Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
DownloadFall 2022
Land-use change via human development is a major driver of biodiversity and habitat area loss and ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, aimed to compensate for authorized negative impacts. Studies evaluating offset project...

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...

Oil Sands Reclamation With Woody Debris Using LFH Mineral Soil Mix And Peat Mineral Soil Mix Cover Soils: Impacts On Select Soil And Vegetation Properties
DownloadFall 2014
Prior to mining oil sands, soil is salvaged for reclamation and forest stands are harvested for their merchantable timber. Harvest operations leave large amounts of residual woody debris, which has been historically burned or mulched. Woody debris has significant ecological effects and can be...

Persistence of subsoiling effects on the soil physical and hydraulic properties in a reconstructed soil
DownloadSpring 2016
Surface mining is one of the most significant forms of anthropogenic disturbance to natural and managed ecosystems. In Alberta, mining disturbs large areas in the Mixedwood Boreal natural region and recovery is often slow because of poor soil quality, specifically the high degree of compaction....

Physics of wastewater flow and pathogen transport processes from a soil-based at-grade effluent treatment system and associated groundwater contamination risks in Alberta, Canada
DownloadSpring 2015
Understanding of wastewater flow and transport processes and treatment effectiveness through the soil-absorption field of soil-based wastewater treatment systems remains a challenge. In addition, Alberta regulators and the on-site wastewater industry wanted to quantify the effectiveness of the...

Oil sands mining is a significant disturbance in the Canadian boreal forest. One objective for reclamation after mining is to create a self-sustaining ecosystem, which includes establishing a native plant community. For this thesis, study one evaluates the different plant assembly mechanisms,...

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...

Predicting Patterns of Regeneration on Seismic Lines to Inform Restoration Planning in Boreal Forest Habitats
DownloadFall 2014
Mapping of oil reserves involves the use of seismic lines (linear disturbances) to determine size of reserves. These linear disturbances fragment forests and in many cases fail to regenerate trees even decades following their use. With the continued rise in anthropogenic disturbances,...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Reclamation of thousands of limestone quarries around the world is challenged by an extremely limiting environment, including steep slopes, high calcium carbonate substrates with low nutrients and low water holding capacity. These issues were addressed at the Exshaw quarry in the Rocky Mountains...
