Title: Postfire succession in big sagebrush steppe with livestock grazing: Journal: Rangeland Ecology & Management; Authors: J. D. Bates, E. C. Rhodes, K. W. Davies, and R. Sharp; Date: 2009; Summary: The effects of cattle grazing on post-fire recovery of herbaceous vegetation were evaluated during 3 growing seasons between 2003 and 2005 in the Northern Great Basin Experimental Range, 34.8 miles west of Burns, Oregon (4593 feet altitude). The experiment was conducted in 5, 12.6-ha blocks where 6 treatments were applied in 2.1-ha plots for each block. The plots were burned in late Sept - early Oct 2002, killing 90% of the Wyoming big sagebrush. The treatments were grazing the first 2 summers after fire (Summer 1), grazing the 2nd and 3rd summer after fire (Summer 2), grazing the 2nd and 3rd ...; Agrovoc Control Words: Sagebrush, Grasses, Grazing; View more details about this article

Title: Defoliation effects on arbuscular mycorrhizae and plant growth of two native bunchgrasses and an invasive forb: Journal: Applied Soil Ecology; Authors: S. Z. Walling, and C. A. Zabinski; Date: 2006; Summary: Walling and Zabinski determined the effects of simulated herbivory on the growth and nutrient content of spotted knapweed, Idaho fescue and bluebunch wheatgrass plants, with or without arbuscular mycorrhizae. All plants that were clipped or had arbuscular mycorrhizae were smaller than plants not exposed to these treatments, suggesting that arbuscular mycorrhizae limited plant production instead of enhancing it. Clipping enhanced N and P concentrations and arbuscular mycorrhizae enhanced plant N concentrations. However, since biomass of these plants was lower, the total plant N and P content ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Long term grazing effects on genetic variation in Idaho fescue: Journal: Rangeland Ecology & Management; Authors: D. Matlaga, and K. Karoly; Date: 2004; Summary: Previous research indicated that long-term grazing altered the physiological characteristics of Idaho fescue (Festuca idahoensis) plants at the Northern Great Basin Experimental Range, and the authors of this study suspected that these changes resulted from genetic differences between grazed and ungrazed populations. Therefore, the genetic variation of plant populations were determined using inter-simple sequence repeat (ISSR) DNA markers from Idaho fescue populations inside and outside of a 64 year old grazing exclosure located at the site. Polymorphic loci and expected ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Livestock grazing effects on forage quality of elk winter range: Journal: Journal of Range Management; Authors: P. E. Clark, W. C. Krueger, L. D. Bryant, and D. R. Thomas; Date: 2000; Summary: The effects of late spring grazing on winter forage quality and quantity of bluebunch wheatgrass, Idaho fescue and elk sedge were assessed in 3 plant communities selected in 3 different locations (blocks) within the study area on the Spring Big Game Winter Range Management Area in the Blue Mountains, Oregon during 1993 and 1994. Each block contained two main plots, 250 m by 800 m each with similar proportion of each plant community (bunchgrass grassland, mixed-conifer forest and pine-bunchgrass savanna). Sheep grazing occurred in a rest-rotation system with one main plot grazed in the boot sta ...; Agrovoc Control Words: Wildlife, Rangelands, Grazing; View more details about this article

Title: Grass defoliation intensity, frequency, and season effects on spotted knapweed invasion: Journal: Journal of Range Management; Authors: J. S. Jacobs, and R. L. Sheley; Date: 1999; Summary: Density, cover and biomass of spotted knapweed was examined on Idaho fescue, bluebunch wheatgrass dominated sites in outside of Bozeman, Montana. This study was designed to examine the effects of grazing on spotted knapweed establishment. Idaho fescue plants within 1 m² plots were clipped at four levels (0, 30, 60 and 90% defoliation), two seasons (spring and summer) and three frequencies (1, 2 and 3 at 14-day interval) over a period of three years for a total of 24 treatments replicated 4 times at 2 sites classified as Idaho fescue and bluebunch wheatgrass habitat ty ...; Agrovoc Control Words: Weeds, Rangelands, Grazing; View more details about this article

Title: Length and timing of grazing of postburn productivity of two bunchgrasses in an Idaho experimental range: Journal: International Journal of Wildland Fire; Authors: S. C. Bunting, R. Robberecht, and G. E. Defosse; Date: 1998; Summary: The minimum length of the non-grazing period after fire and the effect of early and late grazing on plant productivity were assessed on 60 plants of Idaho fescue and bluebunch wheatgrass randomly selected and assigned to 6 experimental groups of 10 plants each. The study was located at the University of Idaho Experimental Forest, 32.3 miles northeast of Moscow, Idaho, on a south-facing slope. Half of these groups were burned with a field portable instrument used to simulate a natural grass fire. Treatments of non-defoliation, early-season (summer) and late-season (fall) defoliation were applie ...; Agrovoc Control Words: Wildfires, Grasses, Rangelands; View more details about this article

