Effect of western juniper removal on ponderosa pine and associated understory vegetation

Creator:: Rose, Jeffrey A.
Abstract:: This research assessed the effect of western juniper (Junlperus occldentalls) removal on understory plant production and cover and ponderosa pine (Pinus ponderosa) growth and plant water status. A complete randomized block design, with four blocks and four treatments was established in the summer of 1984 near Prineville, Oregon. The four...

The thermal characteristics of hydrologically intact Type C and E streams in eastern Oregon

Creator:: Hopkins, Karl T.
Abstract:: Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...

The influence of environmental and physical factors on the thermal patterns of headwater streams

Creator:: Carr, Craig A.
Abstract:: A case study was performed in 2000 and 2001 to characterize the thermal pattern of four morphologically similar eastern Oregon streams and to identify the physical and environmental factors that expressed significant and functionally viable relationships with stream temperature (daily maximum, daily minimum and daily rate of heating). Stream and...

Understory competition for resources in Pinus ponderosa forests of northeastern Oregon

Creator:: Riegel, Gregg M.
Abstract:: The objective of this research was to determine which environmental resources, light, water, and nutrients, control understory plant production and composition in a Pinus ponderosa forest in northeastern Oregon. A split-plot experimental design, with three blocks, four treatments, and 44 plots, was established in the summer of 1985. Twenty plots...

Effects of environmental variables and grazing on planted willow (Salix boothii Dorn) cuttings

Creator:: Lowson, Katherine L.
Abstract:: The influence of streambank location and timing of herbivory on success of planted Booth's willow (Salix boothii Dorn) cuttings along a Rosgen C5-type stream in an eastern Oregon meadow was determined. Willow cuttings were planted on two morphological locations (i.e. point bar and floodplain) in May of 2002 and 2003....

Conditioning of northern Great Basin grasses with livestock grazing

Creator:: Aguilera, Lisa M.
Abstract:: Because forage quality of cool season grasses declines to sub-maintenance levels for ruminants late in the growing season in the northern Great Basin, there is a need to elevate protein levels and digestibility of grasses for both wild and domestic ruminants in late summer. Anderson and Scherzinger (1975) proposed using...

Quantification of vegetation diversity and variation on intact and degraded rangelands

Creator:: Dysart, Patricia L.
Abstract:: Vegetation diversity in the Wyoming big sagebrush/Thurber needlegrass (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young/Achnatherum thurberianum (Piper) Barkworth. syn. Stipa thurberiana Piper) plant association was studied across a condition class gradient in southeastern Oregon. All observable vascular plant species were counted during 6 seasons and 2 years and diversity...

Ecological effects of post-wildfire management activities (salvage-logging and grass-seeding) on vegetation composition, diversity, biomass, and growth and survival of Pinus ponderosa and Purshia tridentata

Creator:: Sexton, Timothy Ogden
Abstract:: Salvage-logging and artificial seeding of grass following wildfire are common practices in coniferous forests of the western United States, yet few studies have quantified the ecological effects of these post-fire activities. The effects of post-wildfire salvage-logging and grass-seeding on vegetation composition, aboveground biomass, and growth and survival of Pinus ponderosa...

Shrub reestablishment following fire in the mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) alliance

Creator:: Ziegenhagen, Lori L.
Abstract:: Currently, the of lack information on shrub reestablishment following fire and the wide variability in rates of recovery have lead to uncertainty in using prescribed burning as a management tool in the mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) alliance. This study examined the recovery of shrub...
