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...

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...

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...
