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...
