Microhabitat selection of brood-rearing sites by greater sage-grouse in Carbon County, Wyoming

Creator:: Schreiber, Leslie A.
Abstract:: Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...

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...

Direct/Delayed Response Project: Definition of Soil Sampling Classes and Selection of Sampling Sites for the Northeast

Creator:: Lee, Jeffrey J., Marmorek, David R., Thornton, Kent W., Lammers, Duane A., and Stevens, Donald L.
Abstract:: The Direct/Delayed Response Project (DDRP) has been designed and implemented to estimate the number of lakes and streams that might become acidic in three regions due to current or altered levels of acidic deposition. As part of DDRP, 145 watersheds in the northeast US were mapped at 1:24,000 for soils,...

The Indian Dip Net Fishery at Celilo Falls on the Columbia River

Creator:: Schoning, Robert W., Merrell, Theodore R., Johnson, Donald R., and Oregon. Fish Commission
Abstract:: 1. The Indians at Celilo Falls catch an average of over 2,600,000 pounds of fish each year, in dip nets in a manner very much the same as used by their ancestors. 2. The bulk of the fish caught at Celilo Falls is from the upriver fall run of chinook...

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...

The effects on salmon populations of the partial elimination of fixed fishing gear on the Columbia River in 1935

Creator:: Johnson, Donald R., Chapman, Wilbert McLeod, 1910-1970, Schoning, Robert W., and Oregon. Fish Commission
Abstract:: 1. Six major types of commercial gear have been used to take salmon and steelhead on the Columbia River; namely, gill nets, set nets, seines, traps, fish wheels and dip nets. 2. The five important commercial species in the Columbia River are chinook, silver, blueback and chum salmon and steelhead...

Ecological baselines for Oregon's coast: a report for agencies that manage Oregon's coastal habitats for ecological and economic sustainability, and for all who are interested in the welfare of wildlife that inhabit our coast and its estuaries

Creator:: Hall, Roberta L., Ebert, Thomas A., Gilden, Jennifer S., Hatch, David R., Mrakovcich, Karina Lorenz, and Smith, Courtland L.
Abstract:: Against the backdrop of growing concern about dead zones, rare and endangered sea mammals, depletion of Oregon’s once‐abundant fish stocks, acidification threatening coastal molluscs, and proposals for marine reserves along Oregon’s coastline, a multidisciplinary group of scientists was called together in 2008 to discuss what is known about Oregon’s coastal...

Riparian and wetland vegetation of central and eastern Oregon

Creator:: Crowe, Elizabeth A. (Elizabeth Ann), 1963-, Kovalchik, Bernard L., Kerr, Marie Jeannette James, 1968-, Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: The structure and components of riparian areas influence the rate, amount, and timing of water, nutrients, organic debris, and inorganic materials that enter streams and rivers. The energy of floodwaters and their ultimate volume, timing and erosive power is influenced by the soils, vegetation and geomorphology of fluvial surfaces within...
