Influence of range improvement practices on composition, production, and utilization of Artemisia deer winter range in central Oregon

Creator:: Urness, Philip J.
Abstract:: Recent emphasis on range improvement of sagebrush-bunch-grass types in Oregon has underscored the need for better understanding of their importance to deer winter range management. The objectives of this study were to evaluate the impact of various sagebrush control practices on the composition, production, and utilization of deer forage plants...

Genetic and stability relationships of four Western Cascade soils

Creator:: Paeth, Robert Carl, 1925-
Abstract:: A sequence of soils derived from tuffaceous rocks was sampled on the H. J. Andrews Experimental Forest and adjacent U. S. Plywood land to determine some genetic and stability relationships. The less than two micron size fraction from each sample was characterized by x-ray diffraction with respect to crystalline clay...

Vegetation and animal responses to grazing crested wheatgrass at three intensities and two seasons in southern Idaho

Creator:: Sharp, Lee Ajax
Abstract:: Land useable for livestock grazing in the western United States is diminishing because of spreading municipalities, irrigation developments, highway construction, recreational demands and withdrawals. Concurrently, the demand for livestock and livestock products is increasing because of a rapidly growing population. As a result, production from the grazing land that remains...

Effects of seeding and grazing on a clearcut-burn in a mixed-coniferous forest stand of the Wallowa mountain foothills

Creator:: Pettit, Russell Dean
Abstract:: Research was conducted in a mixed-coniferous forest stand that was clearcut, burned, and seeded in order to study early plant succession, grazing influences on native and introduced species, big game use, and environmental relationships vegetation, animal, and environmental research was carried out from 1965 to 1967 in three, five-acre exclosures...

Seasonal cattle and sheep diets on Festuca arundinacea-Trifolium subterraneum and Lolium perenne-Trifolium subterraneum pastures in western Oregon

Creator:: Bedell, Thomas E.
Abstract:: Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum) pastures in western Oregon during the spring and summer periods of 1964 and 1965. Esophageal-fistulated Willamette ewes and Hereford and Hereford-Angus yearling cattle were grazed separately on each pasture mixture...

Heritabilities and associations of seed yield components and seed yield in tall fescue (Festuca arundinacea, Schreb.)

Creator:: Thomas, Johnny Ray
Abstract:: Estimates of heritability and associations of tiller number, seed number, seed weight, and seed yield were determined in two groups of tall fescue. Group E was early maturing and had eight parental clones, while group I was intermediate in maturity and had nine parental clones. The parents and five progeny...