Title: Seasonal preferences of steers for prominent northern Great Basin grasses: Journal: Journal of Range Management; Authors: R. Cruz, and D. Ganskopp; Date: 1998; Summary: The relative preference of cattle across three phonological (vegetative, anthesis and quiescent) stages for 8 prominent northern Great Basin grasses (bluebunch wheatgrass, Idaho fescue, bottlebrush squirreltail, needle-and-thread grass, Sandberg\'s bluegrass, Thurber\'s needlegrass, giant wildrye, and \'Nordan\' crested wheatgrass) was assessed in experimental paddocks and rangeland pastures established on the Northern Great Basin Experimental Range near Burns, Oregon (4495 feet altitude). One hundred plants of each species were randomly replanted in 9 experimental paddocks, each containing a ...; Agrovoc Control Words: Rangelands, Grasses, Grazing; View more details about this article

Title: Gas exchange of Idaho fescue in response to defoliation and grazing history: Journal: Journal of Range Management; Authors: P. S. Doescher, T. J. Svejcar, and R. G. Jaindl; Date: 1997; Summary: Doescher et al. measured the effects of simulated herbivory on photosynthesis, water conductance, xylem potential and carbon isotope ratios of Idaho fescue (Festuca idahoensis) plants, removed from grazed or ungrazed pastures. All plants exposed to simulated herbivory during the study had greater photosynthesis and water conductance, which allowed plants to compensate for loss of photosynthetic area. Plants from grazed pastures had greater water conductance and carbon isotope ratios than plants taken from non-grazed pastures, indicating that plants with a history of graz ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Persistence of Idaho fescue on degraded rangelands: Adaptation to defoliation or tolerance: Journal: Journal of Range Management; Authors: R. G. Jaindl, P. Doescher, R. F. Miller, and L. E. Eddleman; Date: 1994; Summary: Authors hypothesized that these remnant native grass survivors have responded to livestock grazing, over the past 110 years, through development of genetically based ecotypes that are more tolerant of defoliation than populations protected from heavy use by domestic livestock. Transplanted individuals of a native grass, Idaho fescue (Festuca idahoensis), from heavily grazed and ungrazed rangelands were compared. Plants were clipped during the vegetative, boot, and anthesis stages in 1990 and 1991. Results showed that grazing history had no consistent effect on Idaho fes ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Responses of bluebunch wheatgrass, Idaho fescue, and nematodes to ungulate grazing in Yellowstone National Park: Journal: Oikos; Authors: E. H. Merrill, N. L. Stanton, and J. C. Hak; Date: 1994; Summary: In this study, Merrill et al. sampled above and belowground biomass of Idaho fescue (Festuca idahoensis) and bluebunch wheatgrass (Agropyron spicatum) plants, as well as nematode densities associated with these species, inside and outside a 2-year old exclosure on the northern range of Yellowstone National Park in 1990. Grazing during the winter and early spring removed essentially all the standing dead plant material. Indirect effects of grazing, such as the effects of removing standing dead material on microclimate conditions, likely influenced ear ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Effects of cattle grazing upon chemical constituents within important forages for elk: Journal: Northwest Science; Authors: W. J. Dragt, and K. M. Havstad; Date: 1987; Summary: The effect of summer cattle grazing on the winter forage quality of bluebunch wheatgrass, Idaho fescue and rough fescue for elk within the Elkhorn Mountains of Montana was investigated. Forage quality was determined by comparing utilization and chemical constituents in relation to eight grass phenological stages (vegetative, boot, emerging seed heads, anthesis mature flowers, seed shatter, mature foliage, and fall regrowth). Cattle were grazed in a conservatively stocked three pasture deferred-rotation system. Utilization was measured bi-weekly from June-October of one year. After winter ...; Agrovoc Control Words: Grasses, Rangelands, Wildlife; View more details about this article

Title: Growth and reproduction of grasses heavily grazed under rest-rotation management: Journal: Journal of Range Management; Authors: R. E. Eckert, and J. S. Spencer; Date: 1987; Summary: Authors determined basal area and frequency of occurrence of native grasses in three big sagebrush-grass communities in Nevada, following 3 years of heavy grazing in a 9-year, rest-rotation grazing system. Thurber needlegrass (Stipa thurberiana) decreased in the grazed plots and increased in the protected plots from 1977 to 1983, Idaho fescue (Festuca idahoensis) and squirreltail (Sitanion hystrix) increased in protected plots in the Wyoming big sagebrush-Idaho fescue (Artemisia tridentata wyomingensis-; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
