Evaluation of Native Grass Sod for Stabilization of Steep Slopes: Author: Stone, Kenley Michelle; Date: 2005-05-15; Program: Land Rehabilitation; Abstract: The purpose of this investigation was to evaluate the ability of native grass sod to establish on several different steep slope environments. Specific objectives were to (i) measure plant growth characteristics on slopes with native grass sod treatments compared to other plant establishment methods, (ii) compare runoff, sediment yield, and infiltration rates on slopes with native grass sod to other plant establishment methods for a peak 10 year 24 hour storm event, (iii) model sediment yield on native grass sodded slopes compared to other plant establishment methods using RUSLE version 2.0, an...; Download File | View full details

Response of Grass Species to Soil Salt Content and Coversoil Depth on Lands Developed for Coalbed Methane: Author: Mitchem, Melissa Deanne; Date: 2005-08-15; Program: Land Rehabilitation; Abstract: In areas where land is disturbed to extract energy resources such as coalbed methane, improper soil management may result in soils impaired by elevated salinity. The objectives of this study were to evaluate the emergence and growth of three native grass species (Pseudorogeneria spicata, Hesperostipa comata, and Pascopyrum smithii) as a function of i) soil salt content and matric potential, and ii) coversoil depth overlying a saline substrate. The first study consisted of nine treatments, combining three soil salinity levels (0.80, 5.0 and 11.0 dS/m) and three matric potential ranges (-0.1 to ...; Download File | View full details

Reclamation potential of experimental oak mat and conventional natural gas drill pad construction techniques in a sagebrush steppe community: Author: McWilliams, Colin Shamus; Date: 2008-05-15; Program: Land Rehabilitation; Abstract: Conventional cut-and-fill drill pad construction associated with natural gas production displaces existing plant communities and results in surface disturbances requiring extensive soil remediation and revegetation. At the Jonah natural gas field, Wyoming, use of an oak mat drilling platform placed atop the intact landscape was evaluated to facilitate drilling while minimizing disturbances to soil and plant resources. Concerns inherent to both techniques include adverse, long-term impacts to vegetation communities, soil compaction and soil physical and chemical characteristics.
