The influence of environmental attributes on temporal and structural dynamics of western juniper woodland development and associated fuel loading characteristics

Creator:: Johnson, Dustin D.
Abstract:: Since European American settlement of the Intermountain Region, dramatic changes in vegetation composition and structure have occurred in the sagebrush steppe ecosystem. Western juniper (Juniperus occidentalis spp. occidentalis Vasek), although indigenous to the Intermountain Region, has increased since the late 1800s. Considerable work has been done documenting juniper woodland expansion...

The impact of limited-access highways on agricultural land : national interstate route 5, Linn County, Oregon, a case study

Creator:: Schmidt, Robert Howard
Abstract:: This study examines the impact of the recently constructed limited- access highway, Interstate 5, on agricultural land in Linn County, Oregon. More specifically it scrutinizes the quality and quantity of the land relinquished to the highway right -of -way; the effects on field boundaries, connectivity, mobility, drainage, land use, miscellaneous...

Western juniper encroachment into aspen communities in the Northwest Great Basin

Creator:: Wall, Travis G.
Abstract:: In the Northwest Great Basin, aspen (Populus tremuloides) communities uniquely contribute to the biodiversity of a semi-arid, sagebrush-dominated landscape. In this same region, western juniper (Juniperus occidentalis) is encroaching into aspen stands. This study determined the timing, extent, and some of the effects of this expansion. Aspen stands below 2,133...

A quantitative survey of the fleas associated with the gray-tailed vole, Microtus canicaudus Miller

Creator:: Robbins, Richard George
Abstract:: A study of the population dynamics and ecology of the fleas associated with the gray-tailed vole, Microtus canicaudus Miller, was conducted on three sites surrounding the city of Corvallis, Oregon. Over a period of 12 months, 22,641 adult and larval fleas representing three families and eight species were recovered from...

Response of Artemisia tridentata ssp. wyomingensis and Stipa thurberiana to nitrogen amendments

Creator:: Wang, Chien-kuo
Abstract:: The effect of nitrogen on influencing the competitive balance between a shrub, Artemisia tridentata ssp. wyolningensis (ARTRW) and a perennial grass Stipa thurberiana (STTH) in a sagebrush steppe community was determined. Nitrogen levels were altered on 5x5 in plots by applying 4.5 gun2 of nitrogen in the form of ammonium...

Seed bank response to juniper expansion in the semi-arid lands of Oregon, USA

Creator:: Duncan, Corinne M.
Abstract:: Expansion of Juniperus occidentalis into the sagebrush steppe has resulted in significant changes in understory composition. A consequence of increased J. occidentalis dominance may be a depletion of the seed bank. The potential for depletion is problematic because a reduction in the amount of species available from the seed bank...

Effects of environmental conditions on germination and early seedling development in Agropyron spicatum

Creator:: Evenden, Angela G.
Abstract:: This research evaluated the germination and early seedling development response of two sources of bluebunch wheatgrass (Agropyron spicatum) to a wide range of environmental conditions. Seeds collected near John Day, Oregon and Secar seed obtained from the Soil Conservation Service were used in the investigations. Evaluation of the germination response...

Soil and understory vegetation characteristics of a tractor-logged forest in eastern Oregon

Creator:: Snider, Michael Duane
Abstract:: A 1.5 ha mixed conifer stand in the Blue Mountains of Oregon was intensively examined to assess the impact of logging disturbance on soils and herbaceous vegetation. Sampling was conducted six years after much of the timber overstory was removed in a shelterwood cut and yarded by crawler tractor. A...

Effect of site potential, season and plant part on the quality and yield of cereal aftermath

Creator:: Mee, Catherine
Abstract:: The objectives of this study were to evaluate the effects of site potential, season and plant part on percent crude protein, percent digestibility of dry matter and yield of cereal residues. Three cereal types, club wheat (Triticum aestivum) tall, bearded wheat (T. aestivum), and barley Hordeum vulgare) were examined. Stress...
