“…The Greater Sage-Grouse (Centrocercus urophasianus; hereafter Sage-Grouse) is an herbivorous tetraonine with a specialized diet of sagebrush (Artemisia spp.) leaves from late autumn through early spring (Wallestad et al 1975). Sagebrush foliage contains relatively high concentrations of PSMs (e.g., monoterpenes, sesquiterpene lactones, phenolics; Kelsey et al 1982) and previous work has suggested that Sage-Grouse browse sagebrush selectively with respect to nutrients and PSMs (Remington andBraun 1985, Welch et al 1988).…”

Abstract. Animal habitat selection is a process that functions at multiple, hierarchically structured spatial scales. Thus multi-scale analyses should be the basis for inferences about factors driving the habitat selection process. Vertebrate herbivores forage selectively on the basis of phytochemistry, but few studies have investigated the influence of selective foraging (i.e., fine-scale habitat selection) on habitat selection at larger scales. We tested the hypothesis that phytochemistry is integral to the habitat selection process for vertebrate herbivores. We predicted that habitats selected at three spatial scales would be characterized by higher nutrient concentrations and lower concentrations of plant secondary metabolites (PSMs) than unused habitats. We used the Greater Sage-Grouse (Centrocercus urophasianus), an avian herbivore with a seasonally specialized diet of sagebrush, to test our hypothesis. Sage-Grouse selected a habitat type (black sagebrush, Artemisia nova) with lower PSM concentrations than the alternative (Wyoming big sagebrush, A. tridentata wyomingensis). Within black sagebrush habitat, Sage-Grouse selected patches and individual plants within those patches that were higher in nutrient concentrations and lower in PSM concentrations than those not used. Our results provide the first evidence for multi-scale habitat selection by an avian herbivore on the basis of phytochemistry, and they suggest that phytochemistry may be a fundamental driver of habitat selection for vertebrate herbivores.

“…Sage-grouse require sagebrush throughout the entire year. Sagebrush comprised 62 percent of the year-long diet of adult sage grouse and essentially 100 percent of their winter diet in Montana (Wallestad, Peterson, & Eng 1975). Sage-grouse require a variety of shrubs in different quantities for wintering, breeding, nesting, and brood-rearing (Connelly, Schroeder, Sands & Braun 2000, Crawford et al 2004).…”

“…During the winter, sage-grouse commonly use medium to tall sagebrush communities on south and west facing slopes (Connelly, Schroeder, Sands & Braun 2000), as well as sagebrush habitats with 12 (Woodward 2006) to 20 percent canopy cover in Montana (Wallestad et al 1975). Sage-grouse used areas with 1.2 shrubs/m2 in central Montana (Woodward 2006).…”

Greater sage-grouse (Centrocercus urophasianus) is a high priority species for federal and Environmental Management and Sustainable Development ISSN 2164-7682 2016 www.macrothink.org/emsd 130 state land management agencies in the Western United States. Sage-grouse are sagebrush (Artemisia spp.) obligates requiring sagebrush for their survival throughout the year. Sagebrush has been removed and replaced with crested wheatgrass (Agropyron cristatum & A. desertorum) throughout the West. The objectives of this paper were to review the literature (100 papers), as well as consult experts, to determine which methods are most likely to eliminate crested wheatgrass and establish sagebrush. No technique eliminates crested wheatgrass in a single application but research suggests it should not comprise more than 14% cover for successful reseeding of other species. Grazing and fire have no long-term impacts on crested wheatgrass. Mechanical treatments, such as plowing, disking, and cultivating reduce and eradicate crested wheatgrass, but a flush of invasive annual grasses following mechanical disturbance can make establishment of seeded species difficult. If invasive plant establishment is a problem with mechanical treatments, crested wheatgrass stands should be treated with glyphosate in early spring for two consecutive years at a rate of 1.1 kg/ha of active ingredient. Then, sagebrush should be seeded in the late fall using a compact row seeder or Brillion cultipacker at a rate of 0.22 kg/ha pure live seed.

“…In addition, 1 ,200 ha were proposed to be sprayed during early spring 1990. Before this spraying program, concern was raised over the impact of this herbicide program on other species of forbs, which are major spring and summer foods of sage grouse (Wallestad, Peterson, and Eng 1975). The purpose of this survey was to help identify the impacts on forbs of the proposed 1990 aerial spraying program.…”
