A field study of the sage grouse in southeastern Oregon with special reference to reproduction and survival

Creator:: Nelson, Otto Christian
Abstract:: This thesis presents the information collected on various phases of the life history of the sage grouse in the Hart Mountain area of southeastern Oregon during the period of April 8 to September 12, l954. The material was gathered in an attempt to compile information on reproduction, survival, and other...

Emergence, survival and reproduction of three species of forbs important to sage grouse nutrition in response to fire, microsite and method of establishment

Creator:: Wirth, Troy A.
Abstract:: Since settlement of the Intermountain West, sage grouse abundance and productivity has declined and their range has decreased. The decline of sage grouse populations is primarily due to permanent loss and degradation of sagebrush-grassland habitat. Recently, several studies have shown that sage grouse productivity may be limited by the availability...

Diet and nutrition of female sage grouse during the pre-laying period

Creator:: Barnett, Jenny K.
Abstract:: Nutrition effects productivity of grouse. Females that obtain high nutrient diets in spring produce larger clutches and larger, more viable chicks than hens on less nutritious diets. Grouse select high nutrient foods to help ensure proper nutrition. Reduced productivity accounted for the decline of sage grouse (Centrocercus urophasianus) populations in...

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...

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...

The Impacts of Juniper Removal on Native Herbaceous Vegetation and Surface-Dwelling Invertebrates in the Sagebrush Steppe

Creator:: Haab, Kimberly A.
Abstract:: Understanding the effects of disturbance and restoration on a species’ habitat is essential for understanding the demographic rates and population trends observed in a species. Sufficient habitat provides the space and resources required for survival and successful reproduction, such as food availability, access to water, protection from predators, protection from...

Influence of habitat characteristics on Greater sage-grouse reproductive success in the Montana Mountains, Nevada

Creator:: Rebholz, James L.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations have declined across their geographic range during the last century. They were once widespread throughout the Intermountain West, but lower annual productivity, likely caused by degradation and loss of suitable habitat, has greatly reduced their distribution and population densities. Habitat used for reproduction has been...

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...
