Standing in the Way of Control : Small Farmers, Water Use, and Technology Adoption in Oregon

Creator:: Hepperly, Jody R.
Abstract:: In recent years, several interrelated forces—prolonged drought, growing populations, height-ened environmental protections, sustained agricultural use, and hydrologic alterations due to climate change—have increased pressure on water users in the Western United States, where the agricultural sector accounts for up to 90% of total water withdrawals. Technology im-provements developed since the...

Potential effects of the invasive grass Ventenata dubia on elk habitat selection within the Starkey Experimental Forest and Range

Creator:: Crum, Keren-happuch R.
Abstract:: The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...

Effects of Biochar and Nitrogen-Enriched Soil Amendments on Plant Growth, Mineral Nutrition, and Early Fruit Production in Highbush Blueberry (Vaccinium sp.)

Creator:: Sales, Bryan K.
Abstract:: The goal of the work in this dissertation was to identify alternative soil amendments to improve plant growth and yield during establishment of highbush blueberry (Vaccinium hybrid). Woody materials, such as sawdust and wood chips, have a high carbon to nitrogen (C:N) ratio and low water holding capacity, which can...

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...

A GIS investigation of indigenous intensification of native food plants : humans as environmental variable in maxent habitat suitability modeling of Camassia in Oregon

Creator:: Elliott, Braden T.
Abstract:: This thesis merges the fields of Ecology and Anthropology by applying Habitat Suitability Modeling to the relationship between people and plants in the Pacific Northwest. In it, I create and optimize two Maxent habitat suitability models for camas (Camassia spp.) in Oregon. The first model describes the physical environment of...

Assisted Migration in the Colorado Subalpine Forest

Creator:: Najim, Tara
Abstract:: This capstone study reports on global warming-induced changes to the Colorado subalpine zone climate and disturbance regimes. It assesses the impacts of these changes upon the dominant subalpine tree species and summarizes future species distribution modeling for these and other nearby species potentially suitable for the future subalpine zone in...

Investments in people and technology : public participation in the remediation of Dian Lake in Yunnan, China

Creator:: Carson, Andrea L.
Abstract:: From the 1960s to 1990s, the water quality of Dian Lake (滇池), China's sixth largest freshwater lake located outside the capital of Yunnan Province, Kunming City, rapidly declined causing livelihood disruption, decreased water availability, and biodiversity loss. Despite significant investments in remediation efforts, only small water quality improvements have been...
