The Tualatin River in northwest Oregon has been designated as water quality limited by the Oregon Department of Environmental Quality. Restoration and enhancement of riparian areas to improve water quality is one task to be pursued by management agencies. This paper examines some of the potential costs and benefits of...
This is the fourth report on the Oregon Plan for Salmon and Watersheds. The first three reports focused on people – their
stories and their efforts to restore watershed health and recover listed fish species. While these earlier reports contained
what little information was available regarding the quantitative aspects of...
The report summarizes basin level accomplishments and investments related to water quality improvements, fish recovery, and watershed
health. The report also provides an overview of state agency actions
and recommendations to enhance the effectiveness of the Oregon
Plan.
The 2003-2005 Biennial Report Volume 2 is an executive summary of Oregon's assessment of the Oregon Coastal Coho Evolutionarily Significant Unit (ESU). The assessment provides a detailed analysis that will inform the pending federal decision on whether to list coho as "threatened" under the Endangered Species Act.

In the 1980s, resource managers were increasingly concerned about effects of timber harvest on ungulates in National Forests. Land and resource management plans incorporated restrictions on timber harvest to maintain cover for Rocky Mountain elk
(CeNus e/aphus ne/soni V. Bailey) and mule deer (Odocoileus hemionus hemionus RafinesqueJ, and habitat models...
I developed a priori hypotheses and used logistic regression to model Greater Sandhill
Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...
This paper will address Oregon's ability to regulate and manage its wetland resources as a means for protecting and enhancing salmon habitat. After identifying the importance of wetland environments the paper will look into OWRF to assess its effectiveness. Ultimately the paper will conclude that OWRF's design is an effective...
Oregon's watershed councils are local, non-regulatory, collaborative forums charged
with the recovery of endangered salmon and improving water quality under The Oregon Plan for Salmon and Watersheds. Private forest landowners, given their prominence is owning riparian areas, are central to success of these efforts. Using a statewide survey of watershed...
This annotated bibliography is a response to widespread interest in stream habitat improvement in the Pacific Northwest by land managers, governmental and nongovernmental organizations, and the lay public. Several guides to stream habitat improvement have been written in the past, but may not be easily accessible to people from diverse...
Twenty-one countersunk culverts in Oregon were inventoried to establish baseline information for the stream crossings so that subsequent resurveys can assess the long-term stability and functionality of the culvert design. A subset of the inventoried culverts was selected for detailed hydraulic measurements. The detailed velocity measurements were used to help...
