Spring 2014
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...

Early Stages Of Calcareous Soil Reclamation Along The TMX-Anchor Loop Pipeline In Jasper National Park
DownloadFall 2010
Research assessed early stages of calcareous soil reclamation along the TMX-Anchor Loop pipeline through Jasper National Park. Calcareous soils are low in nutrients and highly prone to erosion after disturbances. Four sites were established in each of five calcareous soils, and divided into three...

Re-establishment of appropriate vegetation communities is an important aspect of successful forest reclamation as they contribute to various ecosystem functions. In my research I explore how different coversoil materials (salvaged forest floor (FFM) and peat material), their placement depths, and...

Effects of Biochar, Fertilizer and Shelter Treatments on the Vegetation Development following Coal Mine Reclamation
DownloadFall 2016
Poor quality cover soil, a lack of propagules, and availability of suitable microsites can be serious challenges in the re-vegetation success of surface mines. In my thesis research, I examined the response of total cover, species richness and community composition of colonizing vegetation on a...

Effects of Surface Contamination and Water Chemistry on the Behaviors of Illite, Kaolinite and Montmorillonite in Organic and Aqueous Media
DownloadSpring 2016
Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Clays, in tailings, are a significant ongoing environmental concern in the mining and oil sands production industries and clay...

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...

This research aims to improve oil sands tailings treatment by applying a combination of quick lime (calcium oxide) and anionic or cationic polymers in the flocculation process. A procedure including mixing lime, dilution of mature fine tailings (MFT) in the lime supernatant and addition of...

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...

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)...

Freezing Characteristics of Mine Waste Tailings and their Relation to Unsaturated Soil Properties
DownloadSpring 2018
The study investigated the feasibility of using the soil freezing characteristic curve (SFCC) to estimate the soil water characteristic curve (SWCC) in mine waste tailings as an alternative to traditional SWCC testing. Traditional SWCC tests are challenging and time-consuming to conduct, taking...
