Developing a Reclamation Costing Framework for the Athabasca Oil Sands
Resource
The Athabasca oil sands are a significant component of the economy in Alberta. However, they also represent a large environmental risk. At the end of mining operations, companies are expected to begin...
Development and Application of Soil Quality Criteria for Alberta's Resource Extraction Industries
Resource
Soil quality criteria for Alberta's resource extraction industries were prepared by the Soil Quality Criteria Subcommittee of the Alberta Soils Advisory Committee. The document produced was intended...
Development of a Climate-Sensitive Structural Stand Density Management Model for Red Pine
Resource
The primary goal of this study was to develop a climate-sensitive modular-based structural stand density management model for red pine plantations situated within central North America. For a given...
Development of a Recovery Index to Quantify Ecological Recovery of Reclaimed Wellsites
Resource
Long-term monitoring of some sites would ultimately be needed to show that recovering wellsites are on a trajectory that consistently leads to full recovery.
Development of a Toxin-Mediated Predator-Prey Model Applicable to Aquatic Environments in the Athabasca Oil Sands Region
Resource
Previous work has considered the effect of a toxin on the population dynamics of a single trophic level, such as fish, we focus on the impacts of toxins on the population dynamics of aquatic food webs
Development of an Extraction Method for Estimating Phytoaccessible Fractions of Bromacil and Tebuthiuron
Resource
Bromacil and tebuthiuron are herbicides used from the 1960s to 1990s on industrial sites to control vegetation. Approximately 61,750 sites are considered contaminated when comparing total herbicide...
Development of Soil Quality Criteria for Contaminated Site Remediation
Resource
There can be little argument that contaminants are now a ubiquitous presence in our environment. Though large-scale efforts to deal with contaminant issues have traditionally focused on water and air...
Development of Three Slender Wheatgrass Reclamation Varieties
Resource
Three mid- to high-elevation lines of slender wheatgrass were selected and released as varieties for use in reclamation
Development of Two Alpine Bluegrass Reclamation Varieties
Resource
Two lines of alpine bluegrass were selected and released as varieties for use in reclamation
Développement juvénile de 25 familles de pin blanc (Pinus strobus L.) issues de pollinisation libre en plantations mélangées avec l'aulne rugueux (Alnus incana)
Resource
There is renewed interest in the management of eastern white pine ( Pinus strobus L.) for high-quality wood production. Several tree improvement programs have been implemented for the last few decades...
Dewatering Fine Tails by Evaporation: A Mathematical Modelling Approach
Resource
A one dimensional approach was used to model the evaporation process from fine tails. Understanding the complex interactions among the solids, water and external atmospheric demand is required
Differences in the Composition of Soils Under Open and Canopy Conditions at Two Sites Close-in to the Great Canadian Oil Sands Operation, Fort McMurray, Alberta
Resource
Soils sampled at sites 2.3 and 5.3 km south of the Great Canadian Oil Sands (GCOS) plant, Fort McMurray, respectively were found to differ statistically with reference to several macronutrients
Dimensionnement de la chaîne nationale d’approvisionnement en semences du Canada : Évaluation préliminaire sur les arbres et arbustes
Resource
In 2021-2022, the National Tree Seed Centre led a series of surveys to establish an accurate idea of genetically appropriate seed supply for forest landscape restoration (FLR) needs across Canada by...
Direct Planting of Poplar Stem Cuttings
Resource
Stem cuttings of balsam poplar and three poplar hybrids were directly planted onto reclamation material ontailings dyke slope. The overall rooting success was poor - direct planting is not recommended
Diseases of Black Spruce in Ontario
Resource
Over 70 diseases have been found and recorded on black spruce ( Picea mariana [Mill.] B.S.P.) in Ontario (Davis and Myren 1990). They range from vigorous pathogens capable of causing death or serious...
Disposal of Drilling Wastes in the Mountains
Resource
The foothills and mountain regions are extremely varied in soils, vegetation, climate and geology. Oil and gas drilling wastes must be contained ana then dispose □ of, despite of this extreme...
Dissipation of Bromacil in Humic Luvic Gleysols in Northwestern Alberta
Resource
Dissipation of bromacil in Humic Luvic Gleysols amended with cow manure was evaluated at two sites in northwestern Alberta from 1984 to 1987
