Survival and nest site characteristics of translocated mountain quail on Steens Mountain, Oregon

Creator:: Nelson, Jamie N.
Abstract:: Mountain Quail (Oreortyx pictus) populations have declined in the eastern portion of their range during the last century. However, few studies have investigated the nesting habitat and survival of Mountain Quail translocated into an area from which they have been extirpated. We translocated 217 wild Mountain Quail (Oreortyx pictus) from...

Habitat parameters associated with the distribution of seven willow species on a stream in southeastern Oregon

Creator:: Gilbert, Griffith J.
Abstract:: Thirteen different habitat parameters were measured either quantitatively or qualitatively around seven different Salix (willow) species on a defined reach of stream on the southwestern slope of Steens Mountain in southeastern Oregon in order to both broaden the current information base of riparian ecology and inform future willow plantings aimed...

The effects of burning in mountain big sagebrush on key sage grouse habitat characteristics in southeastern Oregon

Creator:: McDowell, Michelle K. D.
Abstract:: Sage grouse are a species of concern because their abundance, distribution, and productivity have declined during the past century. Sage grouse productivity has been linked to specific habitat components including particular forbs and native bunchgrasses. Studies on the effects of fire were conducted in Southeastern Oregon in mountain big sagebrush...

Geology and petrologic evolution of the silicic to intermediate volcanic rocks underneath Steens Mountain basalt, SE Oregon

Creator:: Langer, Vera W.
Abstract:: Steens Mountain in SE Oregon is part of the northern Basin and Range Province, and represents a horst tilted about 100 to the west that is bounded to the east by a high angle, NNE trending normal fault. The minimum displacement is about 1200 m. Volcanic rocks, exposed along the...

The volcanic stratigraphy of the Mickey Hot Springs area, Harney County, Oregon

Creator:: Hook, Richard
Abstract:: Steens Mountain is a major horst block near the northern terminus of the Basin and Range geomorphic province of southeastern Oregon. A section of Miocene volcanic rocks totaling 5000 feet in thickness are exposed in a fault escarpment on the eastern side of Steens Nountain. These include: the Pike Creek...

Avian communities in relation to habitat influenced by fire in a sagebrush steppe landscape

Creator:: Noson, Anna C.
Abstract:: Fire suppression in high-elevation sagebrush steppe over the last century has profoundly influenced the structure and complexity of vegetation communities. Although fire is the primary management tool used to restore these areas, the impact of this management practice on associated avian communities is poorly understood. We examined patterns of habitat...

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...

Resource Selection, and Demographic Rates of Female Greater Sage-Grouse Following Large-Scale Wildfire

Creator:: Foster, Lee
Abstract:: Understanding the effects of habitat disturbance on a species' habitat selection patterns, and demographic rates, is essential to projecting the trajectories of populations affected by disturbance, as well as for determining the appropriate conservation actions needed to maintain those populations. Greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern...

Juvenile survival and birth-site selection of Rocky Mountain elk in northeastern Oregon

Creator:: Rearden, Spencer N.
Abstract:: With declining populations and low calf recruitment in northeastern Oregon, much interest has been generated to study the survival rates and causes of mortality of Rocky Mountain elk (Cervus elaphus nelsoni). I investigated the causes of elk calf mortality and the effects of predation risk on birth-site selection by cow...
