Oregon’s Protection from Fire Program is the largest program within the Oregon Department of Forestry (ODF). The program provides wildfire protection on about 15.8 million acres of mostly privately-owned Oregon forestland. Private and state interests in protecting Oregon forests from fire have been intertwined since the early 1900s when ODF...
This assessment outlines an enhanced planning approach for West Coast estuaries that incorporates an evaluation of the regional context for estuarine conservation and recommends an approach to site-scale planning with more focus on ecological processes and functions.
A contingent valuation methodology was applied to old-growth forests and critical habitat units for the Northern Spotted Owl in Oregon to esimate the economic value to the public in knowing that rare and unique ecosystems will be protected from fire for current and future generations. Generalizing to the whole state,...
The primary purpose of this Guide is to encourage private landowners to conserve, and when appropriate, actively manage Oregon white oaks that already exist on their property, and consider planting additional oaks. In the early chapters of the Guide, we describe some of the uses and benefits of this remarkable...
A study was undertaken in the fall of 1948 by the Oregon Fish Commission to determine the possible presence and importance of a delay in the migration of adult chinook salmon (Oncorhynchus tshawytscha) at Bonneville Dam on the Columbia River. Approximately 650 chinook were captured, tagged, and released at the...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...
A systematic review of evidence was conducted concerning the effects of large wood placement on salmonids. In contrast to a general literature review, a narrowly focused question was targeted. The question was formulated before the review commenced and specified the subject, treatment, and outcomes of interest. The primary review question...
The purpose of this project was to conduct a preliminary examination of the environmental use of plants in Oregon by gauging the breadth of opportunities and challenges faced by growers, users, and researchers who are involved in the general area of the environmental uses of plants. More specifically, the project...
The Biodiversity Monitoring Workgroup which consists of federal, state, university, NGO’s, and private landowner stakeholders who are involved in aspects of monitoring biodiversity in the states of Oregon and Washington—conceived of the idea of exploring the possibilities of creating a Regional Biodiversity Monitoring Partnership.
This report is a summarization of investigational work that has been completed since 1941 by the Oregon State Game Commission on the coast streams south of the Columbia River, exclusive of the Umqpua and its tributaries. The Umpqua river system was covered in another report prepared jointly by biologists of...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
Ages were determined for 65 fish from the 1947 run and for 287 fish from the 1949 run. In 1947 the percentage composition by age was as follows: 32.3 percent 3-year-old fish, 66.2 percent 4-year-old fish, and 1.5 percent 5-year-old fish. An approximate 95 percent confidence interval for the true...
Samples, consisting of scales, length and weight measurements, and sex determinations of chum, pink, and silver salmons, were taken from the commercial catch in the Columbia River in 1914. Five hundred eighteen chum scales were examined. All fish had gone to sea early in their first year; and 70.5 percent...
Workable log grading systems are needed as aids to marketing timber and other phases of forest management. How can on system be evaluated and compared with other systems. The question of comparisons arose soon after the Western Pine Section of the Forest Service's National Log Grade Project was established in...
In a paper now in press as a Bulletin of the U. S. Fish and Wildlife Services the writer has discussed the downward trend of the catch of Columbia River Chinook salmon since 1920 and has stated that the decline is doubtless an indication that the runs of this species...
The objective of the thesis is to present data upon which the management of the Oregon otter-trawl fishery can be based. In addition, a history of the Oregon trawl fishery is presented. A summary of gear development by many of the vessels in the Oregon fleet is presented in table...
Tillamook Bay chum salmon are caught commercially by gill-nets, both set and drift, and from 1928 through 1949 the landings have averaged 819,689 pounds per season. More chum salmon are caught on Tillamook Bay than on the rest of the Oregon coastal rivers combined. These fish enter the ocean only...
Trends in greater sage-grouse breeding populations are typically indexed by determining the peak number of males attending a lek in a lekking season. Numerous studies have estimated negative trends in sage-grouse breeding populations over time via data collected for the last 50 years. However, the inherent bias in data collection...
The Applegate Fire Plan is a collaborative effort, hatched from an idea that was developed jointly by local citizens and federal agency folks in the Spring of 2001. Due to wide-spread participation throughout the Applegate Valley, general project coordination was organized by the Applegate Partnership, a non-profit communitybased group founded...
The Arapaho Ranch is an interesting study regarding the relationship between good land stewardship and the implementation of the current CCX range protocol. The Arapaho Ranch appears to be a model of the ways in which sustainable rangeland management and economic diversification, including profitable niche marketing and payment for ecosystem...
Arsenic concentrations exceeding the U.S. Environmental Protection Agency (USEPA) current Maximum Contaminant Level (MCL) of 50 micrograms per liter are widespread in ground water in the Willamette Basin. The Oregon Water Resources Department and the U.S. Geological Survey began a cooperative study in the Willamette Basin in 1996. One goal...
