Spring 2012
This study examined the potential of using conifer seedlings Picea glauca and Pinus banksiana inoculated with ectomycorrhizal (ECM) fungi to improve revegetation success and plant establishment in reclaimed oil sands mining sites. Mycorrhizal inoculum potential of the reclamation soils was low...

Influence of Soil Cap Depth and Vegetation on Reclamation of Phosphogypsum Stacks in Fort Saskatchewan, Alberta
DownloadSpring 2013
This study quantified environmental parameters to develop reclamation strategies for phosphogypsum stacks. Research was conducted on phosphogypsum stack experimental plots established in 2006 (6 soil cap depths, 5 vegetation treatments), and soil capped slopes seeded in 1998. Significant root...

Industrial development is transforming Alberta's landscapes, with largely unquantified effects on wildlife species. Open-pit mining is occurring on vast expanses, most notably for bitumen but also extensively for coal in a rich seam that traverses the province. Major concerns have developed over...

Drilling fluid, also referred to as drilling mud, is used to lubricate and cool the drilling apparatus, transport drill cuttings to the surface and seal off porous geologic formations. Disposal of drilling fluid is a growing concern to the global oil and gas industry as it can require extensive...

Spring 2013
A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...

Evaluating trembling aspen (Populus tremuloides Michx.) seedling stock characteristics in response to drought and out-planting on a reclamation site
DownloadFall 2014
Trembling aspen (Populus tremuloides Michx.) seedlings often display reduced growth, or transplant shock, following out-planting largely due to moisture constraints. This thesis explores the influence of seedling size (root volume), root to stem ratio (RSR) and non-structural carbohydrate (NSC)...

Fall 2014
This thesis explores the influence of non-structural carbohydrates (NSC), seedling size, and root:shoot ratio (RSR) on jack pine (Pinus banksiana Lamb.) seedling performance under different drought intensities in a growth chamber and after outplanting on a reclamation site. NSC content, size, and...
