Interspace/under-canopy foraging patterns of beef cattle in sagebrush communities : implications to sage-grouse nesting habitat

Creator:: France, Kevin A.
Abstract:: Livestock grazing has been indirectly related to sage-grouse (centrocercus urophasianus) declines in the western United States and southern Canada; however, there is a lack of scientific research that directly relates the two. Our objective was to investigate the influence of livestock herbivory on sage-grouse nesting habitat by determining the spatial...

Habitat use and selection by sage grouse broods in southeastern Oregon

Creator:: Drut, Martin S.
Abstract:: In Oregon, sage grouse (Centrocercus urophasianus) were common in the eastern portion of the state. Since 1940 populations declined because of decreased productivity. The western subspecies (C. u. phaios) was listed as a candidate for threatened and endangered status in 1985 because of declines in Oregon and Washington and extirpation...

Use and selection of nesting habitat by sage grouse in Oregon

Creator:: Gregg, Michael A.
Abstract:: Sage grouse (Centrocercus urophasianus) populations in Oregon declined during the past 30 years as a result of impaired productivity. The western subspecies (C. u. phaios) was listed as a candidate for threatened and endangered status by the Department of the Interior in 1985 because of declines in Oregon and Washington...

Linking greater sage-grouse habitat use and suitability across spatiotemporal scales in central Oregon

Creator:: Freese, Mark T.
Abstract:: Greater Sage-grouse (Centrocercus urophasianus) habitat research has historically focused on fine-scale (0.007 - 0.032 ha) vegetation structure and composition immediately surrounding sites selected by birds. However, little work has evaluated vegetation attributes important for Greater Sage-grouse at a landscape-scale or identified landscape attributes that influence habitat use patterns. Habitat use...

Greater sage-grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R.
Abstract:: Greater sage-grouse (Centrocercus urophasianus), a sagebrush obligate species, has contracted in extent by nearly half its original distribution. This is primarily due to habitat loss and degradation over the past 150 years. During winter, sage-grouse depend completely on sagebrush habitat for food and cover, yet sage-grouse winter ecology has been...

Response of brood-rearing habitat of sage grouse to prescribed burning in Oregon

Creator:: Pyle, William H. (William Hanson), 1957-
Abstract:: Decline of western sage grouse (Centrocercus urophasianus phaios) in Oregon may be related to the reduced availability of foods in upland sagebrush (Artemisia)-grasslands used for brood-rearing. The goal of this study was to determine primary foods of chicks and the short-term response of brood-rearing habitat to prescribed burning at Hart...

Placement of felled western juniper trees over a stream channel : Effects on water temperature, streamside willow shrubs, and redband trout

Creator:: Matney, Casey A.
Abstract:: All streams in Oregon that are inhabited by salmon and trout have a statemandated water temperature standard. However, temperatures of many streams, especially during summer months, exceed the seven-day average maximum temperature parameter (200 C for redband trout inhabited streams) accepted by the Oregon Department of Environmental Quality. To date,...

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...

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...

Breeding season habitat use and response to management activities by greater sage-grouse on Sheldon National Wildlife Refuge, Nevada

Creator:: Davis, Dawn M.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) have experienced declines throughout their range over the last 50 years. Long-term declines in sage-grouse abundance in Nevada and Oregon have been attributed to reduced productivity. From 1995-1997, sage-grouse production on Sheldon National Wildlife Refuge (SNWR), Nevada was greater compared to Hart Mountain National Antelope Refuge...
