Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Nutritional Management of Beef Cows During Late-Gestation to Enhance Offspring Productivity

Creator:: Marques, Rodrigo Da Silva
Abstract:: Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...

Physiological, Chemical and Genetic Studies in Meadowfoam (Limnanthes alba)

Creator:: Zhang, Jun
Abstract:: Meadowfoam (Limnanthes alba) is an oilseed crop with unique chemical characteristics. The ability to identify physiological maturity (PM) and harvest maturity HM of the crop would permit timely harvest of high quality seeds. However, changes of oil contents, fatty acid profile and glucosinolate contents, as well as seed quality during...

Ungulates and Forest Management : Understanding Interactions Between Large Herbivores and Fuels Reduction Treatments on Shrub Assemblages in the Intermountain West

Creator:: Hall Defrees, Dallas K.
Abstract:: Deciduous shrubs are an integral component of mixed conifer forests of the interior Pacific Northwest by providing structural complexity, forage, and niche habitat. Currently, these species are under pressure from high levels of ungulate herbivory and forest management activities such as fuels reduction treatments. Ungulate herbivory is influential in the...

New Environmental Governance on the Range : Voluntary Conservation to Preclude an Endangered Species Act Listing?

Creator:: Wollstein, Katherine L.
Abstract:: Natural resource challenges in the American West feature a suite of actors and processes operating at different spatial and political scales, and crossing several administrative jurisdictions. I applied concepts of new environmental governance to Oregon’s greater sage-grouse (Centrocercus urophasianus) conservation strategy, focusing, in particular, on features of voluntary conservation arrangements...

The Ecological Recovery of Saguaro National Park after Removal of Cattle Grazing and Associated Succession

Creator:: Summers, Ryan J.
Abstract:: In the area that is now Saguaro National Park East, grazing began in the 1880's. Because of the impact to the iconic saguaro cactus as well as all palatable plant species in the area, ecological damage in the park were determined to be so great that anti-grazing conservationists challenged the...

Activated carbon incorporated into herbicide protection pods as a seed amendment technology for revegetation

Creator:: Clenet, Danielle R.
Abstract:: Reestablishing native perennial vegetation in annual grass-invaded rangelands is critical to restoring ecosystems, especially following wildfires. Controlling invasive annual grasses is essential to increasing revegetation success; however, pre-emergent herbicides used to control annual grasses prohibit immediate seeding due to non-target herbicide damage. Thus, seeding is often delayed one year following...

Tackifier Type and Concentration have Varying Impacts on Growth of Dryland Mosses

Creator:: Blankenship, Wyatt D.
Abstract:: There is growing interest in using biocrusts (assemblages of cyanobacteria, lichens, mosses, and other taxa in various proportions covering the upper few millimeters of the soil surface) to assist in restoring ecosystem function and native plant communities in dryland ecosystems. Biocrusts can be transplanted and established using jute or thatch,...

Long-term Ecohydrologic Response to Western Juniper (Juniperus occidentalis) Control in Semiarid Watersheds of Central Oregon : A Paired Watershed Study

Creator:: Ray, Grace L.
Abstract:: Rangelands span over 50% of the globe and approximately 70% of the United States. Although livestock production is an important use of rangelands, the benefits of rangelands are highly diverse. Humans find intrinsic value in protecting these unique and variable landscapes for wildlife, vegetation, and recreation enthusiasts. Woodland plant encroachment...

Effects of oil and natural gas development on territory occupancy of ferruginous hawks and golden eagles in Wyoming, USA

Creator:: Wallace, Zachary P.
Abstract:: Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...
