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...

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...

Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...

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...

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...

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...
