Warm, Winter Winds: Building a Case Study for the Oregon Coast Range

Creator:: Phillips, Briana
Abstract:: Warm, high pressure systems are measured from a weather station on a high elevation peak in the Oregon Coast range during the winter months. Temperature observations on Mary’s Peak show abnormally warm air in relation to the surrounding areas. The goal of this study was to characterize the frequency and...

Species diversity in understory vegetation of transitional forested rangelands in the Blue Mountains of Eastern Oregon

Creator:: Darambazar, Enkhjargal, Damiran, Daalkhaijav, DelCurto, Timothy, Riggs, Robert, Vavra, Martin, and Cook, John
Abstract:: The objective of this study was to quantify understory species diversity response to overstory manipulation of Blue Mountain eco-region forest. Forty nine ecological land units, including differing successional stages (sapling, pole, small saw, and saw log) and canopy cover (light and medium) in dry Grand Fir (Abies grandis), wet Grand...

Species Composition and Diversity on Northwestern Bunchgrass Prairie Rangelands

Creator:: Darambazar, Enkhjargal, DelCurto, Timothy, Damiran, Daalkhaijav, Clark, Abe, and Taylor, Robert
Abstract:: Management and conservation of rangelands are increasingly concerned with maintaining productivity, species composition, and diversity of native plant communities. We estimated aboveground annual productivity, species composition, and diversity of a native bunchgrass type community across 1152, 0.5 m2 plots at The Nature Conservancy’s Zumwalt Prairie Preserve in northeastern Oregon. Standing...

Exploring the library needs of resident graduate students at Oregon State University's Hatfield Marine Science Center: a report

Creator:: Gilmont, Susan
Abstract:: In an effort to ascertain the library needs of resident graduate students at a marine field station, a mailed survey and a focus group gathered student input. Respondents rated the current collection and services and identified areas needing improvement. A plan of action to improve services has been developed.

Botanical composition and diet quality of beef cattle grazing at three stocking rates following fuels reduction in mixed conifer forests

Creator:: Clark, Abe, DelCurto, Timothy, Vavra, Martin, Damiran, Daalkhaijav, and Darambazar, Enkhjargal
Abstract:: Due to the increasing cost and concern of catastrophic wildfires in the Western United States, there is an increasing interest in fuels reduction projects. Fuel reduction treatments utilize various methods of thinning and/or prescribed fire to obtain desirable forest stand conditions. However, the effects of fuels reduction on ecosystem function...

Visual Obstruction: Weight Technique for Estimating Production on Northwestern Bunchgrass Prairie Rangelands

Creator:: Damiran, Daalkhaijav, DelCurto, Timothy, Darambazar, Enkhjargal, Clark, Abe A., Kennedy, Patricia L., and Taylor, Robert
Abstract:: The estimation of standing crop is important in the management of rangeland resources. Direct measurements by clipping, drying, and weighing of herbaceous vegetation are time-consuming and labor-intensive. Therefore, non-destructive methods for efficiently and accurately estimating standing crop are needed in rangeland forage management. We assessed a visual obstruction (VO) technique...

Changes in Forage Quantity and Quality with Continued Cattle Grazing in a Mountain Riparian Pasture

Creator:: Darambazar, Enkhjargal, DelCurto, Timothy, Ackerman, Callan, Pulsipher, Gary, and Damiran, Daalkhaijav
Abstract:: The objective of this study was to evaluate changes in the quantity, quality, and moisture of available forage in a riparian pasture, and shrub utilization by cattle during a 30-d late summer grazing period. A riparian pasture (44.7 ha) in northeast of Oregon was grazed with 30 yearlings (419 kg,...

Diet composistion, dry matter intake, and diet overlap of mule deer, elk, and cattle

Creator:: Findholt, Scott, Johnson, Bruce, Damiran, Daalkhaijav, DelCurto, Timothy, and Kie, John
Abstract:: Mule deer (Odocoileus hemionus), elk (Cervus elaphus), and cattle share rangelands throughout much of interior western North America. Considerable debate exists about the degree to which facilitation or competition occurs for forage between these three species (Nelson 1982, Wisdom and Thomas 1996, Miller 2002). Prior cattle grazing can have beneficial...
