Title: Finding solutions for bird restoration and livestock management: Comparing grazing exclusion levels: Journal: Ecological Applications; Authors: K. S. Nelson, E. M. Gray, and J. R. Evans; Date: 2011; Summary: The effects of complete and partial exclusion of cattle grazing on avian recovery was examined in a study conducted in riparian areas of Orestimba Creek and Garzas Creek on Simon Newman Ranch in foothills of San Joaquin Valley, CA. Avian data was collected during breeding season (April to June) from 2001-2006, from 05:00 to 11:00 hours in areas with full cattle-exclosures and seasonal exclosures. Observers noted individual birds by species and distance to each individual over a five-minute period at each station. Native species abundance and richness on each site were determined.

Fuhlendorf, W. R. Teague, K. M. Havistad, R. L. Gillen, A. J. Ash, and W. D. Willms; Date: 2008; Summary: This paper is a synthesis of 47 studies comparing continuous and rotational grazing from the AGRICOLA database and archived articles from Journal of Range Management. ...; Agrovoc Control Words: Rotational grazing, Continuous grazing, Grazing systems; View more details about this article

Title: Potential soil carbon sequestration in overgrazed grassland ecosystems: Journal: Global Biogeochemical Cycles; Authors: R. Conant, and K. Paustian; Date: 2002; Summary: Changes in grassland management that reverse the process of declining productivity can potentially lead to increased soil C. Therefore, rehabilitation of areas degraded by overgrazing can potentially sequester atmospheric C. Conant and Paustian modeled the potential for carbon sequestration in grasslands around the world, based on existing studies of soil fractions from heavily- and moderately-grazed locations. In general, more productive rangelands, such as those in the southeast, are better able to sequester carbon. Grazing regimes to increase productivity will increase the carbon conten ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Dynamic Optimal Management of Wind-Erosive Rangelands: Journal: American Journal of Agricultural Economics; Authors: D. Hu, R. Ready, and A. Pagoulatos; Date: 1997; Summary: A bioeconomic model was developed to analyze relationship between economically optimal and ecologically sustainable grazing practices for semi-arid wind-erosive rangelands (semi-arid perennial grasslands). The object of the model was to maximize social welfare, which they considered to consist of two aspects: 1) economic profit from livestock production and 2) loss from wind erosion. This was an expanse upon a previous model by adding dynamic interactions between grass growth and soil erosion then applied this model to Bashang province, China, to determine relationships between economically op ...; Agrovoc Control Words: Grazing, Bioeconomics, Economic analysis; View more details about this article

Title: Does short-duration grazing work in arid and semiarid regions?: Journal: Journal of Soil and Water Conservation; Authors: F. C. Bryant, B. E. Dahl, R. D. Petttit, and C. M. Britton; Date: 1989; Summary: In this review paper, Bryant et al. studied the effects of short-duration grazing systems on commercial ranches. Based on experiences of Texas Tech researchers of short-duration grazing systems compared with continuous, yearlong grazing, on sandy and sandy loam soils in semiarid climates, Bryant et al. have drawn some of the following conclusions: 1) short-duration grazing resulted in a decline in individual animal performance; 2) short-duration grazing did not improve diet quality of grazing animals; 3) doubt has been cast on the theory that short-duration grazing improves animal distributi ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Cattle foraging behavior in leafy spurge (Euphorbia esula) infested rangeland: Journal: Weed Technology; Authors: R. G. Lym, and D. R. Kirby; Date: 1987; Summary: Cattle foraging behavior was observed over three years on a 121 ha pasture near Leonard, North Dakota. Cattle were grazed season long at a heavy stocking rate (0.53 AUM/ha - 0.61 AUM/ha) in a pasture with four levels of leafy spurge infestation ranging from zero, low, moderate and high (0, 20 to 40, 40 to 60, and 60 to 80% leafy spurge). Herbage production and use were estimated for the four infestation classes. Density of leafy spurge was estimate annually. Mid- and end of season production and use of cool- and warm season grasses, forbs and leafy spurge were also estimated in each densit ...; Agrovoc Control Words: Weeds, Rangelands, Grazing; View more details about this article
