Marine wetland boundary definition : evaluation of methodology

Creator:: Eilers, H. Peter, Taylor, Alan, Sanville, William, and Corvallis Environmental Research Laboratory
Abstract:: With legislation to protect wetlands and current pressures to convert them to other uses, it is often necessary to accurately determine a wetland-upland boundary. We investigated 6 methods to establish such a boundary based on vegetation. Each method was applied to a common data set obtained from 295 quadrats along...

A measured delay in the migration of adult chinook salmon at Bonneville Dam on the Columbia River

Creator:: Schoning, Robert W., Johnson, Donald R., and Oregon. Fish Commission
Abstract:: 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...

Some factors influencing the trends of salmon populations in Oregon

Creator:: McKernan, Donald L. (Donald Lynn), 1918-1979, Johnson, Donald R., Hodges, John I., and Oregon. Fish Commission
Abstract:: Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...
