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: The influence of harvest management and fertilizer application on seasonal yield, crude protein concentration and N offtake of grasses in northeast Saskatchewan: Journal: Canadian Journal of Plant Science; Authors: D. H. McCartney, S. Bittman, and W. F. Nuttall; Date: 2004; Summary: In Saskatchewan, McCartney et al. compared annual and seasonal productivity, protein concentration, and N offtake by several adapted grasses as influenced by harvest management and fertilizer application in the central Aspen Parkland. Meadow bromegrass (Bromus riparius) had both high yield and relatively uniform seasonal production, making it a desirable grass for pastures in the central Parkland region. It also offered the most late-season yield. The high yield of green needlegrass (Nassella viridula) under multiple harvests suggests that this gras ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Fall cattle grazing versus mowing to increase big-game forage: Journal: Wildlife Society Bulletin; Authors: N. Taylor, J. E. Knight, and J. J. Short; Date: 2004; Summary: Taylor et al. found that mowing, at a moderate utilization level (50%), in the fall can leave more grass, as well as total biomass for elk and deer the following spring. Cattle grazing at a 90% utilization level can also leave more grass and biomass, but the authors urged that it can have an adverse effects on vegetation in the long run. Overall, mowing and grazing at the 70% utilization level did not seem to have any effect on total biomass. ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: A comparison of soil chemical characteristics in modified rangeland communities: Journal: Journal of Range Management; Authors: J. F. Dormaar, and W. D.

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 ...

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 ...

Title: WEPP and GLEAMS simulations of runoff and soil loss from grazed pasture in the southeastern United States

Journal: Journal of Environmental Science and Health. Part A: Toxic/Hazardous Substances and Environmental Engineering

Authors: W. E. Pitts, K. H. Yoo, M. S. Miller-Goodman, W. L. de los Santos, and K. S. Yoon

Date: 1999

Summary: Predicted values of surface runoff and erosion from two current erosion models (WEPP and GLEAMS) were compared to observed data recorded during January (1995) to August (1996) from the Tennessee Valley region of Alabama. Twelve runoff plots were located in three forage types (common bermudagrass, tall fescue, and switchgrass) under two grazing practices (proper grazing (recommended) and heavy grazing). Proper grazing stubble heights of bermudagrass, tall fescue, and switchgrass were 10, 15, and 20 cm respectively. Heavy grazing stubble heights were half of proper grazing. Runoff was collected ...

Title: Plant response to defoliation in a subalpine green fescue community

Journal: Journal of Range Management

Authors: S. H. Sharrow, and D. E. Kuntz

Date: 1999

Summary: Sharrow and Kuntz measured the level of elk (Cervus canadensis) grazing on three subalpine green fescue (Festuca viridula) meadows in Mt. Rainier National Park, and simulated grazing at different intensities (25, 50, 75%) and times during the growing season (early, mid, late). Elk utilization of forage in subalpine meadows was very low during the two years of the study. Less than half of the green fescue plants showed signs of browsing and only about 10% of the phytomass was removed on the majority of grazed plants, indicating that concerns about inc ...

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 ...

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 ...

Title: Grazing impacts on bulk density and soil strength in the foothills fescue grasslands of Alberta, Canada

Journal: Canadian Journal of Soil Science

Authors: D. S. Chanasyk, and M. A. Naeth

Date: 1995

Summary: Chanasyk and Naeth quantified grazing effects on soil bulk density and soil strength of sloped areas in the Alberta foothills fescue grasslands. They measured the effects of two grazing intensities (heavy and severe) under two treatments (short duration and continuous) compared to an ungrazed control. Soil properties were related to precipitation levels and in general, severe and continuous grazing tended to have greater impacts than heavy and short duration grazing. Soil bulk density and penetration resistance were greatest in continuous severely grazed pastures and lowest in short duratio ...

Title: Grazing effects on soil water in Alberta foothills fescue grasslands

Journal: Journal of Range Management

Authors: M. A. Naeth, and D. S. Chanasyk

Date: 1995

Summary: Naeth and Chanasyk measured surface soil water, soil water at a depth of 50 cm, and evapotranspiration in grasslands exposed to no grazing, heavy, or severe grazing for one week in June (short duration) or continuously grazed from May to October. Surface soil water was lowest in ungrazed pastures and highest in the severe, short duration treatment; whereas soil water at a depth of 50 cm was greatest in ungrazed plots and lowest in severe, continuously grazed plots. Evapotranspiration was lowest in the continuous, severely grazed treatment and highest in the short duration, heavily grazed tre ...
