These fields have low plant species diversity and lack the shrubs and forbs lo support strong populations of pronghorn antelope (Antilocapra americana), greater sage grouse (Centrocercus
urophasianus) and Baird's sparrow (Ammodramus bairdii) as well as many other species compared to native grasslands or sagebrush steppe (Reynolds and Trost, 1980; Urness, 1986; Rotder et al., 2015).

(5) For example, state and federal partnerships with private landowners in 11 western states (Oregon, Washington, California (northern), Nevada, Idaho, Montana, Wyoming, Colorado, Utah, North and South Dakota) are aimed at helping keep the greater sage-grouse (Centrocercus
urophasianus), from being federally listed under the Endangered Species Act (ESA), consistent with the decision in 2015.
For example, Sage Grouse (Centrocercus
urophasianus) is strongly associated with sagebrush (Artemesia tridentata), Chukar (Alectoris chukar) is associated with cheatgrass (Bromus tectorum), and Chestnut-backed Chickadees (Parus rufescens) appears to follow the distribution of Douglas-fir (Pseudotsuga menziesii) in California .
West Nile virus (WNV) spread to the US western plains states in 2003, when a significant mortality event attributed to WNV occurred in greater sage-grouse (Centrocercus
Presettlement distribution of sage-grouse (Centrocercus
spp.) in New Mexico is poorly known (Bailey, 1928; Ligon, 1961) and was generally depicted by Schroeder et al.
A second concern is that sagebrush is slow to recover following fire and consequently available forage, nesting and brooding habitat for sage grouse (Centrocercus
urophasianus) are negatively affected (Baker 2006; Meinke et al.
(2009) modeled the potential for sage grouse (Centrocercus
urophasianus) leks to be lost as a result of different levels of predicted oil and gas development.
Increases in corvid abundance are often correlated with declines in their prey (Lauro and Tanacredi 2002; Kelly and others 2005; Webb and Marzluff 2007; Klausen and others 2010), especially threatened and endangered taxa such as the Desert Tortoise (Gopherus agassizii; Kristan and Boarman 2003), Marbled Murrelet (Brachyramphus marmoratus; Peery and Henry 2010), Greater Sage-Grouse (Centrocercus
urophasianus-, Coates and others 2008), and the California Least Tern (Sterna antillarum browni; Caffrey 1995).
