Greater Sage-Grouse Brood Responses To Livestock Grazing In Sagebrush Rangelands, Hailey Peatross Wayment
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The distribution and abundance of the greater sage-grouse (Centrocercus urophasianus; sage-grouse) have declined in the last 60 years. Range contractions and population declines have been attributed to loss and fragmentation of their sagebrush (Artemisia spp.) habitats. Grazing by livestock remains the predominant anthropogenic land-use across sagebrush ecosystems in North America, occurring on 87% of remaining sage-grouse habitat. Most of the peer-reviewed literature reports the potential for negative impacts of sagebrush reduction treatments, to increase livestock forage, on sage-grouse habitat. However, few studies have linked livestock grazing at the landscape level to vital rates (e.g., nest initiation rates, …
Influences Of Grazing On Habitat Characteristics, Avian Community Composition And Nesting Bird Abundance Within Cheyenne Bottoms, Ks, Kirsten Granstrom-Arndt
Influences Of Grazing On Habitat Characteristics, Avian Community Composition And Nesting Bird Abundance Within Cheyenne Bottoms, Ks, Kirsten Granstrom-Arndt
Master's Theses
Cheyenne Bottoms is a 41,000-acre prairie-marsh ecosystem in central Kansas. Approximately 8,000 acres of mixed grassland are dedicated for the conservation of bird populations, but little is known about the status of bird communities within these areas. This study took place within grassland areas of Cheyenne Bottoms from May – July 2021. I investigated bird community composition, relative abundance of frequently observed bird species, vegetative characteristics, and similarity of sites across different grazing intensities (continuous, rotational, and non-grazed). The four most common bird species observed were dickcissel (Spiza americana), grasshopper sparrow (Ammodramus savannarum), meadowlark species ( …
