Understory vegetation response and nitrogen cycling following cutting of western juniper

Creator:: Bates, Jonathan D.
Abstract:: Since the late 1880's western juniper has expanded in range and increased in density in sagebrush-bunchgrass, riparian, and forested plant communities of the Pacific Northwest. Succession to western juniper woodland has been shown to reduce the productivity and diversity of the understory component, result in concentration of soil nutrients beneath...

A comparative assessment of four winter feeding programs for spring calving cow-calf ranches in the Harney Basin, Oregon

Creator:: Bates, Jonathan D.
Abstract:: The objective of this thesis is to assess four winter feeding programs of spring-calving brood cows that may improve profitability to ranching operations of the Harney Basin, Oregon. The four feeding strategies include strip grazed rake-bunched hay, supplemented range grazing, strip grazed meadow pasture, and baled hay feeding. These first...

Community analysis of the Wyoming big sagebrush alliance and functional role of Wyoming big sagebrush

Creator:: Davies, Kirk W.
Abstract:: This study consisted of two research projects in the Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh) alliance, the most extensive of the big sagebrush complex in the Intermountain West. In the first project, we intensively sampled 107 relatively undisturbed, late seral Wyoming big sagebrush...

Prescribed fire effects on vegetation and arthropod dynamics, and sampling techniques in a Wyoming big sagebrush community

Creator:: Rhodes, Edward C.
Abstract:: In the western United States, sagebrush (Artemisia spp L.) dominated rangelands are extensive, accounting for approximately 63 million ha. The Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young) alliance is found in more xeric environments, occupying the largest area of the big sagebrush complex in areas within...

Vegetation Response to Western Juniper Slash Treatments

Creator:: O’Connor, Casey, Miller, Rick, and Bates, Jonathan D.
Abstract:: The expansion of pion-juniper woodlands the past 100 years in the western United States has resulted in large scale efforts to kill trees and recover sagebrush steppe rangelands. It is important to evaluate vegetation recovery following woodland control to develop best management practices. In this study, we compared two fuel...

Local resilience, canola cropping, and biodiesel production

Creator:: Bates, Christopher Allen
Abstract:: New technology may have negative, as well as positive, effects on a sociocultural system. Biodiesel is growing in popularity as a fuel alternative that addresses global warming and reduces dependency on petroleum. The biodiesel innovation fits well into the existing behavioral infrastructure of Linn and Benton Counties, Oregon. The introduction...

Restoration of Mountain Big Sagebrush Steppe Following Prescribed Burning to Control Western Juniper

Creator:: Davies, K. W., Bates, Jonathan D., Madsen, M. D., and Nafus, A. M.
Abstract:: Western juniper (Juniperus occidentalis ssp. occidentalis Hook) encroachment into mountain big sagebrush (Artemisia tridentata spp. vaseyana (Rydb.) Beetle) steppe has reduced livestock forage production, increased erosion risk, and degraded sagebrush-associated wildlife habitat. Western juniper has been successfully controlled with partial cutting followed by prescribed burning the next fall, but the...

Mowing Wyoming Big Sagebrush Communities With Degraded Herbaceous Understories: Has a Threshold Been Crossed?

Creator:: Davies, Kirk W., Bates, Jonathan D., and Nafus, Aleta M.
Abstract:: Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) plant communities with degraded native herbaceous understories occupy vast expanses of the western United States. Restoring the native herbaceous understory in these communities is needed to provide higher-quality wildlife habitat, decrease the risk of exotic plant invasion,...

Is fire exclusion in mountain big sagebrush communities prudent? Soil nutrient, plant diversity and arthropod response to burning

Creator:: Davies, Kirk W., Bates, Jonathan D., Boyd, Chad S., and Nafus, Aleta M.
Abstract:: Fire has largely been excluded from many mountain big sagebrush communities. Managers are reluctant to reintroduce fire, especially in communities without significant conifer encroachment, because of the decline in sagebrush-associated wildlife. Given this management direction, a better understanding of fire exclusion and burning effects is needed. We compared burned to...
