Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

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,...

The Influence of Cow Age on Botanical Composition of Diets in Mixed Conifer Mountain Riparian Areas and Adjacent Uplands

Creator:: Darambazar, Enkhjargal, DelCurto, Timothy, Ackerman, Callan, Damiran, Daalkhaijav, and Morrison, Julie
Abstract:: The objective of this study was to evaluate the effect of cow age on botanical composition of diets in mountain riparian areas. Treatments consisted of 30 first calf heifers, and 30 mature cows randomly assigned to four pastures (2 pastures/treatment, average 21.5 ha) in a two-year study with a cross...

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...

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...

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...

Influence of previous cattle and elk grazing on the subsequent quality and quantity of diets for cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav, DelCurto, Timothy, Findholt, Scott, Pulsipher, Gary, and Johnson, Bruce
Abstract:: A study was conducted to determine foraging efficiency of cattle, mule deer, and elk in response to previous grazing by elk and cattle. Four enclosures, in previously logged mixed conifer (Abies grandis) rangelands were chosen, and within each enclosure, three 0.75 ha pastures were either: 1) ungrazed, 2) grazed by...

Estimating Shrub Forage Yield and Utilization Using a Photographic Technique

Creator:: Damiran, Daalkhaijav, DelCurto, Timothy, Johnson, Douglas, Findholt, Scott, and Johnson, Bruce
Abstract:: We assessed a photographic technique to estimate shrub yield and utilization of common snowberry, snowbrush, and heart-leafed willow found in mixed-conifer rangelands. We determined the correlation between green leaf area size (LA) and forage yield (Y) and compared plant utilization estimated by photographic technique (ULA) to actual utilization (UY) values....

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...
