Abstract

Post-mining revegetation efforts often require grass seeding and mulch applications to stabilize the soils at the same time as shrub seeding, creating intraspecific competition between seeded shrubs and grasses that is not well understood. In 1999, we initiated a study at the Belle Ayr Coal Mine near Gillette, Wyoming, to evaluate the influence of grass competition on establishment and growth of Wyoming big sagebrush. Combinations of three sagebrush seeding rates (1, 2, and 4 kg pls ha{sup -1}) and seven cool-season perennial grass mixture seeding rates (0, 2, 4, 6, 8, 10, and 14 kg pls ha{sup -1}) were seeded during winter 1998-1999. Shrub density and grass cover were assessed from 1999 to 2004. We monitored sagebrush canopy size in 2001, 2002, and 2004. All sagebrush seeding rates provided shrub densities (>=) 1 shrub m {sup -1} after six growing seasons. Grass production (>=) 75 g m{sup -2} was achieved by seeding grasses at 6 to 8 kg pls ha{sup -1}). Canopy growth of individual sagebrush plants was least in the heaviest grass seeding rate. Reduced grass seeding rates can aid in achieving Wyoming big sagebrush density standards and enhance shrub canopy growth.

W-519 Sagebrush Mitigation Project FY-2004 Final Review and Status

Technical Report Durham, Robin; Sackschewsky, Michael

This report summarizes activities conducted as mitigation for loss of sagebrush-steppe habitats due to Project W-519, the construction of the infrastructure for the Tank Waste Remediation System Vitrification Plant. The focus of this report is to provide a review and final status of mitigation actions performed through FY2004. Data collected since FY1999 have been included where appropriate. The Mitigation Action Plan (MAP) for Project W-519 prescribed three general actions to be performed as mitigation for the disturbance of approximately 40 ha (100 acres) of mature sagebrush-steppe habitat. These actions included: (1) transplanting approximately 130,000 sagebrush seedlings on the Fitzner-Eberhardt Aridmore »« less

Evaluation of cultural methods for establishing Wyoming big sagebrush on mined lands

Conference Cockrell, J; Schuman, G; Booth, D

Wyoming big sagebrush (Artemisia tridentata spp. wyomingensis) is one of the most widely distributed and adapted shrub species in Wyoming and the region. However, its reestablishment on mined lands has proven difficult because of low seedling vigor, its inability to compete with herbaceous species, poor seed quality, and altered edaphic conditions. Field research evaluating the effect of topsoil management, mulching practice, and plant competition have shown that all of these factors significantly influence early initial sagebrush establishment. Greater sagebrush establishment occurred on fresh topsoil compared to 5 year old stockpiled topsoil. Stubble and surface applied mulch and elimination of herbaceousmore »« less
Establishing Artemisia tridentata ssp wyomingensis on mined lands: Science and economics

Journal Article Schuman, G; Vicklund, L; Belden, S - Arid Land Research and Management

In 1996, the Wyoming Department of Environmental Quality enacted regulations governing the reestablishment of woody shrubs on mined lands. The regulation required that an average density of one shrub m{sup -2} be reestablished on at least 20% of the disturbed land area and that the shrub composition must include dominant premine species. In Wyoming, and much of the Northern Great Plains, that meant that Artemisia tridentata Nutt. ssp. wyomingensis (Beetle and Young) (Wyoming big sagebrush) had to be reestablished on mined lands. Artemisia tridentata Nutt. ssp. wyomingensis had proven difficult to reestablish on mined lands because of poor quality seed,more »« less

Rapid restoration of functional plant communities on sites intensively disturbed by oil shale development

Thesis/Dissertation Koehler, D

Soils and subsoils in a sagebrush community of the Piceance Basin of northwestern Colorado were thoroughly mixed to a 1 m depth. Four treatments were applied to subplots constructed on this medium including (1) supplemental water applied to one-half the subplots at weekly intervals for two growing seasons, (2) three seeding mixtures including 16-18 species of either native, introduced or combination grasses, forbs and shrubs, (3) four seeding techniques designed to enhance the establishment of one or more life forms and (4) no fertilization or fertilization consisting of applications of 112 kg N and 90 kg P/ha.

Effect of municipal sewage sludge application on growth of two reclamation shrub species in copper mine spoils

Journal Article Sabey, B; Webb, B; Pendleton, R

One-year old transplants of fourwing saltbush (Atriplex canescens (Pursh) Nutt.) and mountain big sagebrush (Artemisia tridentata ssp. vaseyana (Rybd.) Beetle) were grown for 9 mo in large greenhouse pots containing copper mine spiol material amended with one of three rates of municipal sewage sludge. Sludge was thoroughly mixed with the soils in some pots and concentrated around the root plug in others. Additionally, some pots were seeded with western wheatgrass (Agropyron smithii Rydb.) to determine whether the presence of grasses would affect shrub response to sludge addition in low pH copper mine spoils. Growth of fourwing saltbush was enhanced frommore »« less
