Spring 2020
Grasslands cover a quarter of the planet’s terrestrial surface and constitute 70% of the world’s agricultural land area. Grasslands provide clean water, facilitate effective nutrient cycling, and provide necessary habitat and forage for livestock and wildlife. In addition, grasslands have the...

Spring 2017
Achieving forest recovery on previously forested well sites in northern Alberta is an on-going challenge for the oil and gas industry. Thirty-three experimental oil sands exploration (OSE) sites were constructed and reclaimed between 2004 and 2006 in northeastern Alberta. Our goal was to...

Fall 2010
Bioclimate envelope models are widely used to project potential species habitat under changing climate. Conceptually, these models are also well suited to match natural resource management practices to new climatic realities, for example by guiding species choice in reforestation programs....

Spring 2015
Arsenic (As) concentration above the Health Canada and WHO drinking water guidelines of 10 µg L-1 in the Cold Lake area, Alberta is an issue of concern for environmental and human health. The source of groundwater As is ambiguous. This study was initiated to characterize the surficial deposits...

Disturbance Effects of Oil Sands Exploration Practices on Coarse-textured Soils and Populus tremuloides Michx. Regeneration
DownloadSpring 2018
Oils sands exploration (OSE) sites associated with in situ oil sands development are required to evaluate and delineate oil resources. Once these sites are cleared and disturbed for exploration, they can result in habitat disturbance and fragmentation, invasion of weed species, changes to surface...

Fall 2023
Western Canadian forests have been subject to periods of drought stress over the last three decades, resulting in growth reductions, dieback, and increased wildfires in the context of climate change. To contribute to adaptive forest management, this study compares drought vulnerabilities of eight...

EFFECTS OF CLIMATE CHANGE, VEGETATION AND ROADS ON CARIBOU DISTRIBUTION IN WESTERN NORTH-AMERICA
DownloadFall 2017
Caribou (Rangifer tarandus) are a vital component of the cultural history and contemporary existence of First Nations and northern communities. However, caribou habitat is increasingly threatened by cumulative effects of climate change and land-use pressures from human settlement, forestry, and...

Enhanced prediction of extreme fire weather conditions in spring using the Hot-Dry-Windy Index in Alberta, Canada
DownloadSpring 2023
Fire weather indices used to forecast fire behaviour provide valuable information for wildland fire prevention, preparedness, and suppression. The primary index used in Canada, the Fire Weather Index System, provides qualitative fuel moisture and fire behaviour indices. However, the indices used...

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)...

Factors affecting the detectability and eastern distribution of grizzly bears in Alberta, Canada
DownloadFall 2013
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...
