Title: Cattle grazing in a national forest greatly reduces nesting success in a ground-nesting sparrow: Journal: The Condor; Authors: G. E. Walsberg; Date: 2005; Summary: Walsberg studied the effect of cattle grazing on a small ground-nesting song bird in northwestern Arizona. The author located 17 nests in the cattle-grazed pasture and 21 nests in the ungrazed pasture. Only 2 of the 17 nests in the grazed area were successful in fledging young, while 10 of the 21 nests in the ungrazed area were successful. Pictures of each nest were taken with a hemispherical fisheye lens which produced a 180 degree view from the nest. In the ungrazed areas, 66% of nests had vegetation occluding the nest in the upper hemisphere, while 39% of the grazed area nests had veget ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Small mammals in montane wet meadow habitat at Grays Lake, Idaho: Journal: Northwest Science; Authors: J. E. Austin, W. H. Pyle; Date: 2004; Summary: Austin and Pyle looked at the habitat selection of small mammals in a montane wet meadow as effected by cattle grazing and fall burning on the Grays Lake National Wildlife Refuge in Idaho. All mammal populations fluctuated significantly between years; highest in 1998(pre-treatment) and lowest in 1999(first year of treatment). Yet, treatment or microhabitat has no significant effect on the capture rates of any species, which their were five looked at in total(montane vole Microtis montanus, meadow vole Microtis pennsylvanicus, vagrant shrew Sorexvagrans, ermine Mustela erminea and deer mouse ...; 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: Pairing season habitat selection by Montezuma quail in southeastern Arizona: Journal: Journal of Range Management; Authors: K. D. Bristow, and R. A. Ockenfels; Date: 2004; Summary: Bristow et al. looked at the effects of cattle grazing on the habitat selection of Montezuma quail in Arizona. The most important aspect of quail habitat was ample hiding cover followed closely by the presence of forbs such as yellow nutsedge (Cyperus esculentes) and Gray's woodsorrel (Oxalis grayi). The authors found no difference in numbers of quails encountered on moderately grazed coveys and those found in ungrazed coveys. In fact, moderate cattle grazing can increase the amount of forbs in an area which can improve the quail habitat. The autho ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Grazing management effects on plant species diversity in tallgrass prairie: Journal: Rangeland Ecology & Management; Authors: K. R. Hickman, D. C. Hartnett, R. C. Cochran, and C. E. Owensby; Date: 2004; Summary: A 6-year study was conducted in tallgrass prairie to assess the effects of grazing management on plant community composition and diversity. Native plant species diversity, species richness, and growth form diversity were significantly higher in grazed compared to ungrazed prairie, and diversity was greatest in the highest stocking density. There were no significant effects of grazing system on plant diversity, nor any significant stocking density x grazing system interactions, indicating that animal density is a key management variable influencing plant species diversity and composition in t ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
