Title: Spring habitat requirements of captive-reared Attwater's prairie chicken: Journal: Rangeland Ecology & Management; Authors: M. A. Lockwood, M. E. Morrow, N. J. Silvy, and F. E. Smeins; Date: 2005; Summary: Loamy prairie and claypan prairie range sites were preferred by the pen-reared Attwater's prairie chickens (Tympanuchus cupido attwateri) with a cattle (Bos taurus) stocking rate of 1.96 AUM/ ha. The Reichardt Pasture, with a greater stocking rate of 4.5 AUM/ ha, was the only pasture used during the spring by the pen-reared prairie chickens. The prairie chickens avoided pastures that were not as grazed as the Reichardt Pasture. Prairie chicken use of an area was positively correlated with cattle stocking rate, due to those areas typically having low ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Herbage productivity and ungulate use of northeastern Nevada mountain meadows: Journal: Rangeland Ecology & Management; Authors: J. L. Beck, and J. M. Peek; Date: 2004; Summary: In this study, Beck and Peek determined the effects of elk (Cervus elaphus) use and cattle (Bos taurus) use on three mountain meadows in northeastern Nevada during different seasons through exclosure fencing and simulated grazing (clipping). In wildlife and control treatments, graminoids tended to increase over the grazing season, while declining in cattle-grazed pastures; indicating little vegetation use by wildlife. Forbs tended to decline over the grazing season, especially in cattle-grazed and heavily clipped pastures, during early- or mid-summer ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Observations of cattle use of prairie dog towns: Journal: Journal of Range Management; Authors: D. A. Guenther and J. K. Detling; Date: 2003; Summary: Guenther and Detling used vegetation measurements and observations of cattle activity and location to determine cattle use and preference of habitat types in grassland pastures that contained prairie dog (Cynomys ludovicianus) towns (up to 11% habitat composition). Intensive surveys indicated that cattle preferred swale habitat and that prairie dog towns were not preferred but were also not avoided. Vegetation at prairie dog towns was shorter than other habitat types but consisted of preferred species and cattle were observed grazing at a similar rate that they grazed on ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Niche partitioning among mule deer, elk, and cattle: do stable isotopes reflect dietary niche?: Journal: Ecoscience; Authors: K. M. Stewart, R. T. Bowyer, J. G. Kie, B. L. Dick, and M. Ben-David; Date: 2003; Summary: Stewart et al. examined the forage used, and its contents of isotopes of nitrogen (N) and carbon (C) by cattle, elk and mule deer on the Starkey Experimental Forest and Range in northeastern Oregon. Mule deer had the widest variety in diet, which consisted mainly of sedges, forbs and browse, while cattle were primarily grazers. Elk concentrated on forbs, while grasses and browse made up a significant part of their diet. Stewart el al. found a depletion of δ¹⁵N and an enrichment of δ¹³C in the feces of mule deer. The most obvio ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Brown-headed cowbird behavior and movements in relation to livestock grazing: Journal: Ecological Applications; Authors: C. B. Goguen, and N. E. Mathews; Date: 2001; Summary: Goguen and Mathews found a connection between cattle (Bos taurus) grazing and brown-headed cowbird (Molothrus ater) feeding behavior as well as diurnal patterns of a female cowbird's behavior within her breeding range. Overall, 98% of cowbird feeding activity took place with pastured or corralled livestock. Cowbirds fed closely behind cattle's mouth, fore feet, or hind feet to catch insects that were kicked up by the cattle. Pastures that cowbirds consistently used for feeding while cattle were present, were immediately abandoned once cattle were rem ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Conservation value of private lands for crested caracaras in Florida: Journal: Conservation Biology; Authors: J. L. Morrison, and S. R. Humphrey; Date: 2001; Summary: This study found that privately owned cattle ranches prove to be preferable habitat for the crested caracara (Caracara cheriway) in southcentral Florida. Compared to nesting pairs on lands managed as natural areas, those on cattle ranches began laying eggs earlier and, more often, attempted a second brood after fledging a first brood. All of the caracara home ranges contained improved pasture, which differed immensely from the habitat composition of random areas, suggesting that caracara home range establishment is not random. On private lands, breeding pairs attempted ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Comparative ecology of bison and cattle on mixed-grass prairie: Journal: Great Plains Research; Authors: A. A. Steuter, and L. Hidinger; Date: 1999; Summary: Based on their observations of cattle (Bos taurus) and bison (Bos bison) grazing on Nature Conservancy-owned reserves in three Great Plains states (Nebraska, South Dakota, and North Dakota), Steuter and Hidinger compare the varying impacts of cattle and bison, in terms of diet, habitat, production requirements, and landscape level impacts. Under Nature Conservancy management, bison graze year-round on landscapes also managed with fire, resulting in patches of uniformly short vegetation surrounded by tall standing crop biomass. On similar landscapes, ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Nesting birds and grazing cattle: Accommodating both on midwestern pastures: Journal: Studies in Avian Biology; Authors: S. A. Temple, B. M. Fevold, L. K. Paine, D. J. Undersander, and D. W. Sample; Date: 1999; Summary: Ungrazed grasslands were the most productive for bird numbers, while rotationally grazed pastures were the least productive. Cattle (Bos taurus) trampling and nest desertion after cattle had grazed the surrounding nesting cover were the leading reasons for nest failure. The authors suggest a "pro-bird" grassland management system consisting of twelve paddocks, the center four being set aside as a nesting season refuge for birds. The authors conclude that livestock needs can be accommodated for, while also working towards increased avian productivity on grassla ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Effects of habitat and invertebrate density on abundance and foraging behavior of brown-headed cowbirds: Journal: The Auk; Authors: D. L. Morris, and F. R. Thompson, III; Date: 1998; Summary: Brown-headed Cowbirds (Molothrus ater) predominately used short-grazed grasslands for foraging. This preference of habitat is associated with the high invertebrate densities in these areas. Cowbird flock sizes were larger in grazed grasslands and in feedlots than in ungrazed grasslands. Cowbirds chose to feed near cattle (Bos taurus) without preference of grass height. Feedlots had the lowest density and biomass of invertebrates, and the highest peck rates due to the increased availability of hayseed and grain. Overall, cattle proved to be an impo ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Grazing sheep and cattle together or separately: Effect on soils and plants: Journal: Agronomy Journal; Authors: A. O. Abaye, V. G. Allen, and J. P. Fontenot; Date: 1997; Summary: In this 3 year study, grazing sheep and cattle together tended to reduce the impacts of grazing on vegetation and soils, when compared to grazing either herbivore alone. Mixed species pastures had less forbs and more grass species, higher soil nutrient content and soil pH, and lower B-horizon soil bulk density than pastures grazed by sheep or cattle alone. Grazing sheep alone tended to increase the P content and bulk density of the soils, while reducing the amount of white clover in the pastures. Grazing cattle alone tended to reduce the amount of bluegrass and increase the amount of thistl ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Bighorn sheep response to ephemeral habitat fragmentation by cattle: Journal: Great Basin Naturalist; Authors: J. A. Bissonette, and M. J. Steinkamp; Date: 1996; Summary: California bighorn sheep (Ovis canadensis californiana) home range position shifted and range size was reduced when cattle (Bos taurus) were relocated into an allotment adjacent to sites with high sheep use. When cattle were moved into bighorn sheep core areas, distances moved by sheep increased by 355% compared to usual sheep movements (3,000 vs. 845 m, respectively). The mean distance between sheep and their escape terrain decreased as cattle and sheep were in closer proximity, suggesting that cattle are seen as a threat. Bighorn sheep newly reintroduced to the area were more sensitive to ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Ungulate grazing in sagebrush grassland: mechanisms of resource competition: Journal: Ecological Applications; Authors: N. T. Hobbs, D. L. Baker, G. D. Bear, and D. C. Bowden; Date: 1996; Summary: Three densities of elk (Cervus elaphus canadensis) were grazed in the winter and early spring to determine how each effected the availability and use of forage by cattle (Bos taurus) in the spring. Elk grazing removed live and dead plant biomass, reducing forage dry matter, digestible energy, and nitrogen available for cattle consumption. Average digestibility and nitrogen content of perennial grasses was improved due to elk grazing, resulting in a shift of dead to live forage available to cattle. For the conditions of this study, a 45 gm/m; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Dietary overlap among cattle and cervids in northern Idaho forests: Journal: Journal of Range Management; Authors: J. L. Kingery, J. C. Mosley, and K. C. Bordwell; Date: 1996; Summary: Kingery et al. looked at the possible interactions between cattle, elk and white-tailed deer through fecal analysis to determine the species composition. They found that elk and cattle were most likely to have overlapping diets within the grand fir habitat type. White-tailed deer and cattle were found to have no significant overlap in any of the five seral stages. The authors did find that in the red cedar habitat, elk and white-tailed deer had a notable overlap that was not expected. Another unexpected result in the red cedar habitat was that elk and cattle only displayed similar bite an ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Factors affecting Attwater's prairie-chicken decline on the Attwater Prairie Chicken National Wildlife Refuge: Journal: Wildlife Society Bulletin; Authors: M. E. Morrow, R. S. Adamcik, J. D. Friday, and L. B. McKinney; Date: 1996; Summary: Morrow et al. found that a combination of factors affect the Attwater's prairie-chicken (Tympanuchus cupido attwateri) population. Open areas, needed for prairie-chicken movement between clumps of grass where nesting occurs, were scarce, which could be a contributing factor to prairie-chicken declines. Inadequate grazing may have created this problem when cattle (Bos taurus) were removed from several pastures, leaving dense vegetation. Prairie-chicken population increases and declines were attributed not only to precipitation amounts and off-refuge ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Ungulate foraging areas on seasonal rangelands in northeastern Oregon: Journal: Journal of Range Management; Authors: D. P. Sheehy, and M. Varva; Date: 1996; Summary: Sheehy and Varva looked at the causes of spatial and temporal separation between elk, mule deer and cattle. They found that temporal separation was the most important factor for alleviating the encounters of wild ungulates and cattle. Spatial separation was a secondary factor contributing to the lack of encounters, especially between the three major ungulates in this study. Increased ungulate grazing could have the potential to increase conflict between elk and cattle because their dietary overlap is larger than that of elk and mule deer or mule deer and cattle. Overall, the amount of over ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
