Assessing Spatial and Temporal Variation in Source Water Quality and Drinking Water Treatability Across a Gradient of Forest Harvest on Vancouver Island, BC
DownloadFall 2021
On Canada’s Pacific Coast, forestry is integral to society. Although economically important, harvesting practices may alter source waters that originate in forested watersheds through changes in suspended solids (SS) and dissolved organic matter (DOM). Each of these metrics has the potential to...

Assisted migration to address climate change: recommendations for reforestation in western Canada
DownloadFall 2011
A changing climate is the largest threat to forest productivity in western Canada and to the ability of forested landscapes to provide ecological and economic services, both now and in the future. As climate changes, locally adapted tree populations become mismatched with local conditions,...

Understory protection is a harvesting approach that seeks to protect understory conifers during hardwood harvesting in mixedwood forests. While understory protection harvesting has been implemented for over a decade in Alberta, there has been no study of its ecological value to birds. We surveyed...

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....

Diversity of wetland non-biting midges (Diptera: Chironomidae) and their responses to environmental factors in Alberta
DownloadSpring 2016
Wetlands provide a wide range of services, including improving water quality, providing habitats for wildlife, and storing floodwaters. In Alberta, wetlands cover about 21% of the landscape of the province. In Alberta, as elsewhere, wetlands have suffered from human activities and many have...

Influence of variable retention and deadwood characteristics on saproxylic beetles in boreal white spruce stands
DownloadSpring 2016
Retention forestry aims to maintain a significant level of continuity in forest structure, composition and complexity so as to support conservation and recovery of biodiversity and ecological function on managed landscapes; however, the amount and distribution of retention that best meets...

Spatial variations of total and dissolved trace elements and their distributions amongst major colloidal forms along and across the Lower Athabasca River
DownloadFall 2020
The Athabasca River (AR) is the longest river in Alberta with a wide variety of natural and potential anthropogenic inputs. The purpose of this study was to quantify the spatial variation of trace element (TE) concentrations and forms in this aquatic system. Water samples were gathered along a...

The Effect of Source Water Quality on Water Treatment Costs: Evaluation of Source Water Protection Practices
DownloadSpring 2020
A few high-profile forest fires and floods in recent history has exposed the vulnerability of Canadians’ drinking water supply systems to extreme events and their long-lasting consequences. Elevated levels of contaminants in surface waters can force downstream communities to engage in costly...

The potential influence of mountain pine beetle (Dendroctonus ponderosae) control harvesting on grizzly bear (Ursus arctos) food supply and habitat conditions in Alberta
DownloadFall 2012
In response to the mountain pine beetle (Dendroctonus ponderosae) threat in Alberta, forest companies plan to surge harvest 75% of susceptible (mature) lodgepole pine (Pinus contorta) stands over 20 years. To assess potential changes to grizzly bear (Ursus arctos) habitat, I projected food...

Fall 2011
This thesis presents results from an industrial aspen tree improvement program for Alberta, evaluating a series of provenance, clonal and hybrid field trials. The goals were to (1) investigate geographic patterns of genetic variation in order to delineate breeding regions, (2) to assess the...
