Title: Assessment of Best Management Practice Effects on Rangeland Stream Water Quality Using Multivariate Statistical Techniques: Journal: Rangeland Ecology & Management; Authors: C. A. Ellison, Q. D. Skinner, and L. S. Hicks; Date: 2009; Summary: This study took place along Muddy Creek in south central WY. Water quality data were collected from 1994-2004 and analyzed to determine whether livestock grazing best management practices (BMPs) improved water quality of the watershed. Rain gauges, water quality monitoring stations, and stream cross sections were established. Water quality parameters measured were pH, electrical conductivity, total dissolved solids, dissolved oxygen, turbidity, and temperature. Physical attributes were elevation, slope, weighted mean substrate size, weighted embeddedness, stream velocity, and stream flow.

Title: Multi-scale landscape factors influencing stream water quality in the state of Oregon: Journal: Environmental Monitoring and Assessment; Authors: M. S. Nash, D. T. Heggem, D. Ebert, T. G. Wade, and R. K. Hall; Date: 2009; Summary: Surface water quality data were collected from 1990-1994 across the state of Oregon, including eastern arid lands with high desert prairie. Data were analyzed according to landscape metrics and a grazing potential index (GPI) based on proximity to water, land ownership and forage availability, to determine distribution and relationship of biotic (enterococci bacteria) and abiotic (nitrogen-N and phosphorus-P) for indication of animal presence and influence on water quality. Metrics included percentage forest, riparian, agriculture, manmade or natural barren, natural gras ...; Agrovoc Control Words: Grazing, Water Quality, Watershed; View more details about this article

Title: Spatial and temporal patterns of cattle feces deposition on rangeland: Journal: Journal of Range Management; Authors: K. W. Tate, E. R. Atwill, N. K. McDougald, and M. R. George; Date: 2003; Summary: Environmental and management factors associated with cattle feces deposition patterns across annual rangeland watersheds on the San Joaquin Experimental Range near Madera, CA (37Â° 6â€™ 8â€ N, 119Â° 43â€™ 33â€ W) were identified and modeled under year-long continuous cattle grazing. Four stocking rates (0.14, 0.16, 0.11, and 0.13 AU/ha per year) were examined over 4 years. Daily cattle fecal load accumulation rates were calculated from seasonal fecal loads. Slope, aspect, hydrologic position, surface rock cover, oak canopy cover, pres ...; Agrovoc Control Words: Rangelands, Watershed Management, Grazing; View more details about this article

Title: Erosional effects of cattle on streambanks in Tennessee, U.S.A.: Journal: Earth Surface Processes and Landforms; Authors: S. W. Trimble; Date: 1994; Summary: A six year, controlled study from June to February was conducted along Jenkins Creek, Tennessee to investigate morphological differences between ungrazed streambanks and those grazed in accordance with regional management practice. A perennial stream reach was divided into three sub-reaches; each sub-reach received one of three grazing treatments (control, grazed with unlimited stream access all season and a grazed channel pond). Mechanical erosion and bank scouring were measured. ...; Agrovoc Control Words: Watershed management, Grazing, Erosion; View more details about this article

Title: Potential for enhancing riparian habitats in the southwestern United States with watershed practices: Journal: Forest Ecology and Management; Authors: L. F. DeBano, and L. J. Schmidt; Date: 1990; Summary: This is a literature review of 40 published scientific articles covering potential enhancements to riparian habitats in headwater and downstream river environments with watershed practices in Southwest United States. ...; Agrovoc Control Words: Riparian zones, Rangelands, Watershed management; View more details about this article
