established Pinot noir vines, located on the valley floor of the Umpqua Valley in Oregon
were used. In 1996 and 1997 sixteen vines trained to the Scott Henry trellising system were separated
into four different quadrants, determined by shoot orientation: Bottom canopy, shoots trained toward the
ground;...
Grafted grapevines will become increasingly important in Oregon vineyards in order to prevent loss of plants to phylloxera infestations. Several rootstocks are now being evaluated in Oregon for horticultural traits and characteristics related to wine quality. Resistance or tolerance to other plant diseases affecting grapevines needs to be examined as...
The objectives of this study are to isolate and characterize pathogenic agrobacteria that cause crown gall in grapevines and test hot water dips as a method for eradicating the infectious bacteria . Crown gall is commonly found among Oregon vineyards and the causative agent, Agrobacterium vitis, is known to be...
This report and especially the accompanying Detail Files and MapFiles provide relatively detailed information on status, trends, distribution, limiting factors, and conservation needs of all of the Willamette’s wildlife species, listed plants, and vulnerable habitats. Data on habitat suitability for each species is provided by watershed (170 HUC6s), elevation (6...
This document partially addresses the Wetlands component of Island County’s Critical Areas Ordinance (CAO). It presents the results of a year-long collaborative project to compile, analyze, and summarize existing data pertinent to Island County wetlands. Similar in concept to the “report card” issued periodically for Puget Sound, this compilation attempts...
This document is primarily a review of Best Available Science applicable to Island County wetlands, as needed for categorizing wetlands for regulatory actions and determining widths for buffers (setbacks) that protect the functions of wetlands. The number of technical papers and reports published on these topics is enormous, and none...
We compiled existing data and information to characterize the condition and trends in high priority natural resources in Ebey’s Landing National Historical Reserve (EBLA, or "the Reserve"). We identified 29 indicators to evaluate seven major resource concerns. For each indicator we attempted to define reference conditions to which we could...
Contains ground-truthed wetland maps and scores representing ecosystem services of a large portion of the wetlands in Juneau, Alaska. LiDAR imagery was used extensively.
The Juneau Wetland Management Plan (JWMP), Volume 1, provides results of wetlands mapping and wetland functional assessments for currently undeveloped parcels within the City and Borough of Juneau (CBJ). The study areas were selected for their potential for future development based on low elevation and proximity to existing infrastructure. During...
Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...
Wetlands of the Colorado Plateau that receive water from irrigation can, by their functions, support several societal values. For example, their capacity for removing nitrate and perhaps pesticides from nonpoint source runoff might be considerable. However, relatively little research has been conducted in irrigated wetlands, and their ability to alter...
Because studies of forestry effects on wetlands have been so infrequent in the Pacific Northwest, each section in this report drew heavily from studies of forestry impacts to streams and riparian zones. After assembly and synthesis, that information was extrapolated, mostly in the form of hypotheses, to the very different...
This is an integrated assessment across terrestrial, freshwater, and coastal marine realms. It includes the coast range of Oregon and Washington as well as Vancouver Island in British Columbia. The marine portion only includes the coastline and shallow subtidal; the next iteration will include the offshore component.

The main research goal for this study was to describe how investment into the Hubs has influenced local STEM communities; that is, how STEM Hubs have begun to create opportunities for partnerships, collaboration, connected programing, improved program development or delivery, or improved communication within and outside the STEM teaching and...
Despite increasing consumer demand for organic food and farm products and double-digit annual sales growth, U.S. organic production is currently flat and unable to meet demand. This report presents findings from a national survey of farmers about their experiences with organic transition, exploring motivations, obstacles, and desired resources and support...
Under July 1, 1972 - June 30, 1973 cost levels for the Little White Salmon and Willard National Fish Hatcheries, small budget reductions made by reducing expenditures for fish food resulted in sharp increases in average total cost per pound of salmon produced.
Experiments were conducted to determine survival, growth, and accumulation of HEOD (major component of dieldrin) in the tissues of steelhead trout (Salmo gairdneri) embryos, alevins, and fry exposed to dieldrin concentrations ranging from 0.012 to 52 ppb. The fish were held in specially designed exposure chambers provided with continuously renewed...

The primary purpose of this pest management guide is to provide fruit growers with up-to-date information on registered pesticide uses considered to be effective for controlling insect pests, mite pests, and diseases, when applied at the listed rates and timings.
This document summarizes a large volume of information obtained during an assessment of the environmental resources and probable effects of operation and maintenance projects of the U.S. Army Corps of Engineers on those resources. Much of the information is contained in “Volume II: Operation and Maintenance of the Channels and...
Introduction- “This Volume… contains information accumulated during an environmental assessment of the Yaquina Estuary region. This information is the basis for many statements contained in the companion volume.” Companion Volume: Volume I: Draft Environmental Impact Statement Operation and Maintenance of the Channels and Breakwaters in Yaquina Bay and River, Oregon...
This report summarizes a study which sought to provide toxicity data for pulp mills near Coos Bay through a series of toxicity bioassays. The study also surveyed benthic and beach fauna to identify macro-organisms so individual assessments of water quality requirements could be made.
This report discusses data collected in the Yaquina Estuary from July 1976 through December 1977 at 6-8 week intervals. Also summarized are recording salinometer, runoff and precipitation data from September 1967 through July 1968. Station names and locations for the 76-77 field data are shown in Figure 1. Figure 2...
In July and August 1961, nine lots of 500 juvenile silver salmon each were subjected to one-, two-, three- and four-week periods of complete starvation. The three- and four-week periods produced the best growth checks for that time of year, but were generally of inferior quality to those produced in...
Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed in November, 2011...
