“…During 2004 sampling, individuals of big sagebrush averaged 6.66 cm in height. The open canopy available in the more shallow topsoil replacement areas accounted for germination and growth of shrubs at least three years after seeding (Owens and Norton, 1989;Williams et al, 2002). Comparison of Reclaimed Treatments to Older Reclaimed Area at NARM The oldest shrub-grassland reclaimed area at NARM, seeded with the mixture outlined in Table 1, was seeded in 1991; replacement topsoil depth in this area was 56 cm, but source of the replacement topsoil was direct-hauled not stockpiled as in the current study.…”

Abstract. After passage of the Surface Coal Mine Reclamation Act in 1977, studies on mine reclaimed areas in the late 1970's and early 1980's evaluated varying topsoil depths over unsuitable backfill on vegetation productivity and cover. In recent years, several of those earlier studies have been revisited to provide long-term results on vegetation productivity, cover and diversity. A more recent study developed in 1999 was conducted to evaluate variable topsoil depth on soil and vegetation factors at the North Antelope/Rochelle Mine (NARM). Backfill at this location did not exhibit unsuitable plant growth parameters, based on Wyoming Department of Environmental Quality (WDEQ) guidelines. The formal study evaluated vegetation parameters such as cover, production and diversity, and soil differences in pH, electrical conductivity (EC), and sodium adsorption ratio (SAR) between three treatment depths, i.e., 15, 30 and 56 cm. Reclaimed and two native vegetation reference areas were sampled three times during the 2000-2002 growing seasons. At the end of the 2002 monitoring, results were mixed. After that time, the reclaimed area only continued to be part of the ongoing vegetation monitoring program at NARM. Five years of continuous monitoring (2000)(2001)(2002)(2003)(2004) were statistically analyzed to determine significant trends between topsoil depth treatments, as the seeded areas matured. No significant differences were found between treatments for two measures of cover and three measures of species richness. Although no significant differences were found between treatments for shrub density, positive increasing trends in the more shallow treatments are evident.Additional Key Words: vegetation cover, shrub density, plant diversity, topsoil treatment depth.

“…According to the Wyoming State Rules and Regulations (2017), variable soil depths are also allowable: ''Soil thickness may also be varied to the extent such variations help meet the specific revegetation goals identified in the permit.'' Some studies performed in the western USA showed that revegetation results can be affected by varying soil depths (Buchanan et al 2005;Bowen et al 2005;Williams et al 2002). To enhance the growth of hard-to-establish shrubs such as big sagebrush (Artemisia tridentata), NARM has developed two soil replacement depth ranges: typical (15-40 cm) and deep (40-120 cm).…”

Surface coal mine permit application for successful reclamation, semi-arid shortgrass prairie (Wyoming, USA)

Approximately 40% of USA coal originates in an ecologically sensitive area of semi-arid shortgrass prairie in Wyoming. Before a surface coal mine can begin operation in the USA, it must secure a mining permit and comply with regulations and performance standards under the USA Surface Mining Control and Reclamation Act (SMCRA), other federal environmental acts, and state programs. The Wyoming Department of Environmental Quality (WDEQ)/Land Quality Division (LQD) administers Wyoming's coal regulatory program. The permit application and bonding process for the largest surface coal mine permit in the USA, North Antelope Rochelle Mine (NARM) located in short grassland prairie in the northeast Wyoming, is discussed. The permit application process begins with the collection of baseline environmental data that characterizes premining conditions of the permit area. The permit application includes adjudication information, baseline information, mine and operation plans, and reclamation plans. Fulfillment of permit commitments and requirements of rules and regulations are inspected monthly by the LQD's representative in the field. Before a mine permit is issued, the mine operator must submit a reclamation bond to secure the performance of reclamation obligations that is later revised annually. In Wyoming, four reclamation bond release phases indicate the completion of various stages of the reclamatikon process. NARM's specific bond release verification cirteria, performance standards, and field verificatoins of bond release phases are discussed. The Bond Release Geodatabase (a GIS/GPS approach) was developed for this mine to monitor progress in meeting criteria and performance standards for incremental bond release. The Bond Release Geodatabase significantly reduces the time needed to track bond release progress, reach agreement between operator and regulator, and improve the state inspector's ability to assess reclamation adequacy and progress.

“…On a mine reclamation project in Wyoming, sagebrush seed was broadcast seeded using a precision broadcast seeder with cracked corn to accomplish uniform seed distribution and flow through the seeder. Seeding rates between 1 to 4 kg/ha PLS were used and had sagebrush establishment densities of 1.0 to 4.5 shrubs/m2 after 6 years (Williams, Schuman, Hild & Vicklund 2002).…”

Greater sage-grouse (Centrocercus urophasianus) is a high priority species for federal and Environmental Management and Sustainable Development ISSN 2164-7682 2016 www.macrothink.org/emsd 130 state land management agencies in the Western United States. Sage-grouse are sagebrush (Artemisia spp.) obligates requiring sagebrush for their survival throughout the year. Sagebrush has been removed and replaced with crested wheatgrass (Agropyron cristatum & A. desertorum) throughout the West. The objectives of this paper were to review the literature (100 papers), as well as consult experts, to determine which methods are most likely to eliminate crested wheatgrass and establish sagebrush. No technique eliminates crested wheatgrass in a single application but research suggests it should not comprise more than 14% cover for successful reseeding of other species. Grazing and fire have no long-term impacts on crested wheatgrass. Mechanical treatments, such as plowing, disking, and cultivating reduce and eradicate crested wheatgrass, but a flush of invasive annual grasses following mechanical disturbance can make establishment of seeded species difficult. If invasive plant establishment is a problem with mechanical treatments, crested wheatgrass stands should be treated with glyphosate in early spring for two consecutive years at a rate of 1.1 kg/ha of active ingredient. Then, sagebrush should be seeded in the late fall using a compact row seeder or Brillion cultipacker at a rate of 0.22 kg/ha pure live seed.
