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...

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...

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)...

Impact of seedling characteristics, outplanting time, and container size on early establishment of aspen (Populus tremuloides) on reclamation sites
DownloadFall 2011
Aspen seedlings often suffer from transplant shock after outplanting. The influence of seedling characteristics and time of outplanting (spring, summer and fall) on field performance was examined on mining reclamation sites. Seedling characteristics were modified by inducing premature bud set...

Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlands
DownloadSpring 2016
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....

IMPACTS OF DISTANCE TO PIPELINE DISTURBANCE ON MIXED GRASS PRAIRIE AND HALIMOLOBOS VIRGATA (NUTT.) O.E. SCHULZ (SLENDER MOUSE EAR CRESS)
DownloadSpring 2014
Halimolobos virgata (slender mouse ear cress) is an at risk plant species in the Dry Mixed Grass Subregion of Southern Alberta. Little is known about effects of disturbances such as pipelines on Halimolobos virgata and its habitat. Environment Canada recommends a non species specific set back of...

Spring 2020
Soil stockpiles are used around the world to reclaim sites affected by industrial activities. Oil sands surface mining and in situ extraction activities in Alberta, Canada, have directly impacted more than 900 km2 of land, with more development expected in the future. Soil stockpiles will be...

Improving forb establishment and restoring soil function in disturbed landscapes: Hitchhiking native forbs with white spruce
DownloadSpring 2018
Changing requirements for land reclamation in Alberta has led to the need for revegetation of disturbed lands with native woody and herbaceous species. Our study involves âHitchhiker Plantingâ which is similar to companion cropping in agriculture, with the goal of improving native forb...

Influence of Amendments and Soil Depth on Available Nutrients and Microbial Dynamics in Contrasting Topsoil Materials Used for Oil Sands Reclamation
DownloadFall 2015
As of December 2013, the cumulative area disturbed by oil sands mining in NE Alberta was 896 km2 out of an estimated final footprint of 4,800 km2 – all of which will require reclamation. Expensive handling costs and scarce soil resources necessitate judicious management and application of...
